Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of computer, and particularly relates to a virtual fluid model generation method and device, electronic equipment and storage medium. BACKGROUND

[0002] In a computer game scene, in order to make the player better experience the environment in the game and improve the realism of the game, a fluid effect is usually simulated in the game scene, for example, a virtual fluid model with a fluid effect such as a river channel or a pipeline is displayed in the game scene.

[0003] In the prior art, when a virtual fluid model is generated, a virtual fluid model white model is first constructed, vertex coordinates of the virtual fluid model white model in a world coordinate system are calculated, a texture map is sampled through the vertex coordinates, and then mapping processing is performed to obtain a virtual fluid model with a continuous flow effect.

[0004] In the above-mentioned method of generating a virtual fluid model, since the world coordinate system does not rotate, the flow direction of the fluid in the texture map does not change, when the virtual fluid model rotates in the game scene, the vertex coordinates of the virtual fluid model change, while the mapping does not change, which causes the flow direction of the fluid to be wrong after the virtual fluid model is mapped.

[0038] In order for those skilled in the art to better understand the present disclosure scheme, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, not all. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present disclosure.

[0039] Figure 1 A schematic diagram of generating a virtual fluid model in the related art is shown, where the fluid can refer to a non-solid liquid or gas, such as water, oil, magma, etc. In a game scene, the virtual fluid model can refer to a virtual river, a pipeline, etc. which needs to show fluid flow.

[0040] In Figure 1 , the texture Figure 1 is a dynamic image with fluid flow effect, and the texture Figure 1 In the direction F, when generating a virtual fluid model, the related art first constructs a virtual fluid model white model 2, as shown in Figure 1 b, when the virtual fluid model white model 2 is placed in the same direction as the fluid flow direction F in the texture Figure 1 , the texture Figure 1 is sampled and mapped by the vertex coordinates of the virtual fluid model white model 2 in the world coordinate system, and after the mapping, the virtual fluid model after mapping can show the fluid flow effect with the fluid flow direction F.

[0041] However, when the game scene changes or the virtual fluid model is viewed from different game characters, the angle of the virtual fluid model changes, such as Figure 1 As shown in FIG. c of the drawings, the virtual fluid model 2 has an angle θ with the horizontal direction, so that the flow direction F of the virtual fluid model 2 is changed. Figure 1 As shown in FIG. b of the drawings, the vertex coordinates of the virtual fluid model 2 in the world coordinate system are changed, and if the texture is sampled according to the changed vertex coordinates, the texture is not rotated, so that the flow direction of the virtual fluid model 2 after mapping is still the direction F, which causes the flow direction of the fluid to be incorrect in FIG. c of the drawings. Figure 1 Figure 1 Figure 1 Figure 1 Therefore, a large number of texture maps with different flow directions of the fluid need to be maintained.

[0042] Therefore, the embodiments of the present disclosure provide a virtual fluid model generation method, device, electronic device and storage medium, so as to ensure that the fluid is in the correct flow direction when the virtual fluid model is placed at any angle in the game scene.

[0043] Figure 2 A flow chart of a virtual fluid model generation method provided by an embodiment of the present disclosure is provided, and the embodiment can be applied to the case of generating a virtual fluid model in a game scene. The method can be executed by a virtual fluid model generation device, which can be realized in the form of hardware and / or software and can be configured in an electronic device. As shown in FIG. a of the drawings, the virtual fluid model generation method includes the following steps. Figure 2

[0044] S201, determining a target flow direction of a virtual fluid model to be generated in a virtual scene relative to a game character.

[0045] In the embodiment, the virtual scene can be a scene displayed after a game application is run, and the virtual scene can include a game character, a virtual object, a virtual prop, etc. The virtual fluid model is one of the virtual objects, and the virtual fluid model can be a virtual waterway, such as a virtual river. The virtual fluid model can also be a virtual pipeline, such as a virtual oil pipeline or a virtual gas pipeline. In general, the virtual fluid model can be a model simulating the flow effect of a non-solid liquid or gas.

