[0034] Those skilled in the art will understand that Figure 1 The structure shown is only for illustration and does not limit the structure of the above terminal device. Figure 1 More or fewer components than shown, or with Figure 1 Different configurations shown.

[0035] In a possible implementation, the present application provides a method for displaying a three-dimensional model of a game character. Figure 2is a flow chart of a method for displaying a three-dimensional model of a game character according to an embodiment of the present application, such as Figure 2 As shown, the method includes the following steps:

[0036] Step S202: determining a target three-dimensional model and a plurality of preset two-dimensional original texture layers.

[0037] In the technical solution provided in the above step S202 of the present application, the target three-dimensional model may be the three-dimensional character skin of a three-dimensional virtual character in a three-dimensional virtual scene, and multiple two-dimensional original texture layers may be generated by overlay rendering to form a three-dimensional virtual scene background for displaying the target three-dimensional model, and the multiple two-dimensional original texture layers are all in the coordinate system where the viewing frustum of the virtual camera is located. The three-dimensional virtual scene may be a scene corresponding to a real scene, or a game scene in the gaming field, and the viewing frustum may be a viewing frustum model, for example, a scene for displaying the skin of a virtual character in a gaming application, the three-dimensional virtual scene background may be a three-dimensional background in the three-dimensional virtual scene, the two-dimensional original texture layer may be a layer or texture layer component for generating a three-dimensional virtual scene, or may be a texture layer that needs to be resized to adapt to the image of the virtual camera, the virtual camera may be a perspective camera, and the viewing frustum of the virtual camera may be a pre-established viewing frustum model of a perspective camera, the viewing frustum may be used to represent the field of view of the virtual camera, and the coordinate system where the viewing frustum is located may be a two-dimensional coordinate system or a three-dimensional coordinate system, which is not specifically limited here.

[0038] Optionally, the multiple two-dimensional original texture layers are cropped separately so that the original sizes of the multiple two-dimensional original texture layers are unified to the same size, that is, the height and width of the multiple two-dimensional original texture layers can be the same. Optionally, this embodiment can determine the same size of the multiple two-dimensional original texture layers based on the model of the virtual camera in the three-dimensional virtual scene background. For example, when adjusting the two-dimensional original texture layer, the two-dimensional original texture layer is preferentially matched to the height of the virtual camera. The widest model of the virtual camera used to display the three-dimensional virtual scene background can be determined, and the width greater than the widest model is determined as the width in the above original size, so that the content of the generated three-dimensional virtual scene background can be displayed in the picture of the virtual camera of the widest model without leakage in the width direction, that is, to avoid the situation where the content of the three-dimensional virtual scene background in the width direction does not fill the picture of the virtual camera in the width direction, wherein the unfilled part can be represented as a part filled with black. It should be noted that when adjusting the two-dimensional original texture layer, it is prioritized to make the two-dimensional original texture layer match the height of the virtual camera. If the content of the three-dimensional virtual scene background in the width direction exceeds the picture of the virtual camera in the width direction, the part of the three-dimensional virtual scene background in the width direction that exceeds the picture of the virtual camera in the width direction can be cut off.

[0039] Step S204 : obtaining a size adjustment parameter of the two-dimensional original texture layer in the viewing frustum based on the relative position between the two-dimensional original texture layer and the virtual camera.

[0040] In the technical solution provided in the above step S204 of the present application, in the coordinate system where the viewing frustum of the virtual camera is located, the position of the virtual camera is determined as the origin position of the coordinate axis, so that the centers of multiple two-dimensional original texture layers and the position of the virtual camera are located on the same coordinate axis, and the relative position between each two-dimensional original texture layer and the virtual camera is determined. Based on the relative position, a size adjustment parameter of each two-dimensional original texture layer within the viewing frustum is determined, wherein the relative position may include the original coordinate position of each two-dimensional original texture layer in the coordinate system when the virtual camera is at the origin position of the coordinate system where the viewing frustum is located, and the size adjustment parameter may be a size scaling coefficient. For example, when adjusting the two-dimensional original texture layer, when the two-dimensional original texture layer is preferentially adjusted to match the height of the virtual camera, the size scaling coefficient may be a height scaling coefficient, which is used to adjust the height of the two-dimensional original texture layer.

