Summary of The Invention

In the prior art, the volume fog is generally directly generated through the volume material, the volume fog is attached to the model to generate the volume fog effect, and the whole interaction can only be carried out during the interaction, for example, the model with the volume fog material is directly destroyed or hidden. In addition, in the related art, if the volume fog of the topography of the game scene is to be generated, the volume material and the model corresponding to the topography need to be manufactured in advance, and cannot be generated in a generalized way, if the volume fog effect needs to be reused in a large area, a large amount of manpower is required to be consumed to manufacture the volume fog material and the model of the topography. Moreover, the volume fog in the related art is the whole interaction when the volume fog is interacted, and the volume fog cannot be penetrated, for example, the volume fog is thrown to a ball model, so that only the surrounding volume fog contacted with the ball model in the volume fog is interacted, but the related art cannot realize the regional detail interaction.

Exemplary method

Referring to fig. 2, an embodiment of the present application provides a method for generating a volume fog, and an execution subject of the method for generating a volume fog may be, but is not limited to, a server or a terminal device. The method comprises the following steps:

s101, determining a target game scene of a target volume fog model to be generated.

In specific implementation, the target game scene of the target volume fog model to be generated can be determined according to the requirement, alternatively, the target game scene can be determined directly through input of a user, or the target game scene is selected from a plurality of preset game scenes by the user, and the target game scene is determined according to a selection instruction of the user. Alternatively, the target game scene may be any game scene, for example, the target game scene may be a maze scene inside a game, or a specific scene of a certain area in the game, which is not limited.

S102, determining a volume space corresponding to the target volume fog model to be generated based on the target game scene.

In the implementation, after the target game scene is determined, the volume space corresponding to the to-be-generated target volume fog model can be determined according to the target game scene. When the volume space is specifically determined, the volume space corresponding to the target volume fog model can be determined according to the shape of the target game scene. For example, where a target game scene is a room in a game, the corresponding volumetric space may be the space of the entire room. Optionally, the volume space is used for determining the shape and the size of the finally generated target volume fog model, so that the generated target volume fog model is mutually attached to the terrain of the target game scene, and further the generated target volume fog model can fill the whole target game scene and does not have a mold penetrating phenomenon with the target game scene.

In order to accurately determine the volume space, in some embodiments, determining, based on the target game scene, the volume space corresponding to the target volumetric fog model to be generated specifically includes:

determining a target datum point in the target game scene;

transmitting a plurality of target rays around the target game scene with the target datum point as a center;

obtaining the target positions of collision of the target rays and other virtual models in the target game scene;

the volume is determined based on the target position.

In the implementation, the range of the volume space can be determined in the target game scene through ray detection, and when the emitted rays collide with other virtual models in the target game scene, the maximum extension distance of the target volume fog model in the direction is described until the other virtual models collide, so that the target volume fog model can be ensured not to penetrate through other virtual models. Optionally, the other virtual model mainly refers to other virtual models in the target game scene besides the target volume fog model. For example, the other virtual model may be a wall, roof, tree, etc. in the target game scene. When determining the specific volume space through ray detection, a target datum point is determined in the target game scene, alternatively, the target datum point can be determined according to needs, for example, the center position of the target game scene can be determined as the target datum point, or the target datum point can be determined randomly, which is not limited. And then, taking the target datum point as a center, emitting a plurality of target rays to the periphery in the target game scene, and acquiring target positions of collision of each target ray and other virtual models in the target game scene, wherein the target positions are positions of each boundary of a volume space, and finally, the volume space can be determined according to the target positions, for example, the target positions can be directly connected to form the volume space. The specific number of the plurality of target rays emitted to the periphery can be set according to the need, and generally, the larger the number is, the higher the accuracy of the corresponding generated volume space is. Referring to fig. 5, a schematic diagram of determining a volume space corresponding to a target volumetric fog model to be generated is shown, where the target game scene in fig. 5 is an annular maze, and the corresponding generated volume space is a certain section of terrain of the annular maze.

S103, generating a plurality of preset primitive models in the volume space, and rendering materials of the preset primitive models based on the positions of the preset primitive models in a target game scene.