[0046] ​​​​The embodiment can determine a target flow direction of the virtual fluid model to be generated relative to the game character in the virtual scene upon receiving a generation instruction of the virtual fluid model. The generation instruction can be generated by the game application when a preset event is detected. For example, the preset event can be that the game character enters a scene provided with the virtual fluid model. In this case, the generation instruction can be a rendering instruction for the virtual fluid model, which can include the current position and the forward direction of the game character, and can also include the position of the virtual fluid model in the virtual scene. The target flow direction of the virtual fluid model to be generated can be determined based on the current position and the forward direction of the game character. The target flow direction can be the included angle between the flow direction of the fluid in the virtual fluid model and the forward direction of the game character.

[0047] It should be noted that the generation instruction can be generated by the game application and sent to a computer, a mobile terminal or other electronic device. The virtual fluid model is generated and rendered in the electronic device to present the virtual fluid model with a fluid flow effect in the virtual scene displayed on the display screen of the electronic device. Therefore, the target flow direction of the virtual fluid model can also be directly included in the generation instruction.

[0048] As shown in one game scene in Figure 3 , the game character 3 advances along direction A and needs to display a virtual fluid model 2 flowing along direction F. The game application can directly generate a generation instruction including the target flow direction (the included angle between direction A and direction F) and the length (the size along direction F) of the virtual fluid model 2.

[0049] In S202, an original primitive model is created, and a splicing surface and at least one surface to be mapped on the original primitive model are determined based on the target flow direction. The uv coordinates of each surface to be mapped have the same direction.

[0050] The primitive model can be the smallest structural unit constituting the virtual fluid model. The primitive model can be a square model, a cylindrical model, a triangular column, etc. Different virtual fluid models of different geometric shapes can be constructed by different primitive models. The original primitive model can be a white model before mapping.

[0051] Taking the virtual fluid model 2 to be generated in Figure 3 as a square river as an example, the original primitive model can be a cube or a cuboid. After the original primitive model is created, the placement angle of the original primitive model can be determined based on the target flow direction, so as to determine the splicing surface and the surface to be mapped on the original primitive model. The splicing surface can be a surface used for splicing two primitive models. The surface to be mapped can be a surface used for presenting a fluid flow effect. Each surface to be mapped has independent uv coordinates, and the uv coordinates of each surface to be mapped have the same direction.

[0052] AsFigure 4 As shown, Figure 4 In the virtual fluid model to be generated (Figure c), the target flow direction of the fluid is F. The placement angle of the original primitive model can be determined based on the target flow direction. Figure 4 As shown in Figure a, the splicing surfaces and the surfaces to be mapped on the original primitive model can be determined, as follows: Figure 5 As shown, the splicing surfaces of the original primitive model are surfaces P5 and P6, and the surfaces to be textured are surfaces P1-P4. Each of the surfaces to be textured, P1-P4, has a separate uv coordinate system, and the uv coordinates of each surface have the same direction. In this embodiment, the same direction of the uv coordinates can mean that the origin (0, 0) and the endpoint (1, 1) of the uv coordinates are in the same position in the surface. For example, the origin (0, 0) can be the lower left corner of the surface, and the endpoint (1, 1) can be the upper right corner of the surface.

[0053] S203. Obtain a texture map with fluid flow effects.

[0054] In this embodiment, the texture map can be a graphic used to apply textures to the surface of the original primitive model. The texture map can be a dynamic texture including fluid flow effects. In one embodiment, M original texture maps with different fluid flow effects can be obtained. These M original texture maps are then superimposed to obtain texture maps with different flow rates, thereby enhancing the sense of depth in the fluid flow effect through varying flow rates. Of course, those skilled in the art can obtain different texture maps according to the needs of the fluid flow effect. This embodiment does not limit the method of obtaining texture maps with fluid flow effects.

[0055] S204. Based on the UV coordinates of each surface to be mapped, a texture mapping process is used to map the surface to be mapped, resulting in a target primitive model where the fluid flow direction is the same for each surface to be mapped.