[0041] Optionally, in this embodiment, the above-mentioned resizing parameters can be determined based on the setting parameters of the virtual camera's viewing frustum, for example, based on the near clipping plane distance, far clipping plane distance, and image aspect ratio of the viewing frustum, which are related to the corresponding two-dimensional original texture layer. That is, different two-dimensional original texture layers may have different corresponding resizing parameters.

[0042] Optionally, the size adjustment parameter can be the difference or ratio between the size of the target clipping plane of the two-dimensional original texture layer and the original size. When the size adjustment parameter is a ratio, the two-dimensional original texture layer is adjusted by multiplying or dividing the original size by the size adjustment parameter. When the size adjustment parameter is a difference, the two-dimensional original texture layer is adjusted by adding or subtracting the original size from the size adjustment parameter. The size of the target clipping plane can be the size that the two-dimensional original texture layer should have at the original coordinate position. For example, when adjusting the two-dimensional original texture layer, in order to prioritize matching the two-dimensional original texture layer with the height of the virtual camera, the size of the target clipping plane can be the height that the two-dimensional original texture layer should have at the original coordinate position.

[0043] It should be noted that before obtaining the size adjustment parameters of the two-dimensional original texture layer within the viewing frustum based on the relative position between the two-dimensional original texture layer and the virtual camera, a viewing frustum model can be established based on the construction parameters of the virtual camera, wherein the viewing frustum model is the viewing frustum in this embodiment, and the construction parameters of the virtual camera may include FOV parameters, near clipping plane distance parameters, far clipping plane distance parameters, and screen aspect ratio parameters, etc., which are not specifically limited here.

[0044] Step S206 : Based on the size adjustment parameter, the original size of the two-dimensional original texture layer is adjusted to the target size to obtain the target texture layer.

[0045] In the technical solution provided in the above step S206 of the present application, the original sizes of multiple two-dimensional original texture layers can be adjusted to the target size according to the calculated size adjustment parameters to obtain the target texture layer, and a three-dimensional virtual scene background is generated based on the multiple target texture layers, wherein the target size can be the final size of the two-dimensional original texture layer, and the size of the target texture layer can be the size of the corresponding clipping plane in the clipping space.

[0046] Optionally, as the distance between the target texture layer and the virtual camera increases from near to far, the target size of the target texture layer also increases from small to large.

[0047] Optionally, adjusting the original sizes of the plurality of two-dimensional original texture layers to the target size according to the calculated size adjustment parameters may include: multiplying, dividing, adding or subtracting the original sizes, which is not specifically limited here.

[0048] For example, when adjusting the original sizes of multiple two-dimensional original texture layers to the target size, the two-dimensional original texture layers are preferably matched with the height of the virtual camera. The height of the original size is 10 cm, and the size adjustment parameter is 5. When the size adjustment parameter is a ratio, adjusting the original size can be multiplying or dividing the original size by the size adjustment parameter, that is, if 10 is multiplied by 5, the target size is 50 cm, and if 10 is divided by 5, the target size is 2 cm. When the size adjustment parameter is a difference, adjusting the original size can be adding or subtracting the original size from the size adjustment parameter, that is, if 10 is added to 5, the target size is 15 cm, and if 10 is subtracted from 5, the target size is 5 cm.

[0049] Optionally, if the size of the two-dimensional original texture layer just matches the picture of the virtual camera, the size adjustment parameter of the above-mentioned two-dimensional original texture layer can make the target texture layer the same as the two-dimensional original texture layer. For example, if the size adjustment parameter is the ratio of the size of the target clipping plane of the two-dimensional original texture layer to the original size, the value of the size adjustment parameter is 1; if the size adjustment parameter is the difference between the size of the target clipping plane of the two-dimensional original texture layer and the original size, the value of the size adjustment parameter is 0.

[0050] Optionally, when adjusting the 2D original texture layer so as to prioritize matching the height of the virtual camera, the original height of the 2D original texture layer may be adjusted to the target height based on the height scaling parameter to obtain the target texture layer.

[0051] It should be noted that each two-dimensional original texture layer of this embodiment can be processed in the above manner to obtain a target texture layer, thereby obtaining multiple target texture layers for generating a three-dimensional virtual scene background.

[0052] Step S208 : generating a three-dimensional virtual scene background based on the target texture layer, and displaying the target three-dimensional model in the three-dimensional virtual scene background.