In the implementation, after the volume space is determined, a plurality of preset primitive models can be generated in the volume space, namely, a final target volume fog model is generated in a mode of filling the preset primitive models, so that after the preset primitive models are prefabricated, various target game scenes can be filled with the preset primitive models, and the purpose of generating the target volume fog model which is attached to various terrains in a generalized mode is achieved. The preset primitive model is a minimum unit model for generating the target volume fog model, optionally, the specific form of the preset primitive model can be set according to needs, for example, the preset primitive model can be a sphere model, a cube model or a model with other shapes. After generating a plurality of preset primitive models, the preset primitive models can be further subjected to material rendering according to the positions of the preset primitive models in the target game scene. Alternatively, the same model may be rendered for all positions of the preset primitive models, for example, all preset primitive models may be rendered white in some cloud volume fogs. In some embodiments, different materials may be given to the preset primitive model according to different positions of the preset primitive model, so that the finally obtained target volume fog model has an gradient color or multiple color effects.

In some embodiments, generating a plurality of preset primitive models in the volume space specifically includes:

randomly generating a plurality of preset primitive models in the volume space;

or sequentially generating a plurality of preset primitive models according to a preset sequence, and overlapping the edge areas of two adjacent preset primitive models.

In the implementation, when generating the plurality of preset primitive models in the volume space, the generating may be performed randomly, or the plurality of preset primitive models may be sequentially generated according to a preset sequence, and a process of specifically generating the plurality of preset primitive models is not limited. Alternatively, when determining the number of the plurality of preset primitive models, the volume of the volume space and the volume of the single preset primitive model may be determined first, and then the number of the plurality of preset primitive models may be obtained by using the volume of the single preset primitive model on the volume ratio of the volume space. After the number of preset primitive models is determined, the preset primitive models may be generated in the volumetric space.

In some embodiments, rendering materials of the preset primitive model based on the position of the preset primitive model in the target game scene specifically includes:

Generating an initial three-dimensional volume fog model with a preset form based on the target game scene;

slicing the initial three-dimensional volume fog model along a preset direction to obtain a sequence frame map; wherein the sequence frame map comprises a plurality of texture maps arranged in sequence;

converting the sequence frame map into a volume map; wherein the volume map comprises spatial coordinates of each of the texture maps;

and rendering materials of the preset primitive model based on the position of the preset primitive model in the target game scene and the volume map.

In the implementation, in order to ensure that the overall material effect of the finally generated target volume fog model meets the expectations, namely is matched with the target game scene. The initial three-dimensional volumetric fog model with the preset shape can be generated based on the target game scene, and it should be noted that the preset shape can be set according to the needs, for example, a cube shape, a sphere shape, or other shapes matched with the game scene. The shape and size of the initial three-dimensional volumetric fog model cannot be directly attached to the target game scene, and the initial three-dimensional volumetric fog model is only used for providing a material reference for the target volumetric fog model, so that the material of the generated target volumetric fog model is similar to or consistent with that of the initial three-dimensional volumetric fog model. Alternatively, the initial three-dimensional volumetric fog model may be generated by a rendering engine in the related art, e.g., a 3dmax, houdini, etc. rendering engine. Optionally, the specific material of the initial three-dimensional volumetric fog model may be determined according to the target game scene, for example, if a volumetric fog released by a smoke bullet is required in the current target game scene, the material of the corresponding initial three-dimensional volumetric fog model is the material corresponding to the smoke bullet release effect.

After an initial three-dimensional volume fog model is generated, slicing the initial three-dimensional volume fog model along a preset direction to obtain a sequence frame map; wherein the sequence frame map comprises a plurality of ordered texture maps, wherein the number of the plurality of ordered texture maps is determined by the number of times the slice is taken, and typically the number of times the slice is taken plus 1 is equal to the number of the plurality of ordered texture maps. Referring to fig. 3, a schematic view of slicing the initial three-dimensional volumetric fog model from top to bottom is shown. Referring to fig. 4, for a sequence of frame maps obtained for a cut, it can be seen that the sequence of frame maps includes a plurality of texture maps arranged in sequence. After a sequence frame mapping is obtained, converting the sequence frame mapping into a volume mapping; wherein the volume map comprises spatial coordinates of each of the texture maps; and then determining the material of each primitive model from the volume map according to the position of the preset primitive model in the target game scene so as to finish the material rendering of the preset primitive model.

