[0032] Before explaining the embodiments of the present application in detail, some terms involved in the embodiments of the present application are first explained.

[0037] The following is a detailed description of the embodiments in conjunction with the accompanying drawings. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Although the logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown in the accompanying drawings.
[0038] In this embodiment, a terminal is used as an example for illustration. This embodiment provides a model rendering method, such as Figure 1 As shown, the specific process of the model rendering method can be as follows:
[0039] 101. Obtain the spatial coordinates of the model to be rendered in the target coordinate space.
[0040] Among them, the model to be rendered refers to the geometric description of the virtual object, and the type of the virtual object can be set according to the actual situation. For example, the virtual object can be a virtual animal or a virtual cloud, which is not limited in the embodiment of the present application.
[0041] The target coordinate space refers to a three-dimensional geometric space where the model to be rendered is located. Its type can be set according to actual conditions. For example, the target coordinate space can be one of the world coordinate space or model coordinate space of the model to be rendered. The embodiment of the present application does not limit this.
[0042] When the target coordinate space is a world coordinate space, the spatial coordinates of the model to be rendered in the target coordinate space can be called the world coordinates of the model to be rendered. When the target coordinate space is a model coordinate space, the spatial coordinates of the model to be rendered in the target coordinate space can be called the model coordinates of the model to be rendered.
[0043] The terminal may obtain the spatial coordinates of the model to be rendered in the target coordinate space upon receiving a rendering instruction of the model to be rendered sent by other devices, or the terminal may also obtain the spatial coordinates of the model to be rendered in the target coordinate space in response to a trigger operation of the user.
[0044] The manner in which the terminal obtains the spatial coordinates of the model to be rendered in the target coordinate space can be set according to actual conditions, and the embodiments of the present application are not limited thereto.
[0045] 102. Normalize the spatial coordinates to obtain normalized spatial coordinates.
[0046] Among them, the method of normalizing the spatial coordinates can be set according to actual conditions, and the embodiment of the present application is not limited here.
[0047] For example, the process of normalizing the spatial coordinates to obtain the normalized spatial coordinates can be:
[0048] Determine a first difference between the maximum value and the minimum value corresponding to each component coordinate in the spatial coordinate;
[0049] Subtract the minimum value corresponding to each component coordinate from each component coordinate in the spatial coordinate to obtain a second difference value;
[0050] The second difference value corresponding to each component coordinate in the spatial coordinate is divided by the first difference value corresponding to each component coordinate to obtain a normalized spatial coordinate.
[0051] Among them, the component coordinates refer to the coordinates of the spatial coordinates on a certain coordinate axis. For example, if the spatial coordinates are (x11, y11, z11), the component coordinates can be the coordinates x11 on the x-axis, y11 on the y-axis, and z11 on the z-axis. The maximum value corresponding to each component coordinate refers to the maximum value of the spatial coordinate on a certain coordinate axis, and the minimum value corresponding to each component coordinate refers to the minimum value of the spatial coordinate on a certain coordinate axis. For example, the spatial coordinates include (x11, y11, z11), (x12, y12, z12) and (x13, y13, z13), among which, on the x-axis, x13 is the largest and x11 is the smallest. The maximum value corresponding to the component coordinates on the x-axis is x13, the minimum value is x11, and the first difference is (x13- x11), on the y-axis, y13 is the largest and y11 is the smallest, the maximum value corresponding to the component coordinate on the y-axis is y13, the minimum value is y11, and the first difference is (y13-y11). On the z-axis, z13 is the largest and z11 is the smallest, the maximum value corresponding to the component coordinate on the z-axis is z13, the minimum value is z11, and the first difference is (z13-z11). For x11, the second difference is (x11-x11), and for x12, the second difference is (x12-x11).
[0052] In an embodiment of the present application, a first difference between the maximum value and the minimum value corresponding to each component coordinate in the spatial coordinate is determined, the minimum value corresponding to each component coordinate in the spatial coordinate is subtracted from the minimum value to obtain a second difference, and the second difference corresponding to each component coordinate in the spatial coordinate is divided by the first difference corresponding to each component coordinate to obtain a normalized spatial coordinate, thereby achieving normalization processing of the spatial coordinates.
[0053] Alternatively, the process of normalizing the spatial coordinates to obtain the normalized spatial coordinates may also be:
[0054] Get the bounding box parameters of the model to be rendered;
[0055] According to the bounding box parameters, the space coordinates are normalized to obtain normalized space coordinates.