[0053] In the technical solution provided in the above-mentioned step S208 of the present application, after each two-dimensional original texture layer is adjusted according to the corresponding size adjustment parameter to obtain multiple target texture layers, special effects can be added between each adjacent target texture layer in the multiple target texture layers to finally generate a three-dimensional virtual scene background, and the target three-dimensional model is displayed in the three-dimensional virtual scene background to achieve the purpose of enhancing the spatial sense of the three-dimensional virtual scene background and enriching the performance effect of the three-dimensional virtual scene background. Among them, the position of adding special effects between each adjacent target texture layer can be determined according to the scene construction requirements, and no specific limitation is made here.

[0054] Through the above steps S202 to S208 of the present application, the target three-dimensional model and multiple preset original texture layers are determined; based on the construction parameters of the virtual camera, a viewing cone model is established, and then based on the relative position between the two-dimensional original texture layer and the virtual camera, the size adjustment parameters of the two-dimensional original texture layer within the viewing cone are obtained; based on the size adjustment parameters, the original size of the two-dimensional original texture layer is adjusted to the target size to obtain the target texture layer; and a virtual scene is generated based on the target texture layer corresponding to each two-dimensional original texture layer. In the embodiment of the present application, the original size of each two-dimensional original texture layer can be automatically adjusted by the preset size adjustment parameters of the two-dimensional original texture layer within the viewing cone to obtain the target texture layer, and finally a three-dimensional virtual scene background is generated based on the target texture layer corresponding to the two-dimensional original texture layer, and the target three-dimensional model is displayed in the three-dimensional virtual scene background, thereby achieving the purpose of generating a three-dimensional virtual scene background for a virtual character by superimposing two-dimensional texture layers, thereby solving the technical problem of the virtual scene background lacking three-dimensional sense and achieving the technical effect of enhancing the three-dimensional sense of the virtual scene background.

[0055] The above method of this embodiment is further introduced below.

[0056] As an optional implementation, step S204, based on the relative position between the two-dimensional original texture layer and the virtual camera, obtaining a resizing parameter of the two-dimensional original texture layer within the viewing frustum, includes: obtaining the resizing parameter based on the original coordinate position of the center of the two-dimensional original texture layer on the coordinate axis.

[0057] In this embodiment, the centers of multiple two-dimensional original texture layers and the position of the virtual camera are located on the same coordinate axis, and the position of the virtual camera can be the origin of the coordinate axis. The multiple two-dimensional original texture layers are arranged in sequence on the coordinate axis to obtain the original coordinate positions of the multiple two-dimensional original texture layers on the coordinate axis. Then, according to the original coordinate positions, the size adjustment parameters corresponding to the two-dimensional original texture layers at the original coordinate positions are obtained, and the size of the two-dimensional original texture layer is adjusted based on the size adjustment parameters, wherein the two-dimensional original texture layer is a plane image, the center of the two-dimensional original texture layer can be the geometric center of the two-dimensional original texture layer, the origin of the coordinate axis can be the zero point of the coordinate axis, the original coordinate position can be the coordinate position of the two-dimensional original texture layer on the coordinate axis, and the size adjustment parameter can be a size scaling factor. For example, when adjusting the two-dimensional original texture layer, when the two-dimensional original texture layer is preferentially made to match the height of the virtual camera, the size scaling factor can be a height scaling factor, which is used to adjust the height of the two-dimensional original texture layer.

[0058] For example, the centers of multiple two-dimensional original texture layers and the virtual camera are located on the Z axis of the coordinate system, the position of the virtual camera is the zero position of the Z axis, and the multiple two-dimensional original texture layers are arranged in sequence on the Z axis to obtain the original coordinate positions of the multiple two-dimensional original texture layers on the coordinate axis, that is, the original coordinate position of texture layer 1 is Z1, the original coordinate position of texture layer 2 is Z2, and the original coordinate position of texture layer 3 is Z3. Then, the size adjustment parameters of texture layer 1 at Z1, the size adjustment parameters of texture layer 2 at Z2, and the size adjustment parameters of texture layer 3 at Z3 are obtained respectively.