Since the normal texture map is a planar map, there is generally only two-dimensional coordinates, and in this embodiment, the three-dimensional space coordinates are achieved by slicing the three-dimensional volume fog model and recording the arrangement order of the slices, with respect to the coordinates in the third direction that can be assigned to the texture map corresponding to each slice.

To accurately convert a sequence frame map to a volume map, in some embodiments, converting the sequence frame map to a volume map specifically includes:

obtaining the target size of the initial three-dimensional volume fog model along the preset direction and the target number of the texture maps in the sequence frame maps;

determining component coordinates of the texture map in the preset direction based on the target size, the target number and the arrangement sequence of the texture map;

determining two-dimensional coordinates of each pixel point in the texture map;

determining spatial coordinates of the texture map based on the two-dimensional coordinates and the component coordinates;

the sequence of frame maps is converted to a volume map based on the spatial coordinates of the texture map.

In practice, the pixel points on the texture map normally have only two-dimensional coordinates, for example, coordinates (x, y), so when converting the sequence frame map into the volume map, it is necessary to determine the coordinates of each texture map in the sequence frame map in the third direction first, that is, on the basis of the two-dimensional coordinates, add the coordinates in the third direction to obtain the three-dimensional coordinates, that is, convert the coordinates (x, y) into (x, y, z). When determining the coordinates of each texture map along the third direction (z axis), the target size of the initial three-dimensional volumetric fog model along the preset direction may be determined first, where the preset direction is the third direction, for example, a certain initial three-dimensional volumetric fog model is a cube, where the cube has three directions of length, width and height in space, and if slicing is performed along the direction of the cube, the target size is the size corresponding to the height of the cube. After determining the target size of the initial three-dimensional volumetric fog model along the preset direction, component coordinates (coordinates of a third direction) of the texture map in the preset direction can be determined according to the target number of the texture maps in the sequence frame map, the target size and the arrangement order of the texture maps. Alternatively, the component coordinates in the preset direction may be determined by the following formula:

Wherein H (k) represents the component coordinates of the kth texture map in the preset direction, X represents the target size, and a represents the target number of the texture maps in the sequence frame map, i.e. the number of slices plus 1.

After determining the component coordinates of the texture map in the preset direction, adding the component coordinates to the two-dimensional coordinates of each pixel point in the texture map, so as to obtain the spatial coordinates (three-dimensional coordinates) of the texture map. It should be noted that, the component coordinates of all the pixel points on the same texture map in the preset direction are the same.

In order to accurately render the material of the preset primitive model, in some embodiments, rendering the material of the preset primitive model based on the position of the preset primitive model in the target game scene and the volume map specifically includes:

determining target position coordinates of each vertex of the preset primitive model based on the position of the preset primitive model in a target game scene;

determining a closest target texture map from the volume map based on the target position coordinates;

determining the color of the vertex after rendering the material from the target texture map based on the target position coordinates;

And rendering the material of the preset primitive model based on the color of the vertex after rendering the material.

In the implementation, since the volume map includes a plurality of texture maps having spatial coordinates, and component coordinates of all pixel points in the same texture map in a preset direction are equal, when determining a color of each vertex of the preset primitive model after rendering a material, determining a target texture map closest to the vertex, and then determining the color of the vertex after rendering the material from the target texture map according to a target position coordinate of each vertex, that is, determining the color of the pixel point corresponding to the target position coordinate in the target texture map as the color of the vertex after rendering the material. And when the color of each vertex of the preset primitive model is determined, finishing the material rendering of the preset primitive model.

S104, generating the target volume fog model based on the primitive model after material rendering.

When the method is implemented, after each primitive model after material rendering is obtained, the target volume fog model can be generated through all primitive models after material rendering. Referring to fig. 6, for a certain generated target volume fog model, where the target game scene corresponding to fig. 6 is an annular maze, the corresponding generated target volume fog model is a section of fog in the annular maze, and it can be seen that the fog in fig. 6 is perfectly fit with the annular maze.