[0056] The bounding box of the model to be rendered refers to a geometric body that approximately replaces the model to be rendered. The bounding box parameters of the model to be rendered refer to parameters used to describe the bounding box of the model to be rendered. For example, the bounding box parameters can be at least one of the bounding box size and the spatial coordinates of the bounding box in the target coordinate space, which is not limited in the embodiments of the present application.
[0057] In an embodiment of the present application, the bounding box parameters of the model to be rendered are obtained, and the spatial coordinates are normalized according to the bounding box parameters to obtain normalized spatial coordinates, so that the spatial coordinates of the model to be rendered are normalized with the center of the bounding box as the origin, so that the model rendered by the thickness value determined according to the normalized coordinates of the model to be rendered has a better light transmission effect.
[0058] In some embodiments, when the center of the target coordinate space is the center of the model to be rendered and the bounding box parameters are the bounding box sizes of the bounding box on each coordinate axis, the space coordinates are normalized according to the bounding box parameters to obtain the normalized space coordinates as follows:
[0059] Divide the spatial coordinates by the bounding box size of the bounding box on each coordinate axis to obtain the normalized spatial coordinates.
[0060] For example, the spatial coordinates are (x11, y11, z11), and the size of the bounding box on the x-axis is s x , the bounding box size on the y axis is s y , the bounding box size on the z-axis is s z , then the normalized spatial coordinates are (x11 / s x ,y11 / s y , z11 / s z ).
[0061] In some embodiments, the space coordinates are normalized according to the bounding box parameters to obtain normalized space coordinates, including:
[0062] Get the center coordinates of the model to be rendered in the target coordinate space;
[0063] Determine the change coordinates between the space coordinates and the center coordinates;
[0064] According to the bounding box parameters and the change coordinates, the space coordinates are normalized to obtain normalized space coordinates.
[0065] The center coordinates of the model to be rendered in the target coordinate space refer to the coordinates corresponding to the center of all vertices of the model to be rendered in the target coordinate space. Since the center coordinates of the model to be rendered in the target coordinate space are not necessarily the origin of the coordinate system corresponding to the target coordinate space, the center coordinates are subtracted from the space coordinates to obtain the changed coordinates.
[0066] After obtaining the changed coordinates, if the bounding box parameters are the spatial coordinates of the bounding box in the target coordinate space, first determine the bounding box size based on the spatial coordinates of the bounding box in the target coordinate space, and then divide the changed coordinates by the bounding box size. If the bounding box parameters are the bounding box size, then directly divide the changed coordinates by the bounding box size.
[0067] For example, the spatial coordinates are (x11, y11, z11), the center coordinates are (x0, y0, z0), and the bounding box size on the x-axis is s x , the bounding box size on the y axis is s y , the bounding box size on the z-axis is s z , then the normalized spatial coordinate is ((x11-x0) / s x , (y11-y0) / s y , (z11-z0) / s z ).
[0068] It is understandable that the center coordinates of the model to be rendered in the target coordinate space can be directly read, or the bounding box parameters can include the spatial coordinates of the bounding box in the target coordinate space, and the center coordinates of the model to be rendered in the target coordinate space can be determined based on the spatial coordinates of the bounding box in the target coordinate space. Specifically, the maximum value and the minimum value of the spatial coordinates of the bounding box in the target coordinate space can be added, and the addition result can be divided by 2 to obtain the center coordinates of the model to be rendered in the target coordinate space.
[0069] For example, the center coordinates are (x0, y0, z0), and the spatial coordinates of the bounding box in the target coordinate space include (x21, y21, z21), (x22, y22, z22) and (x23, y23, z23). Among x21, x22 and x23, x21 is the minimum value and x23 is the maximum value, then x0 = (x23 + x21) / 2, among y21, y22 and y23, y21 is the minimum value and y23 is the maximum value, then y0 = (y23 + y21) / 2, among z21, z22 and z23, z21 is the minimum value and z23 is the maximum value, then x0 = (z23 + z21) / 2.
[0070] In an embodiment of the present application, the center coordinates of the model to be rendered in the target coordinate space are obtained, the change coordinates between the spatial coordinates and the center coordinates are determined, and the spatial coordinates are normalized according to the bounding box parameters and the change coordinates to obtain normalized spatial coordinates. This ensures that the normalization effect of the spatial coordinates can be achieved even if the center coordinates of the model to be rendered in the target coordinate space are not the origin of the coordinate system corresponding to the target coordinate space.
[0071] In some embodiments, when the target coordinate space is the world coordinate space and the spatial coordinates are normalized according to the bounding box parameters, since after the model to be rendered is rotated, in the world coordinate space, the edges of the bounding box are not parallel to the coordinate axes of the world coordinate system. Therefore, if the spatial coordinates are normalized according to the bounding box parameters in the world coordinate space, the thickness value determined according to the normalized spatial coordinates will be inaccurate.