[0059] As an optional embodiment, the method may further include obtaining a size adjustment parameter of the two-dimensional original texture layer within the viewing frustum based on the original coordinate position of the center of the two-dimensional original texture layer on the coordinate axis, including: determining the size of the target clipping plane corresponding to the original coordinate position in the clipping space; and determining the size adjustment parameter based on the size of the target clipping plane and the original size.

[0060] In this embodiment, the size of the target clipping plane corresponding to the two-dimensional original texture layer at the original coordinate position can be first determined in the clipping space of the virtual camera, and then the difference or ratio between the size of the target clipping plane of the two-dimensional original texture layer at the original coordinate position and the original size can be determined as the size adjustment parameter, wherein the original size can be the original size of the two-dimensional original texture layer, and the size of the target clipping plane can be the size that the two-dimensional original texture layer should have at the original coordinate position. For example, when adjusting the two-dimensional original texture layer to prioritize matching the height of the virtual camera, the original size can be the original height of the two-dimensional original texture layer, and the size of the target clipping plane can be the height that the two-dimensional original texture layer should have at the original coordinate position.

[0061] Optionally, the size adjustment parameter can be calculated using the following formula:

[0062]

[0063] In the above formula, S Z Can be used to represent the size adjustment parameter, that is, the size scaling factor, H Z It can be used to represent the size of the target clipping plane of the two-dimensional original texture layer, H o Can be used to represent the original size of a 2D original texture layer.

[0064] For example, when adjusting the two-dimensional original texture layer, the priority is to make the two-dimensional original texture layer match the height of the virtual camera. Z It can be a height scaling factor, which is used to adjust the height of the original two-dimensional texture layer and the size of the target clipping plane H. Z Can be the height of the target clipping plane, the original size H o It can be the height of the 2D original texture layer.

[0065] As an optional embodiment, the method may further include determining the size of the target clipping plane corresponding to the original coordinate position in the clipping space, including: determining a first predetermined clipping plane and a second predetermined clipping plane in the clipping space; determining the size of the target clipping plane based on the size of the first predetermined clipping plane, the size of the second predetermined clipping plane, the first coordinate position of the center of the first predetermined clipping plane on the coordinate axis, the second coordinate position of the center of the second predetermined clipping plane on the coordinate axis, and the original coordinate position.

[0066] In this embodiment, a first predetermined clipping plane and a second predetermined clipping plane may be first determined in the clipping space. Then, according to the principle of similar triangles and the principle of linear mapping, the size of the target clipping plane may be calculated based on the size of the first predetermined clipping plane, the size of the second predetermined clipping plane, the first coordinate position of the center of the first predetermined clipping plane on the coordinate axis, the second coordinate position of the center of the second predetermined clipping plane on the coordinate axis, and the original coordinate position. The first predetermined clipping plane may be a near clipping plane, the second predetermined clipping plane may be a far clipping plane, the size of the first predetermined clipping plane may be the size of the near clipping plane, and the size of the second predetermined clipping plane may be the size of the far clipping plane. For example, when adjusting a two-dimensional original texture layer so as to preferentially match the height of a virtual camera, the size of the first predetermined clipping plane may be the height of the near clipping plane, the size of the second predetermined clipping plane may be the height of the far clipping plane, the first coordinate position may be the distance between the first predetermined clipping plane and the virtual camera, and the second coordinate position may be the distance between the second predetermined clipping plane and the virtual camera. The distance between the first predetermined clipping plane and the virtual camera is smaller than the distance between the second predetermined clipping plane and the virtual camera.

[0067] Optionally, the size of the target clipping plane can be calculated using the following formula:

[0068]

[0069] In the above formula, Z can be used to represent the original coordinate position of the two-dimensional original texture layer on the Z axis, D f It can be used to represent the distance between the near clipping plane and the virtual camera, D b It can be used to represent the distance between the far clipping plane and the virtual camera, H Z Can be used to indicate the size of the target clipping plane, H f Can be used to represent the size of the first predetermined clipping plane, H b It can be used to represent the size of the second predetermined clipping plane. For example, when adjusting the two-dimensional original texture layer, the two-dimensional original texture layer is preferably matched with the height of the virtual camera. Z Can be the height of the target clipping plane, H f Can be the height of the near clipping plane, H b Can be the height of the far clipping plane.

[0070] As an optional implementation, the method may further include determining a size of the first predetermined clipping plane based on the field of view angle of the virtual camera and the first coordinate position.