[0056] Traditional techniques for texturing 3D models involve unfolding the surface of the 3D model into a 2D plane, and then mapping a texture map to the coordinates of the 2D plane. This allows different areas of the texture map to be mapped onto the various surfaces of the 3D model. The embodiments disclosed herein differ from traditional techniques in that each surface to be textured has independent UV coordinates. These UV coordinates allow a texture map to be completely mapped onto each surface. Figure 5 The texture maps to surfaces P1-P4 shown are each mapped using their respective UV coordinates, giving surfaces P1-P4 a fluid flow effect. Since the UV coordinates are in the same direction, the fluid flow direction on surfaces P1-P4 is also the same. Figure 4 As shown in Figure a, the fluid flow direction on the surface to be mapped is F.

[0057] S205. Several target primitive models are spliced ​​together one by one in the target flow direction through splicing surfaces to obtain a virtual fluid model with the same fluid flow direction as the target flow direction.

[0058] In an optional embodiment, the target size of the virtual fluid model in the target flow direction can be determined first, and the ratio of the target size to the size of the target primitive model can be calculated to obtain the total number K of target primitive models required to construct the virtual fluid model. The K target primitive models are adjusted to the target angle so that the fluid flow direction of the target primitive model is the same as the target flow direction, so as to obtain a virtual fluid model with the same fluid flow direction as the target flow direction by splicing them one by one through splicing surfaces in the target flow direction.

[0059] like Figure 4 In the target element model shown in Figure a, the fluid flows along direction F. Figure 4 In Figure b, the angle attributes of K (four) target primitive models are set to target angles, so that the K target primitive models are arranged according to the target angles of the virtual fluid model. The fluid flow in the K target primitive models is in the same direction, all flowing along direction F. The virtual fluid model is obtained by splicing the K target primitive models together with splicing surfaces, as shown below. Figure 4 As shown in Figure c, the direction of the virtual fluid model obtained by splicing is F. Since the virtual fluid model is generated by splicing the target primitive model, the fluid flow direction in the virtual fluid model is determined by the fluid flow direction in the target primitive model. Virtual fluid models placed at any angle can be generated by splicing the target primitive model, and the fluid flow direction in the spliced ​​virtual fluid model is the same as the fluid flow direction in the target primitive model, ensuring the correctness of the fluid flow direction in the generated virtual fluid model.

[0060] In this embodiment, after determining the target flow direction of the virtual fluid model to be generated relative to the game character in the virtual scene, an original primitive model is created, and based on the target flow direction, a splicing surface and at least one surface to be textured are determined on the original primitive model. The UV coordinates of each surface to be textured have the same direction. A texture map with fluid flow effect is obtained. Further, based on the UV coordinates of each surface to be textured, the texture map is used to process the surface to be textured, resulting in a target primitive model with the same fluid flow direction on the surface to be textured. Several target primitive models are spliced ​​one by one in the target flow direction through splicing surfaces to obtain a virtual fluid model with the same fluid flow direction as the target flow direction. Since the fluid flow direction on the surfaces of the several target primitive models used for splicing is the same, the target flow direction of the fluid can be determined after determining the placement angle of the virtual fluid model. The virtual fluid model is generated by splicing the target primitive models according to the target flow direction, which can ensure the correctness of the flow direction when the virtual fluid model is placed at any angle.

[0061] Figure 6 A flowchart of a virtual fluid model generation method is provided for another optional embodiment of the present disclosure, as shown in Figure 5 The virtual fluid model generation method includes the following steps:

[0062] S601, receiving an instruction for generating a virtual fluid model in a game scene, the instruction including a target position and a forward direction of a game character in the game scene.

[0063] In an optional embodiment, the instruction can be generated when the game application detects a preset event. For example, the preset event can be that the game character enters a scene provided with a virtual fluid model. In this case, the instruction can be a rendering instruction for the virtual fluid model. The instruction can include the target position and the forward direction of the game character in the game scene, and can also include the position of the virtual fluid model in the game scene.

[0064] As shown in a game scene, Figure 3 The game character 3 moves in the direction A. The game application can directly generate an instruction including the position of the game character and the forward direction A.

[0065] S602, determining a target size and a target flow direction of the virtual fluid model to be generated based on the target position and the forward direction.