[0072] For example, Figure 2 As shown, in the model coordinate space, the model to be rendered is rotated. After the rotation, the edges of the bounding box of the model to be rendered are still parallel to the coordinate axes of the model coordinate system. However, in the world coordinate space, the edges of the bounding box of the model to be rendered are not parallel to the coordinate axes of the world coordinate system. If the spatial coordinates are normalized according to the bounding box of the model to be rendered, the thickness value determined according to the normalized spatial coordinates will be inaccurate.
[0073] Therefore, in the embodiment of the present application, when the target coordinate space is the model coordinate space and the space coordinates are normalized according to the bounding box parameters, the accuracy of the thickness value subsequently determined according to the normalized space coordinates can be improved.
[0074] For example, when the target coordinate space is the world coordinate space and the space coordinates are normalized according to the bounding box parameters, the thickness value determined according to the normalized space coordinates can be as follows: Figure 3 As shown in 301, when the target coordinate space is the model coordinate space and the space coordinates are normalized according to the bounding box parameters, the thickness value determined according to the normalized space coordinates can be as follows Figure 3 As shown in 302, from Figure 3 It can be seen that Figure 3 The range of thickness values shown in 302 is larger, which is more conducive to expressing thickness changes.
[0075] 103. Determine component coordinate values of the normalized space coordinates in a target direction, where the target direction includes at least one of an irradiation direction of the light source to the model to be rendered and an observation direction of the model to be rendered.
[0076] The component coordinate value of the normalized space coordinate in the target direction can be understood as the projection value of the normalized space coordinate in the target direction. The irradiation direction of the light source to the model to be rendered can include the incident direction of the light of the model to be rendered and the transmission direction of the light of the model to be rendered.
[0077] The incident direction of the light of the model to be rendered refers to the direction when the light is incident on the model to be rendered. The transmission direction of the light of the model to be rendered refers to the transmission direction of the incident light of the model to be rendered.
[0078] Since the thickness value of the model to be rendered in the direction of light incidence will affect the light that can be incident on the model to be rendered, thereby affecting the transmission effect of the model to be rendered on the light, when the thickness value in the direction of light incidence is different, the light that can be incident on the model to be rendered is also different, and the light transmission effect of the model to be rendered is also different.
[0079] Since the thickness value of the light incident on the model to be rendered in the transmission direction of the model to be rendered will affect the transmission effect of the light incident on the model to be rendered, when the thickness value in the transmission direction of the light is different, the light transmitted from the model to be rendered may also be different, and the transmission effect of the model to be rendered may also be different. Therefore, the component coordinate value of the normalized spatial coordinate in the illumination direction can be determined, and the thickness value subsequently determined based on the component coordinate value in the illumination direction is the thickness value that the light passes through from the incident on the model to be rendered to the transmission.
[0080] Since the user observes the light transmission effect of the model to be rendered from the observation direction of the model to be rendered, the thickness value of the model to be rendered in the observation direction will also affect the light transmission effect of the model to be rendered felt by the user. When the thickness value in the observation direction is different, the light transmission effect of the model to be rendered felt by the user is also different. Therefore, the target direction can be the observation direction.
[0081] Therefore, in an embodiment of the present application, the component coordinate values of the normalized spatial coordinates in the target direction can be determined, so as to determine the thickness value in the target direction based on the component coordinate values in the target direction, and thus the model to be rendered can be rendered based on the thickness value in the target direction, so that the light transmission effect of the rendered model is closer to the actual situation.
[0082] In some embodiments, the process of determining the component coordinate value of the normalized spatial coordinate in the target direction may be:
[0083] Determine the angle between the vector direction corresponding to the normalized space coordinate and the target direction;
[0084] According to the normalized space coordinate and the cosine value of the included angle, the component coordinate value of the normalized space coordinate in the target direction is determined.
[0085] Alternatively, in some embodiments, the target direction is the irradiation direction, and determining the component coordinate value of the normalized space coordinate in the target direction includes:
[0086] Obtain the illumination vector of the model to be rendered in the target coordinate space, where the direction of the illumination vector indicates the illumination direction;
[0087] Perform dot product processing on the normalized space coordinates and the illumination vector to obtain the component coordinate values of the normalized space coordinates in the target direction.
[0088] For example, the normalized space coordinate is P, and the illumination vector is L, then the component coordinate value T1 = Dot(P, L), where dot represents dot product processing.