[0071] In this embodiment, it can be seen from the tangent trigonometric function that the ratio of half the size of the near clipping plane to the distance between the near clipping plane and the virtual camera is the tangent value of half the field of view angle. Therefore, the size of the first predetermined clipping plane can be calculated by the field of view angle of the virtual camera and the first coordinate position, where the field of view angle can be the Fov of the perspective camera, that is, the range that the perspective camera lens can cover.

[0072] Optionally, the size of the first predetermined clipping plane can be calculated using the following formula:

[0073]

[0074] In the above formula, H f It can be used to represent the size of the first predetermined clipping plane. For example, when adjusting the two-dimensional original texture layer, the two-dimensional original texture layer is prioritized to match the height of the virtual camera. f It can be the height of the first predetermined clipping plane, D f It can be used to represent the first coordinate position, that is, the distance between the first predetermined clipping plane and the virtual camera. Fov can be used to represent the field of view angle of the virtual camera.

[0075] As an optional implementation, the method may further include determining a size of a second predetermined clipping plane based on the field of view angle of the virtual camera and the second coordinate position.

[0076] In this embodiment, it can be seen from the tangent trigonometric function that the ratio of half the size of the far clipping plane to the distance between the far clipping plane and the virtual camera is also the tangent value of half the field of view angle. Therefore, the size of the second predetermined clipping plane can be calculated using the field of view angle of the virtual camera and the second coordinate position.

[0077] Optionally, the size of the second predetermined clipping plane can be calculated using the following formula:

[0078]

[0079] In the above formula, H b It can be used to represent the size of the second predetermined clipping plane. For example, when adjusting the two-dimensional original texture layer, the two-dimensional original texture layer is preferably matched with the height of the virtual camera. b It can be the height of the second predetermined clipping plane, D b It can be used to represent the second coordinate position, that is, the distance between the second predetermined clipping plane and the virtual camera. Fov can be used to represent the field of view angle of the virtual camera.

[0080] As an optional implementation, step S206, based on the size adjustment parameter, adjusts the original size of the two-dimensional original texture layer to the target size, including: adjusting the original size according to the size adjustment parameter to obtain the target size that is the same as the size of the target clipping plane.

[0081] In this embodiment, the original sizes of multiple two-dimensional original texture layers can be adjusted respectively according to the obtained size adjustment parameters, and adjusted to a target size that is the same as the size of the target clipping plane, wherein the target size is positively correlated with the distance between the original coordinate position and the virtual camera, that is, as the distance between the two-dimensional original texture layer and the virtual camera goes from near to far, the target size corresponding to the two-dimensional original texture layer becomes larger and larger.

[0082] Optionally, when adjusting the original sizes of the multiple two-dimensional original texture layers, they may be scaled accordingly according to the obtained size adjustment parameters, for example, by multiplying, dividing, adding or subtracting the original sizes, which is not specifically limited here.

[0083] For example, when adjusting the original sizes of multiple two-dimensional original texture layers to the target size, the two-dimensional original texture layers are preferably matched with the height of the virtual camera. The height of the original size is 10 cm, and the size adjustment parameter is 5. When the size adjustment parameter is a ratio, adjusting the original size can be multiplying or dividing the original size by the size adjustment parameter, that is, if 10 is multiplied by 5, the target size is 50 cm, and if 10 is divided by 5, the target size is 2 cm. When the size adjustment parameter is a difference, adjusting the original size can be adding or subtracting the original size from the size adjustment parameter, that is, if 10 is added to 5, the target size is 15 cm, and if 10 is subtracted from 5, the target size is 5 cm.

[0084] Optionally, if the original size of the two-dimensional original texture layer is exactly the same as the target size, then when the size adjustment parameter is the ratio of the size of the target clipping plane of the two-dimensional original texture layer to the original size, the value of the size adjustment parameter is 1; when the size adjustment parameter is the difference between the size of the target clipping plane of the two-dimensional original texture layer and the original size, the value of the size adjustment parameter is 0.

[0085] As an optional implementation, step S208, generating a three-dimensional virtual scene background based on the target texture layer, includes: in response to the original coordinate position remaining unchanged, constructing the target texture layer corresponding to each two-dimensional original texture layer into a three-dimensional virtual scene background.