In some embodiments, after generating the target volumetric fog model based on the primitive model after material rendering, the method further comprises:

responding to the target volume fog model to trigger interaction in the target game scene, and determining a target preset primitive model for interaction;

and generating the interaction special effect based on the target preset primitive model.

In the implementation, because the target preset primitive model in the scheme is composed of a plurality of preset primitive models, when interaction is performed, interaction can be performed only with the target preset primitive model with interaction, and therefore regional detail interaction is achieved. Optionally, the interaction includes dissolution interaction, collision interaction, contact interaction, and the like, and specific interaction types can be set according to needs, and the comparison is not limited.

In some embodiments, generating the interaction special effect based on the target preset primitive model specifically includes:

determining an initial state texture and an interaction time curve of the interaction special effect;

and replacing the texture of the material of the target preset primitive model with the initial state texture, and adjusting the initial state texture based on the interaction time curve.

In the implementation, referring to fig. 7 and fig. 8, two different interaction time curves are provided, and the specific interaction time curves may be set according to needs without limitation. After a specific interaction time curve is determined, the texture of the material of the target preset primitive model can be replaced by the initial state texture at the moment of triggering interaction, and then the initial state texture is gradually adjusted according to the interaction time curve, so that other special effects which change along with time, such as recovery or dissipation, can be generated. Optionally, the initial state texture may be determined according to specific interactive content, which is not limited. For example, when the interaction is a dissolution interaction, the initial state texture may be a preset initial dissolution texture, and when the interaction is a collision interaction, the initial state texture may be a preset initial collision texture.

For example, in both fig. 7 and 8, the initial state texture gradually disappears over time. Optionally, in the process that the texture in the initial state gradually disappears along with time, the target preset primitive model can be gradually restored to the original texture, or the target preset primitive model can be directly changed into transparent color gradually, and the specific effect can be set according to the needs, so that the method is not limited.

generating integral deformation in the target game scene in response to the target volumetric fog model; wherein the global deformation comprises a scaling deformation and/or a displacement deformation;

the position of the preset primitive model in the target game scene is redetermined based on the target volume fog model after the integral deformation;

and rendering materials of the preset primitive model based on the redetermined position of the preset primitive model in the target game scene and the volume map.

When the whole target volume fog model is deformed such as displacement or scaling, the position of each preset primitive model in the target game scene can be redetermined, and then the material rendering is carried out on the preset primitive models again through the redetermined position of the preset primitive model in the target game scene and the volume map, so that a new target volume fog model does not need to be manufactured from the head. Optionally, in some embodiments, when the whole target volume fog model is deformed such as displacement or scaling, the spatial coordinates of each texture map in the volume map may be scaled or displaced in an equal proportion while the positions of the preset primitive models in the target game scene are redetermined, so that the whole deformed target volume fog model is still consistent with the initial three-dimensional volume fog model.

According to the method for generating the volume fog, a target game scene of a target volume fog model to be generated is determined; determining a volume space corresponding to the target volume fog model to be generated based on the target game scene; generating a plurality of preset primitive models in the volume space, and rendering materials of the preset primitive models based on the positions of the preset primitive models in a target game scene; the target volume fog model is generated based on the primitive model rendered by materials, and the generated target volume fog model is formed by each preset primitive model, so that regional interaction of volume fog can be realized, and meanwhile, a plurality of preset primitive models are generated in a determined volume space to form an integral target volume fog model, so that the method and the device can be suitable for various game scenes and can be well attached to the terrains of the various game scenes. In addition, the application provides a complete programmed method for generating the fitting topography, so that the manpower consumption for customizing the volume fog fitting the topography is reduced, the fluid operation of the volume fog is not used in the scheme of the application, a large amount of computation caused by the fluid operation interaction of the volume fog is reduced, and the regional volume fog interaction mode is simulated under the condition of not using the fluid algorithm, so that the interaction method of the volume fog with lower consumption is brought.

It should be noted that, the method of the embodiments of the present application may be performed by a single device, for example, a computer or a server. The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the methods of embodiments of the present application, and the devices may interact with each other to complete the methods.