[0089] In an embodiment of the present application, the illumination direction is indicated by the illumination vector of the model to be rendered in the target coordinate space, and then the normalized space coordinates and the illumination vector are dot-producted to obtain the projection value of the normalized space coordinates in the target direction. The projection value of the normalized space coordinates in the target direction is the component coordinate value of the normalized space coordinates in the target direction, so that the thickness through which the light passes when it is incident and transmitted from the model to be rendered can be determined subsequently based on the coordinate component values.
[0090] Alternatively, in some embodiments, the target direction is the observation direction, and determining the component coordinate values of the normalized space coordinates in the target direction includes:
[0091] Get the camera vector in the target coordinate space. The direction of the camera vector is the orientation of the virtual camera. The orientation of the virtual camera indicates the viewing direction.
[0092] Perform dot product processing on the normalized space coordinates and the camera vector to obtain the component coordinate values of the normalized space coordinates in the target direction.
[0093] The size of the camera vector can be set according to the actual situation, for example, the size of the camera vector can be (0, 0, 1), or the size of the camera vector can be (0, 1, 0), which is not limited in the embodiments of the present application. The direction of the camera vector is the direction of the virtual camera, and the direction of the virtual camera indicates the direction in which the user observes the model to be rendered, that is, the direction of the virtual camera indicates the observation direction.
[0094] After obtaining the camera vector, the terminal performs dot product processing on the normalized space coordinates and the camera vector to obtain the projection value of the normalized space coordinates in the direction of the virtual camera. The projection value of the normalized space coordinates in the direction of the virtual camera is the component coordinate value of the normalized space coordinates in the observation direction.
[0095] For example, the normalized space coordinate is P, and the camera vector is V, then the component coordinate value of the normalized space coordinate in the target direction is T2=Dot(P, V), where dot represents dot product processing.
[0096] In an embodiment of the present application, a camera vector in the target coordinate space is obtained, the direction of the camera vector is the orientation of the virtual camera, the orientation of the virtual camera indicates the observation direction, and the normalized space coordinates and the camera vector are dot-producted to obtain the component coordinate values of the normalized space coordinates in the target direction, so that the thickness value of the model to be rendered in the direction of the virtual camera can be determined based on the component coordinate values.
[0097] 104. Determine the thickness value of the model to be rendered in the target direction according to the component coordinate values.
[0098] Among them, after obtaining the component coordinate value, the terminal can directly determine the component coordinate value as the thickness value of the model to be rendered in the target direction, or, in order to improve the light transmission effect of the model subsequently rendered according to the thickness value, the component coordinate value can be normalized to obtain the thickness value of the model to be rendered in the target direction.
[0099] Specifically, the process of normalizing the component coordinate values to obtain the thickness value of the model to be rendered in the target direction can be:
[0100] The component coordinate value is divided by the first target value and added to the second target value to obtain the thickness value of the model to be rendered in the target direction.
[0101] Among them, the first target value and the second target value can be set according to actual conditions. For example, the first target value can be 1.732 and the second target value can be 0.5. The embodiment of the present application does not limit this.
[0102] 105. Determine the transmittance of the model to be rendered according to the thickness value, and render the model to be rendered based on the transmittance.
[0103] Among them, the method of determining the transmittance of the model to be rendered according to the thickness value can be set according to actual conditions. For example, the transmittance of the model to be rendered can be determined according to the thickness value through the Beer-Lambert law or the Raman scattering method. The embodiment of the present application is not limited here.
[0104] After obtaining the transmittance, the terminal renders the model to be rendered based on the transmittance, and the rendered model has the light transmission effect.
[0105] It can be understood that the application scenario of the rendered model can be set according to actual conditions. For example, the rendered model can be used in a game scene, that is, the rendered model can be a model in a game scene, or the rendered model can also be used in a video scene, that is, the rendered model is a model in a video. The embodiments of the present application are not limited here.
[0106] In an embodiment of the present application, the spatial coordinates of the model to be rendered in the target coordinate space are obtained, and the spatial coordinates are normalized to obtain the normalized spatial coordinates; the component coordinate values of the normalized spatial coordinates in the target direction are determined, and the target direction includes at least one of the irradiation direction of the light source on the model to be rendered and the observation direction of the model to be rendered; according to the component coordinate values, the thickness value of the model to be rendered in the target direction is determined; according to the thickness value, the transmittance of the model to be rendered is determined, and the model to be rendered is rendered based on the transmittance, so as to determine the transmittance of the model to be rendered according to the thickness value of the model to be rendered in the target direction, so that the model obtained after rendering the model to be rendered based on the transmittance has a light transmission effect, and there is no need to make a thickness map, so as to ensure the art asset production workflow, improve the rendering efficiency, and there is no need to obtain the scene depth, so that it is not affected by the distance between the model to be rendered and the virtual camera, which is convenient for art adjustment, and can support opaque models to have a light transmission effect, thereby reducing rendering overhead.
