An embodiment of the present application provides a game scene generation method, as shown in fig. 2A, the method includes:
201. a scene height map of the original game scene is generated.
In recent years, the design of game scenes is more and more vivid, and many outdoor scenes in the game have some weather changes, such as snow days, rain days and the like, so that the experience of a user in the game is more real. When an outdoor scene of a snowy day is rendered, in order to achieve the effect of covering snow on the surface of an object, art drawing is usually required to be performed on a game scene, some maps for representing the snow on the surface of the object are made, and the maps are covered on an entity model of the game scene, so that the effect of covering the snow on the surface of the model is achieved. However, the applicant recognizes that some entity models in a game scene have a shielding relationship, for example, a large tree may shield a part of the ground, ray detection is needed to realize the shielding relationship, the model cannot correctly transmit rays, only function fitting is performed on the model, it is difficult to render a correct game scene, and the game scene lacks realism. Therefore, the application provides a game scene generation method, which generates a scene height map describing the height relationship of a plurality of scene models in an original game scene, creates at least one model local area for each scene model in the original game scene, further adds target scene elements to the original game scene based on the scene height map and the at least one model local area of each scene model to form at least one element area, determines element effect parameters of the element areas, interpolates and writes the element effect parameters into the element areas to generate a target game scene rendered with the target scene elements, so that whether the surface of an entity model is blocked or not and the range of the elements to be covered can be accurately judged according to the scene height map and the model local area, and the corresponding scene elements can be directly added to the entity model according to the indication of the scene height map and the model local area, a large number of maps are not required to be made, the generation efficiency of the scene is improved, the correct game scene is conveniently rendered, and the sense of reality of the generated game scene can be improved.
In order to implement the scheme of the present application, a scene height map of an original game scene needs to be generated, where the scene height map describes a height relationship of a plurality of scene models in the original game scene, and a process of generating the scene height map specifically refers to the following steps one to three:
step one, dividing an original game scene into a plurality of scene blocks according to a preset dividing size.
The preset division size may be the height of a scene block, for example, the preset division size may be 2000 meters, so that the original game scene may be divided into scene blocks of 2000 heights. Assuming that two solid models A and B exist in an original game scene and the preset division size is 2000 m, the original game scene is divided into 10 scene blocks with the height of 2000 m by using a 0-bit starting point of a world coordinate point of the original game scene.
And step two, performing collision detection on each scene block in the plurality of scene blocks in the original game scene to generate a height parameter of each scene block.
Taking any scene block in a plurality of scene blocks as an example to illustrate the generation process of the height parameter: for each scene tile in the plurality of scene tiles, firstly, the scene tile is subjected to collision detection, and a plurality of target collision bodies of the scene tile in the original game scene are determined. Specifically, a Physics.overlayBox function can be called to inquire whether a scene block has a collision volume in the original game scene.
Then, a plurality of target scene partitions in which the plurality of target collision volumes are located are queried, and a first target scene partition and a second target scene partition are determined among the plurality of target scene partitions. The height of the first target scene block is the largest of the plurality of target scene blocks, and the height of the second target scene block is the smallest of the plurality of target scene blocks, that is, the highest scene block and the lowest scene block are determined among the plurality of target scene blocks.
Next, the first target scene block is divided into a preset number of block units, and a target block unit is determined among the preset number of block units, where the height of the target block unit is the largest among the preset number of block units. That is, the highest scene block is continuously divided, for example, the preset number may be 10, and the highest scene block is continuously divided into 10 block units, and the highest block unit is determined as the target block unit in the 10 block units.
And finally, comparing the height of the target block unit with a preset height, and generating a height parameter of the scene block according to a comparison result. Specifically, when the comparison result indicates that the height of the target block unit is smaller than the preset height, it indicates that the height of the target block unit is already lower than the preset height, and therefore, the block height of the first target block which is queried last is returned, a first difference between the height of the first target block and the height of the second target block is calculated, and the height parameter is generated according to the first difference. On the contrary, when the comparison result indicates that the height of the target block unit is greater than or equal to the preset height, it indicates that the height of the target block unit is still higher than the preset height, and the target block unit needs to be continuously divided, so that the target block unit is continuously divided into a preset number of secondary block units, whether the height of the secondary block unit with the highest height in the preset number of secondary block units is smaller than the preset height and the secondary block unit with the highest height is divided is judged until the designated unit with the height smaller than the preset height is determined, a third difference value between the unit height of the designated unit and the height of the second target block is calculated, and a height parameter is generated according to the third difference value. Namely, the division is carried out in a circulating mode until the division finds a unit with the height lower than the preset height, and then the height parameter is generated.