[0066] Specifically, the target size and the target angle of the virtual fluid model to be generated can be determined based on the target position and the forward direction of the game character. The target size can refer to the length, width and height of the virtual fluid model, and the target flow direction can refer to the included angle between the flow direction of the fluid in the virtual fluid model and the forward direction of the game character. For example, the distance from the game character to the virtual fluid model can be calculated based on the target position of the game character and the position of the virtual fluid model in the game scene. The target size of the virtual fluid model to be presented in the visual angle of the game character can be calculated based on the distance, the forward direction of the game character and the visual angle of the game character. The target size can be the length of the virtual fluid model. The included angle between the flow direction of the fluid in the virtual fluid model and the forward direction of the game character can be calculated as the target flow direction.

[0067] Of course, the target size and the target flow direction of the virtual fluid model can also be directly included in the instruction. The target size and the target flow direction of the virtual fluid model can be obtained by analyzing the instruction, as shown in a game scene, Figure 3 The game character 3 moves in the direction A and needs to display a virtual fluid model 2 flowing in the direction F. The game application can directly generate an instruction including the target flow direction (the included angle between the direction A and the direction F) and the length (the size in the direction F) of the virtual fluid model 2.

[0068] S603. Create an original primitive model with multiple surfaces, and perform UV unwrapping on the original primitive model to obtain a UV unwrapped map including multiple surfaces.

[0069] A primitive model can be the smallest structural unit that constitutes a virtual fluid model. Taking the original primitive model as a cube primitive model as an example, the cube primitive model can be UV-unfolded to obtain a UV-unfolded diagram with six faces, such as... Figure 7 Figure a shows the UV unfolded diagram of the six faces. Figure 7 The UV unfolded diagram shown in Figure a is merely an example. In practical applications, those skilled in the art can adjust the position of each face arbitrarily.

[0070] S604. Based on the target flow direction, determine the target black and white mask map in the pre-configured black and white mask map. The target black and white mask map includes black areas and white areas.

[0071] In this embodiment, the black-and-white mask image can be used to make surfaces in the original primitive model that do not require fluid flow effects transparent. The black-and-white mask image includes black and white areas. Black-and-white mask images corresponding to different flow directions of the virtual fluid model can be pre-configured. The target black-and-white mask image can be determined by the angle range to which the target flow direction belongs. For example, through... Figure 3 The target flow direction of the virtual fluid model 2 that needs to be generated can be found in the pre-configured lookup table of flow direction range and masking map. The target black and white masking map includes black and white areas.

[0072] S605. Use the target black and white masking image to mask the UV unfolded image, determine the surface of the masked black area as the splicing surface of the original primitive model, and determine the surface of the masked white area as the surface to be textured of the original primitive model, and set UV coordinates with the same direction for each surface to be textured.

[0073] like Figure 7 As shown, the UV unwrapping in Figure a corresponds one-to-one with each region of the black and white mask in Figure b. Figure 4 As an example, when two primitive models are joined together... Figure 4 The left and right sides of the primitive model shown in Figure a do not need to have a fluid flow effect as the splicing surface. These two sides need to be masked as splicing surfaces. Assuming the left and right sides are P5 and P6, the target black-and-white mask image is as follows. Figure 7 As shown in Figure b, faces P5 and P6 are masked by black areas, indicating that the left and right sides P5 and P6 are splicing surfaces and need to be made transparent. Faces P1-P4 are masked by white areas as surfaces to be mapped, and texture mapping is required.

[0074] For the four surfaces to be mapped, P1-P4, UV coordinates with the same direction can be set. In this embodiment, the same direction of UV coordinates means that the lower left corner UV coordinate of each of the four surfaces to be mapped is (0,0), the lower right corner UV coordinate is (1,0), the upper left corner UV coordinate is (0,1), and the upper right corner UV coordinate is (1,1).

[0075] S606. Obtain a texture map with fluid flow effects.

[0076] The texture map in this embodiment can be a graphic used to perform texture processing on the surface to be textured of the original primitive model. The texture map can be a dynamic texture including fluid flow effects. In an optional embodiment, step S606 may include the following steps:

[0077] S6061. Obtain M first texture maps with different fluid flow effects.