[0086] In this embodiment, after the original sizes of multiple two-dimensional original texture layers are adjusted to target sizes according to the obtained size adjustment parameters, a target texture layer corresponding to each two-dimensional original texture layer is obtained, and the original coordinate position is kept unchanged. The generated multiple target texture layers can be constructed as a three-dimensional virtual scene background at the original coordinate position of the two-dimensional original texture layer.

[0087] As an optional embodiment, the method may also include, multiple two-dimensional original texture layers corresponding to multiple target texture layers, wherein, based on the target texture layer corresponding to each two-dimensional original texture layer, a three-dimensional virtual scene background is generated, including: special effects data between each adjacent target texture layer in the multiple target texture layers, and the target texture layer corresponding to each two-dimensional original texture layer, are constructed into a three-dimensional virtual scene background.

[0088] In this embodiment, based on the special effect data between each adjacent target texture layer, special effect data is added at the required position between each adjacent target texture layer in multiple target texture layers, and then based on the target texture layer corresponding to each two-dimensional original texture layer, a three-dimensional virtual scene background is constructed to enhance the spatial sense of the three-dimensional virtual scene background and enrich the performance effect of the three-dimensional virtual scene background. Among them, the special effect data can be used to generate special effects in the three-dimensional virtual scene background, and the special effect can be a motion effect.

[0089] Optionally, the position of adding special effects between each adjacent target texture layer in the multiple target texture layers can be determined according to the scene construction requirements, and is not specifically limited here.

[0090] As an optional embodiment, the method may further include: the original size includes the original width of the two-dimensional original texture layer and the original height of the two-dimensional original texture layer, the size of the clipping plane in the clipping space includes the target width of the clipping plane in the clipping space and the target height of the clipping plane in the clipping space, and the ratio between the original width and the original height is greater than the ratio between the target width and the target height.

[0091] In this embodiment, the original size of the two-dimensional original texture layer may include the original width of the two-dimensional original texture layer and the original height of the two-dimensional original texture layer, the size of the clipping plane in the clipping space may include the target width of the clipping plane in the clipping space and the target height of the clipping plane in the clipping space, the ratio between the original width and the original height is greater than the ratio between the target width and the target height, so that the content of the generated three-dimensional virtual scene background can be displayed in the picture of the virtual camera of the widest model without leakage in the width direction, that is, avoiding the situation where the content of the three-dimensional virtual scene background in the width direction does not fill the picture of the virtual camera in the width direction, wherein the unfilled part can be expressed as a part filled with black, and the target width of the clipping plane and the target height of the clipping plane in the clipping space can be the width and height of the device screen used to display the three-dimensional virtual scene background.

[0092] It should be noted that, in the embodiment of the present application, adjusting the height of the two-dimensional original texture layer based on the size adjustment parameter is only an example to adapt to actual application scenarios and is not specifically limited here.

[0093] The technical solutions of the embodiments of the present application are further described below with reference to preferred implementation methods.

[0094] In a related technology, a virtual scene can be displayed by building a real three-dimensional (3D) scene, for example, a scene showing the skins of various characters in the Egg Party game. Figure 3 is a schematic diagram of a virtual scene generated according to a related technology of an embodiment of the present application, such as Figure 3 As shown, when building a scene with this method, it is necessary to design a display scene layout and produce component models required for the corresponding scene. The model reuse rate is low, resulting in high labor costs for scene construction. In addition, the large number of high-polygon components in the scene and the rendering-related consumption will also affect the game performance.

[0095] In another related technology, a virtual scene can be displayed through a single background texture layer, for example, the game scene displayed in the King of Glory game. Figure 4 is a schematic diagram of a virtual scene generated according to another related technology of an embodiment of the present application, such as Figure 4 As shown, a single texture layer will cause the display scene to lack a sense of three-dimensionality, making the display effect rather stiff. In addition, in order to make the texture layer adapt to the camera screen size, the position and size of the texture layer need to be manually adjusted, which not only leads to low matching accuracy between the screen size and the texture layer, but also there is a technical problem that the virtual scene background lacks a sense of three-dimensionality.