By repeatedly performing the above-described process of generating the height parameter, the height parameter can be generated for each scene block, respectively.
And thirdly, baking the scene models based on the height parameters corresponding to the scene blocks to generate a scene height map of the original game scene.
After the height parameters of each scene block are determined, the multiple scene models can be baked based on the height parameters corresponding to the multiple scene blocks to generate a scene height map of the original game scene, so that the process of generating the height map by partitioning the scene and using collision detection on the scene blocks is realized, and the occlusion relation between the entity models in the original game scene is processed by using the scene height map subsequently.
202. At least one model local area is created for each scene model in the original game scene.
In the embodiment of the present application, since some scene models have self-occlusion relationships, for example, some buildings are designed elaborately, the roof is constructed by a plurality of inclined surfaces, and there are some occlusion relationships between the surfaces, which are the self-occlusion relationships of the scene models. The self-occlusion relationship actually affects the addition of scene elements such as snow accumulation and rain accumulation, so that the scene elements of some surfaces are less or basically not accumulated, in the embodiment of the application, at least one model local surface is created for each scene model in the original game scene, and the self-occlusion relationship of the scene model is baked based on the model local surface, so that the positions of the scene model where the scene elements need to be added and the positions where the scene elements do not need to be added are determined. Specifically, the process of creating at least one model local area surface is as follows:
for each scene model in the original game scene, at least one local area creation parameter is obtained, and the local area creation parameter indicates the direction, the angle and the area of the model local area created for the scene model. Then, at least one model local area is created on top of the scene model according to the at least one local area creation parameter. And respectively creating at least one model local area surface for each scene model by repeatedly executing the creation process of the model local area surfaces. For example, assuming that at least one local area creation parameter indicates that 8 local areas with 30 ° orientation and vertical downward orientation are created on top of the scene model, at least one local area as shown in fig. 2B may be created on top of the scene model according to the at least one local area creation parameter.
203. Adding target scene elements to the original game scene based on the scene height map and the at least one model local surface of each scene model to form at least one element area.
In the embodiment of the application, after determining the scene height map for describing the occlusion relationship between the models and the at least one model local surface for describing the self-occlusion relationship of the scene models, adding the target scene element to the original game scene based on the scene height map and the at least one model local surface of each scene model may be started to form at least one element area.
Specifically, for each scene model of the plurality of scene models, first, a target scene element is constructed on at least one model local area of the scene model, and assuming that the target scene element is a snow particle, a snow particle is constructed on at least one model local area. And then, transmitting the simulated target scene elements to the scene model according to the normal direction of at least one model local area, and controlling the target scene elements to hit the scene model to form at least one initial area. It should be noted that, because the accumulated snow or the accumulated rain of the vertices or the areas of the scene model closer to the sky may be more than the accumulated snow or the accumulated rain of other vertices or the areas of the scene model farther from the sky, when the target scene element is simulated to be transmitted to at least one local surface, the distance between each vertex of the scene model and the local surface may be detected, and the number of the added target scene elements may be controlled according to the distance.
Then, a designated scene block of the at least one initial area in the scene height map is inquired, the block size of the designated scene block is increased to a preset block size in the scene height map, and sampling results of the at least one initial area and the designated scene block with the increased size are detected. The reason why the block size of the designated scene block is increased is that when the particles of the target scene element are located at the boundary of the scene block, different height maps need to be sampled for multiple times to obtain the correct occlusion relationship between the models, so that the block size of the designated scene block is increased, and the designated scene block is expanded. Therefore, when the scene model in the appointed scene block exceeds the appointed scene block, the block and the height map can be directly switched, and the correct shielding relation between the model and the model can be obtained only by sampling one picture. Referring to fig. 2C, the dashed line represents the real division of scene blocks a and B when the block size is not increased, and the left boundary of B after the size is increased is shown in the figure. Finally, since the occlusion relationship between the scene models is determined based on the sampling result of the height map, and the initial region constructed according to the local area surface does not actually consider the occlusion relationship between the scene models, it is necessary to determine the occluded partial region in the at least one initial region according to the sampling result, and remove the target scene element rendered in the partial region in the at least one initial region to obtain at least one element region. The target scene elements of the shielded surface are removed due to the relative relation between the scene models, so that the accumulation of the elements on the surface is avoided, and the condition that the target scene elements accord with the actual natural condition is ensured.