[0107] In some embodiments, the target direction includes an irradiation direction and an observation direction, the thickness value includes a thickness value in the irradiation direction and a thickness value in the observation direction, and the transmittance of the model to be rendered is determined according to the thickness value, including:
[0108] Correcting the thickness value in the observation direction according to the thickness value in the irradiation direction to obtain a corrected thickness value;
[0109] According to the corrected thickness value, the transmittance of the model to be rendered is determined.
[0110] Among them, since when the target direction is the direction of the virtual camera, only the thickness value of a certain axis is considered, at this time, the light transmission effect of the rendered model on the semi-light-facing surface will be distorted. Therefore, in an embodiment of the present application, the thickness value in the observation direction is corrected according to the thickness value in the irradiation direction to obtain the corrected thickness value. According to the corrected thickness value, the transmittance of the model to be rendered is determined, so that the light transmission effect of the model rendered according to the transmittance is closer to the actual situation, thereby increasing the depth details perceived by the user.
[0111] In some embodiments, the thickness value in the observation direction is corrected according to the thickness value in the irradiation direction, and the method for obtaining the corrected thickness value can be set according to actual conditions. For example, the thickness value in the observation direction is corrected according to the thickness value in the irradiation direction, and the process for obtaining the corrected thickness value can be:
[0112] The thickness value in the irradiation direction and the thickness value in the observation direction are weightedly added to achieve correction processing of the thickness value in the observation direction to obtain a corrected thickness value.
[0113] Alternatively, the thickness value in the observation direction is corrected according to the thickness value in the irradiation direction to obtain the corrected thickness value. The process may also be:
[0114] Get the preset interpolation parameters;
[0115] According to preset interpolation parameters, interpolation processing is performed on the thickness value in the irradiation direction and the thickness value in the observation direction to achieve correction processing of the thickness value in the observation direction and obtain a corrected thickness value.
[0116] The preset interpolation parameters are pre-set parameters, which are adjusted by the artist and can be used to control the performance of light transmission effects. The interpolation processing method can be set according to actual conditions, such as bilinear interpolation or lerp interpolation, which is not limited in the present embodiment of the application.
[0117] When the interpolation process is lerp interpolation, the thickness value in the irradiation direction and the thickness value in the observation direction can be substituted into the following formula for interpolation to obtain the corrected thickness value:
[0118] T=lerp(Dot(P,V),Dot(P,L),k)
[0119] Among them, T represents the corrected thickness value, P represents the normalized space coordinate, V represents the camera vector, L represents the illumination vector, and k represents the preset interpolation parameter.
[0120] In an embodiment of the present application, preset interpolation parameters are obtained, and the thickness value in the irradiation direction and the thickness value in the observation direction are interpolated according to the preset interpolation parameters to achieve correction of the thickness value in the observation direction and obtain a corrected thickness value, so that the transmittance of the model to be rendered is determined according to the corrected thickness value, and the light transmission effect of the model rendered according to the transmittance is closer to the actual situation.
[0121] For example, the transmittance is determined according to the thickness value in the irradiation direction, and the model to be rendered can be rendered according to the transmittance. Figure 4 As shown, the transmittance is determined according to the thickness value in the viewing direction, and the model to be rendered is rendered according to the transmittance to obtain the model as shown in FIG. Figure 5 As shown, according to the corrected thickness value, the transmittance of the model to be rendered is determined, and the model to be rendered is rendered according to the transmittance. Figure 6 shown.
[0122] From the above content, it can be seen that in an embodiment of the present application, the spatial coordinates of the model to be rendered in the target coordinate space are obtained, and the spatial coordinates are normalized to obtain normalized spatial coordinates; the component coordinate values of the normalized spatial coordinates in the target direction are determined, and the target direction includes at least one of the irradiation direction of the light source to the model to be rendered and the observation direction of the model to be rendered, and the thickness value of the model to be rendered in the target direction is determined according to the component coordinate values, and the transmittance of the model to be rendered is determined according to the thickness value, and the model to be rendered is rendered based on the transmittance, so as to determine the transmittance of the model to be rendered according to the thickness value of the model to be rendered in the target direction, so that the model obtained after rendering the model to be rendered based on the transmittance has a light transmission effect, and there is no need to make a thickness map, thereby improving rendering efficiency and requiring no additional rendering overhead.