[0096] However, this embodiment of the present application provides a method for generating a virtual scene based on multi-layer textures. The method uses multi-layer textures in combination with special effects between texture layers to achieve a pseudo 3D effect. In order to make each layer of texture adapt to the camera screen size, a camera frustum model is constructed through the relevant parameters of the scene perspective camera. The accurate position information and corresponding size of each layer of texture are then calculated, and then the position of each layer of texture relative to the scene perspective camera is adjusted, thereby solving the technical problems of low matching accuracy between the screen size and the texture layer, and lack of three-dimensional sense of the virtual scene background.

[0097] The above method provided in this embodiment of the present application is further introduced below. The method may include the following four parts.

[0098] In the first part, the prepared multiple texture layers are unified into the same size, and the center position of each texture layer is at its geometric center, and each texture layer is arranged on the same axis as the in-game perspective camera.

[0099] Optionally, the uniform aspect ratio of the same size must meet the requirements of the widest model to avoid leakage of the generated virtual scene in different models.

[0100] Figure 5 is a schematic diagram of a plurality of texture layers being unified into the same size according to an embodiment of the present application, such as Figure 5 As shown, texture layer 1, texture layer 2 and texture layer 3 are of the same size, and texture layer 1, texture layer 2 and texture layer 3 are arranged on the same axis (for example, Z axis) as perspective camera 4. That is, the geometric center of each texture layer and the perspective camera are both on the Z axis, and each texture layer is arranged from near to far according to the position relationship along the camera ray direction.

[0101] Figure 6 is a schematic diagram of a texture layer of a default size within the camera's viewing angle according to an embodiment of the present application, such as Figure 6 As shown, within the perspective camera angle of view, the default sizes of texture layer 1, texture layer 2, and texture layer 3 do not match the camera image, and the relative sizes and positions of the layers are disordered.

[0102] In the second part, we obtain the setting parameters of the perspective camera: FOV, near clipping plane distance, far clipping plane distance, and screen aspect ratio, and use them to build the perspective camera's viewing cone model.

[0103] Figure 7 is a schematic diagram of a viewing cone model of a perspective camera according to an embodiment of the present application, such as Figure 7 As shown, point A is located at perspective camera 1, point B is located at near clipping plane 3, and point C is located at far clipping plane 4. Field of view angle 2 represents the FOV of perspective camera 1, and the black solid line on near clipping plane 3 represents the width of near clipping plane 3 (Width front, Wf ), the black dotted line indicates the height of the near clipping surface 3 (High front, H f ), point A to point B on the near clipping surface 3, that is, line segment AB, represents the distance from the near clipping surface (Distancefront, D f ), the black solid line on the far clipping plane 4 represents the width of the far clipping plane 4 (Width back, W b ), the black dotted line indicates the height of the far clipping plane 4 (High back, H b ), point A to point C on the far clipping plane 4, that is, line segment AC, represents the distance back to the far clipping plane (Distance back, D b ).

[0104] In order to facilitate understanding of the calculation principle and calculation process of the embodiment of the present application, the embodiment of the present application also provides a side view of the cone model. Figure 8 is a schematic diagram of a side view of a viewing cone model of a perspective camera according to an embodiment of the present application, such as Figure 8 As shown, point A is located at perspective camera 1, field of view angle 2 represents the FOV of perspective camera 1, the black solid line represents the near clipping plane 3, point B is located at the near clipping plane 3, and the length of the black solid line represents the height H of the near clipping plane 3. f , the black dotted line represents the far clipping plane 4, point C is located on the far clipping plane 4, and the length of the black dotted line represents the height H of the far clipping plane 4 b , line segment AB represents the distance D from the near clipping surface f , line segment AC represents the distance D from the far clipping plane b .

[0105] From the tangent trigonometric function, we know that the ratio of half the height of the near clipping plane to the distance to the near clipping plane is the tangent value of half the field of view angle, which can be expressed by the following formula:

[0106]

[0107] The height H of the near clipping surface can be obtained by the above formula f , that is,

[0108]

[0109] In the above formula, tan can be used to represent the tangent function, Fov can be used to represent the field of view, H f Can be used to represent the height of the near clipping plane, D f Can be used to represent the near clipping plane distance.

[0110] Similarly, the ratio of half the height of the far clipping plane to the distance to the far clipping plane is also the tangent of half the field of view angle, which can be expressed by the following formula:

[0111]

[0112] The height H of the far clipping plane can be obtained by the above formula b , that is,

[0113]

[0114] In the above formula, H b Can be used to represent the height of the far clipping plane, D b Can be used to represent the far clipping plane distance.