204. An element effect parameter is determined for a plurality of element regions.
In the embodiment of the present application, after a plurality of element regions are determined, since the depth, thickness, range, and the like of elements at each position in a game scene are different, for example, the more obvious the stacking effect of elements in a region closer to the sky of the game scene is, the greater the stacking effect at the bottom of the game scene is than that at the top of the game scene, and the like, it is necessary to determine element effect parameters of the plurality of element regions, and subsequently interpolate the element effect parameters to corresponding element regions. The process of specifically determining the element effect parameters is as follows:
for each element area in the element areas, firstly, a target scene model covered by the element area is determined, the angle difference between the surface normal of the target scene model and the space longitudinal axis is inquired, the area top parameter, the area bottom parameter and the angle difference of the element area are calculated, and the influence degree parameter of the element area is output. Specifically, the influence degree parameter may be output by using a code half level — SnowProgress-level (_ snowtopaddress, _ SnowBottomAmount, saturrate (normalsws. Wherein half level represents the influence degree parameter, snowtopaffect represents the region top parameter, SnowBottomAmount represents the region bottom parameter, and saturrate (normalsws.
And then, determining an area range corresponding to the angle difference, calculating the angle difference and the area range, and outputting an element coverage range of the element area. Specifically, the code half snowRange output element coverage (normal ws. y + _ snowRange) may be used, where half snowRange represents element coverage, normal ws. y represents angle difference, and snowRange represents area range, thereby controlling the influence of normal ws. y on element stacking range based on a snowRange variable.
And then, calculating the influence degree parameter, the element coverage range and the element color data of the target scene element to obtain an element thickness parameter. Specifically, the element thickness parameter may be output using a code half snowHeight left (0.0,1.0, height colorMask height). Wherein half snowHeight represents an element thickness parameter, height represents an influence degree parameter, colorMask represents element color data, and highmask represents an element coverage.
And finally, performing product calculation on the influence degree parameter, the element coverage range and the element thickness parameter to obtain a product result, and calculating a product between the product result and a preset coefficient to serve as an element effect parameter of the element area. Specifically, the element effect parameter may be output using the code half morphvalue level 5.0 snowHeight. Wherein, half lempwvalue represents element effect parameters, snorhrange represents element coverage, level represents influence degree parameters, snorheight represents element thickness parameters, and 5.0 represents a preset coefficient.
By repeatedly executing the above-described process, the element effect parameter can be calculated for each of the plurality of element regions, respectively, to obtain the element effect parameters of the plurality of element regions.
205. And writing the element effect parameter interpolation into a plurality of element areas to obtain a target game scene baked with target scene elements.
In the embodiment of the application, after the element effect parameters are determined, the element effect parameters are interpolated and written into the plurality of element areas, so that the target game scene with the baked target scene elements can be obtained. After determining the interpolation of the element effect parameters, the required Albedo (reflectivity), Smoothness (Smoothness), normal and height may be generated in an element resource library such as a Substance designer according to the element effect parameters, where the a channel of the former is Smoothness and the b channel of the former is height, and the corresponding values of the plurality of element regions may be interpolated.
It should be noted that, when performing interpolation, it is necessary to interpolate to 0.0 the Metallic option in the game development tool, so as to reduce the degree of metallization of the scene model in the interpolated target scene element and avoid distortion of the scene model with excessively high degree of metallization.
206. Indirect light in the target game scene is adjusted.

Specifically, the adjustment of indirect light can be performed in two ways:
the first way is to split indirect light in the target game scene to obtain a reflection coefficient and an illumination coefficient, determine weather color data of scene weather related to the target scene element, calculate a first product of the weather color data and the reflection coefficient, calculate a second product of the element color data of the target scene element and the illumination coefficient, calculate a sum of the first product and the second product, and render scene illumination for the target game scene according to the sum. I.e. the ambient light, which changes in real time at runtime, the Environment Lighting is set to Gradient in the game development tool and the tristimulus values are set to grey values, thus splitting the indirect light into ambient light brightness values reflection coefficients + model surface colors illumination coefficients. And when the system runs, acquiring real-time weather color data, calculating a reflection coefficient and an element color data illumination coefficient of the weather color data as the color of the target indirect light, and performing interpolation rendering of the indirect light by using the variable _ Snowprogress mentioned in the step 204 as an interpolation variable.
The second mode is that the influence degree parameters of a plurality of element areas are determined, indirect light is fitted according to the influence degree parameters to obtain appointed color brightness, and the appointed color brightness is subjected to interpolation rendering to the target game scene. That is, baking with Skybox (sky box) to get the color of the ambient light, and interpolating the indirect light to a specified color brightness according to the stacking degree of the target scene element.