[0078] The first texture map can be a texture with a fluid flow effect, such as... Figure 8 As shown, the first texture map can be a star map flowing along direction F. M star maps with different flow rates can be obtained as the first texture map. For example, M=3, that is, three star maps with different flow rates are obtained as the first texture map.

[0079] S6062. Obtain the first noise map, and sample the first noise map to obtain the second noise map.

[0080] Specifically, the first noise map can be a randomly generated noise map, such as... Figure 9 The diagram shows the first noise map. After obtaining the first noise map, it is sampled from the first motion direction and the second motion direction to obtain two noise maps after sampling. The first motion direction and the second motion direction can be opposite directions. The two noise maps after sampling are multiplied and mixed to obtain the second noise map.

[0081] For example, the first noise map can be sampled using the sampling function SAMPLE_TEXTURE2D defined within the Unity engine. After defining the first and second motion directions during sampling, the sampling function SAMPLE_TEXTURE2D is run to sample the first noise map, resulting in two sampled noise maps. The two noise maps are then multiplied and mixed to obtain the second noise map. In this embodiment, the final noise map is obtained by sampling the first noise map twice in different directions and then mixing the samples, which can improve the randomness of the noise in the noise map.

[0082] S6063. The M first texture maps are superimposed using the second noise map to obtain M second texture maps.

[0083] Specifically, a second noise map can be superimposed on each first texture map. For example, the second noise map can be superimposed on the uv coordinates of M first texture maps respectively to obtain M second texture maps with a distortion effect.

[0084] S6064. Overlay M second texture maps to obtain a texture map with a fluid flow effect.

[0085] In one embodiment, M second texture maps can be overlaid to obtain a third texture map.

[0086] In another embodiment, after overlaying M second texture maps to obtain a third texture map, the uv coordinates of the third texture map can be transformed to obtain transformed uv coordinates. The transformed uv coordinates are transformed from 0 to -1 to -0.5 to 0.5. The transformed uv coordinates are then graphically represented, and the resulting graphic is multiplied and mixed with the third texture map to obtain a texture map with fluid flow effect and edge brightening effect.

[0087] For example, to obtain a third texture map through overlay processing, abs(i.uv.x-0.5) can be calculated, transforming the uv coordinates of the third texture map from 0 to -1 to -0.5 to 0.5. Then, the transformed uv coordinates are graphically represented, as shown below. Figure 10 The graphic shown has white edges on both sides that gradually turn black towards the center. Multiplying and blending this graphic with a third texture map results in a texture map with fluid flow effects and edge brightening effects.

[0088] In this embodiment, when generating texture maps, on the one hand, a random distortion effect is achieved by superimposing noise maps, which improves the diversity of the flow effect of the generated texture maps. On the other hand, texture maps with different flow rates can be superimposed to obtain texture maps with different flow effects, which increases the sense of layering of the flow effect. Furthermore, highlight edge drawing is achieved through UV conversion graphics. After the original primitive model is textured using texture maps, a highlighting effect can be displayed at the intersection of two adjacent surfaces of the virtual fluid model, which improves the artistic effect of fluid flow.

[0089] S607. For each surface to be mapped, based on the UV coordinates of the surface to be mapped, use texture mapping to process the surface to be mapped.

[0090] Using the original primitive model described above as a cuboid as an example, the four faces P1-P4 are the surfaces to be mapped. Each face has independent UV coordinates, and texture mapping can be performed using their respective UV coordinates. This allows the four faces P1-P4 to have a fluid flow effect, and the fluid flow direction is the same on all four faces. Figure 4 The primitive model in Figure a has four faces (front, top, back, and bottom) with a fluid effect in the direction of flow F.

[0091] S608. Make the splicing surface transparent to obtain a target primitive model in which the fluid flow direction is the same on each surface to be mapped.

[0092] Using the original primitive model as an example, the cube model, P5 and P6 can be made transparent, resulting in a target primitive model where the splicing surfaces are transparent and each surface to be mapped has the same fluid flow direction.