[0115] Since the aspect ratio of the perspective camera is a camera setting parameter, the width of the near clipping plane and the width of the far clipping plane can be solved according to the camera aspect ratio formula, that is,

[0116]

[0117] In the above formula, Ratio can be used to represent the aspect ratio of the perspective camera, W can be used to represent the width of the perspective camera image, for example, the width of the near clipping plane or the width of the far clipping plane, and H can be used to represent the height of the perspective camera image, for example, the height of the near clipping plane or the height of the far clipping plane.

[0118] It should be noted that the method for solving the width value of the near clipping plane and the width value of the far clipping plane is an extension of the embodiment of the present application, and the solved width value of the near clipping plane and the width value of the far clipping plane are not applied in the embodiment of the present application.

[0119] The third part sets the position of each texture layer on the Z axis according to the position relationship of each texture layer.

[0120] Figure 9 is a schematic diagram of the position of a texture layer in a viewing cone model according to an embodiment of the present application, such as Figure 9 As shown, the black solid line represents the near clipping plane, the black dotted line represents the far clipping plane, the position of the perspective camera 4 is at the zero point of the Z axis, the position of texture layer 1 (Layer 1) is Z1, the position of texture layer 1 (Layer 2) is Z2, and the position of texture layer 3 (Layer 3) is Z3.

[0121] In order to make each texture layer accurately adapt to the size of the perspective camera screen, it is necessary to adjust the size of each texture layer at the corresponding position. According to the principle of similar triangles and the principle of linear mapping, the formula for calculating the size of the texture layer is as follows:

[0122]

[0123] In the above formula, H Z It can be used to indicate the height that the texture layer should have at the corresponding position, Hf Can be used to represent the height of the near clipping plane, H b It can be used to indicate the height of the far clipping plane, Z can be used to indicate the corresponding position of the texture layer on the Z axis, D f Can be used to indicate the distance to the near clipping plane, D b Can be used to represent the distance of the far clipping plane.

[0124] After obtaining the height that the texture layer should have at the corresponding position, the corresponding scaling factor can be obtained by the ratio of the height that the texture layer should have at this position to its original height, which can be expressed by the following formula:

[0125]

[0126] In the above formula, H o Can be used to represent the original height of the texture layer, S Z Can be used to indicate the corresponding scaling factor.

[0127] Figure 10 is a schematic diagram of each texture layer after the size is modified according to the scaling factor at the corresponding position according to an embodiment of the present application, such as Figure 10 As shown, the texture layers 1, 2 and 3 are resized according to the scaling factors at the corresponding positions. Figure 11 This is a schematic diagram of the image within the camera's field of view after each texture layer is resized according to the scaling factor at the corresponding position according to an embodiment of the present application, such as Figure 11 As shown, each texture layer accurately matches the perspective camera image.

[0128] Optionally, each texture layer whose size is modified according to the scaling factor at the corresponding position remains at the corresponding original position and satisfies the rule of increasing size from near to far.

[0129] In the fourth part, add special effects at the desired locations between the texture layers.

[0130] Figure 12 is a schematic diagram of generating a virtual scene effect according to an embodiment of the present application, such as Figure 12 As shown, after adjusting the size of each texture layer according to the scaling factor at the corresponding position, special effects can be added between the texture layers according to the scene construction requirements to enhance the spatial sense of the scene and enrich the scene performance effect.

[0131] The beneficial effects brought about by the technical solution of the embodiment of the present application may include: avoiding the problems of excessively high costs and high performance consumption caused by constructing a three-dimensional display scene, and achieving effects that meet requirements; avoiding the problems of low efficiency and low precision caused by traditional manual adjustment of the parameters of each texture layer, and automatically calculating the accurate position information and corresponding size of each texture layer, so that each texture layer can accurately adapt to the camera screen size.

[0132] In an embodiment of the present application, a camera frustum model is constructed based on the relevant parameters of the scene perspective camera, and then the accurate position information and corresponding size of each layer of texture are calculated. Finally, the position of each layer of texture relative to the scene perspective camera is adjusted, and special effects are added between texture layers. This technical solution solves the technical problem of the lack of three-dimensional sense in the virtual scene background and achieves the technical effect of enhancing the three-dimensional sense of the virtual scene background.