[0093] In this embodiment, before processing the original primitive model with textures to obtain the target primitive model with fluid flow effect, a target black and white mask image can be determined according to the target flow direction of the virtual fluid model. With this target black and white mask image, the surfaces that do not need to have fluid flow effect can be masked as needed according to the arbitrary placement angle of the virtual fluid model, avoiding brightness superposition at the splicing surface when splicing the target primitive model to generate the virtual fluid model, thus improving the artistic effect of the virtual fluid model.

[0094] S609. Calculate the total number of target primitive models using the target size and the size of the target primitive model.

[0095] The size of the target primitive model can refer to the size of the target primitive model in the target flow direction of the virtual fluid model, such as... Figure 4 As shown in Figure a, the ratio of the length of the virtual fluid model to the side length of the cube model can be calculated and rounded up to obtain the total number of target primitive models used to splice and generate the virtual fluid model.

[0096] S610. Adjust the angle of the target primitive model whose quantity equals the total quantity to the target angle, which is the angle when the fluid flow direction of the target primitive model is the same as the target flow direction.

[0097] In this embodiment, the target primitive model has an angle attribute, which determines the placement angle of the target primitive model in the game scene. The angle value in the angle attribute of the target primitive model can be set as the target angle so that the flow direction of the fluid in the target primitive model is consistent with the target flow direction required by the virtual fluid model.

[0098] S611. Multiple target primitive models adjusted to the target angle are spliced ​​together one by one through splicing surfaces to obtain a virtual fluid model with the same fluid flow direction as the target flow direction.

[0099] like Figure 4 In the target element model shown in Figure a, the fluid flows along direction F. Figure 4 In Figure b, the angle attributes of K (four) target primitive models are set to target angles, so that the K target primitive models are arranged according to the target angles of the virtual fluid model. The fluid flow direction in the K target primitive models is the same, all flowing along direction F. The virtual fluid model is obtained by splicing the K target primitive models together. Figure 4 As shown in Figure c, the direction of the resulting virtual fluid model is F, ensuring the correctness of the fluid flow direction. After generating the virtual fluid model, a semi-transparent material is used for rendering. The rendered virtual fluid model is displayed on the screen as follows. Figure 3 As shown, in Figure 3 The fluid flow direction F of the virtual fluid model is consistent with the length direction, ensuring the correctness of the flow direction. Furthermore, the edges of the virtual fluid model are highlighted to better reflect the lighting effects of fluids in reality. In addition, the transparency of the splicing surface is achieved by masking the splicing surface with a black and white mask image, which avoids the brightness superposition at the splicing point of the two primitive models and improves the artistic effect of the virtual fluid model.

[0100] This embodiment can determine the target size and target flow direction of the virtual fluid model to be generated based on the target position and direction of movement of the game character. After performing UV unwrapping on the original primitive model to obtain a UV unwrapped map including multiple surfaces, a target black and white mask map is determined based on the target flow direction in a pre-configured black and white mask map. The target black and white mask map includes black and white areas. The UV unwrapped map is masked using the target black and white mask map. The surface masked by the black area is determined as the splicing surface of the original primitive model, and the surface masked by the white area is determined as the surface to be textured on the original primitive model. UV coordinates with the same direction are set for each surface to be textured, thereby obtaining a fluid-like surface. After applying the texture mapping for the flow effect, the texture mapping is performed on the surface to be mapped based on the UV coordinates of the surface to be mapped, and the splicing surface is made transparent to obtain the target primitive model. Several target primitive models are spliced ​​one by one in the target flow direction through the splicing surface to obtain a virtual fluid model with the same fluid flow direction as the target flow direction. Since the fluid flow direction on the surface of the several target primitive models used for splicing is the same, the target flow direction of the fluid can be determined after determining the placement angle of the virtual fluid model. The virtual fluid model is generated by splicing the target primitive models according to the target flow direction, which can ensure the correctness of the flow direction when the virtual fluid model is placed at any angle.

[0101] Furthermore, by using the black and white masking image determined by the target flow direction, the model-based surface can be masked as needed for different flow directions to determine the splicing surface and make it transparent. This avoids brightness superposition at the splicing surface when using the target primitive model to generate a virtual fluid model, thus improving the artistic effect of the virtual fluid model.
