Description
Technical Field

Background
In games involving snow scenes, it is often necessary to make snow models for the game scenes. Because the weather can change in the game scene, if only the static snow accumulation model is adopted, the snow accumulation on the building always has the same effect no matter how the weather in the game is, no matter whether the weather is heavy snow, light snow or fine, so that the reality sense of a player is brought by the game, and the user experience is improved by adjusting the snow accumulation model when the weather changes.
At present, the adjustment of the snow accumulation model in the game scene mostly adopts the following modes:
in the first mode, snow effects are displayed through a plurality of different models, so that snow scene changes are realized; in this way, although the picture effect is excellent, the amount of data to be loaded is huge, which results in excessive occupation of processor threads, and because the amount of data is large, the model that can be provided is relatively limited, and the dynamic picture is excessively unnatural during switching.
The snow scene change is realized by dynamically and gradually moving the snow accumulation model along the y-axis direction; although the data amount required to be processed by adopting the method is low, a snow scene picture in a game scene is easy to leak, for example, the snow model is directly adjusted on the y axis, although the thickness of snow can be changed along with the change of weather in the game scene, the length-width ratio of the snow model is different from the length-width ratio of other scenes in the game scene due to the fact that the snow model is adjusted only on the y axis, and further the spatial perspective rule of the snow model after being adjusted is not consistent with the spatial perspective rule of other scenes in the game scene. Nor can the designer adjust the model for changes in the amount of snow in the game scene.

Furthermore, the embodiment of the invention not only can accurately control the modeling change of the snow model by research personnel, but also reduces the performance consumption caused by the dynamic change of the snow model, and enhances the game art performance with lower performance cost, thereby improving the user experience.
On the basis of the above-described embodiment, a modified embodiment of the above-described embodiment is proposed, and it is to be noted herein that, in order to make the description brief, only the differences from the above-described embodiment are described in the modified embodiment.
In an optional embodiment of the present invention, the graphical user interface may further include a game scenario, and the step 101 of determining a snow cover adjustment parameter for the snow cover model may include the following steps:
acquiring weather information in the game scene; the weather information comprises temperature and snowfall amount;
determining a snow adjustment parameter for the snow model from the weather information.
In practical application, the graphical user interface of the embodiment of the invention may further include an accumulated snow model, weather information may be preset in a game scene by a game developer in a game development process, the weather information may be temperature, snowfall amount and the like, and the accumulated snow model may change along with changes of the weather information.
In specific implementation, the weather information can correspond to the snow cover adjustment parameters one by one, after the weather information in the game scene is acquired, the snow cover adjustment parameters for the snow cover model can be determined according to the weather information, and the snow cover adjustment parameters can be used for adjusting the snow cover thickness of the snow cover model.
In an optional embodiment of the present invention, before the step of extracting vertex coordinate offset vectors from the vertices of the snow cover model in step 102, the method may further include the steps of:
and subtracting a first vertex coordinate of the vertex of the snow cover model from a second vertex coordinate of the vertex of other snow cover models with the same topological structure as the snow cover model, and solving a vertex coordinate offset vector between the first vertex coordinate and the second vertex coordinate.
Converting the vertex coordinate offset vector to a color attribute format in which to store in vertices of the snow model.
As an example, the topology is the same, which means that the number of vertexes, edges and faces of the snow model is the same as that of other snow models, and the relationship among the vertexes, edges and surfaces is the same, the snow accumulation model can be a high snow accumulation model with the largest snow accumulation thickness in a game scene, the other snow accumulation models with the same topological structure as the snow accumulation model can be low-snow-amount snow accumulation models with snow thickness lower than the snow accumulation model, the embodiment of the invention can respectively obtain the first vertex coordinates of each vertex of the high-snow-amount model and the second vertex coordinates of each vertex of the low-snow-amount model, and can respectively convert the first vertex coordinates of the vertex of the snow accumulation model, and, subtracting second vertex coordinates of vertices of other snow models having the same topology as the snow model, thereby finding vertex coordinate offset vectors, optionally, this step may be done off-line, and its processing for data processing may not be done during game play.
For example, the vertex coordinate offset vector SnowDelta is the first vertex coordinate SnowHigh — the second vertex coordinate SnowLow.
Of course, those skilled in the art may use other algorithms to find the vertex coordinate offset vector, and the embodiments of the present invention are not limited thereto.
In a specific implementation, the embodiment of the present invention may convert the coordinate axis value of the vertex coordinate offset vector X, Y, Z into a three-primary-color attribute format of red, green, and blue R, G, B, so that the xyz value of the vertex coordinate offset vector may be directly stored in the vertex by using the vertex color rgb attribute.
In practical applications, based on the GPU: the GPU of the terminal device needs to read color attributes when rendering the snow model, so that the embodiment of the present invention may convert the vertex coordinate offset vector into a color attribute format, and store the color attribute format in the vertex of the snow model, so that in the rendering for the snow model, the GPU may extract the vertex coordinate offset vector by reading the color attributes in each vertex of the snow model in the vertex.
In an optional embodiment of the present invention, the step 103 of determining the target vertex coordinates through the snow cover adjustment parameter and the vertex coordinate offset vector may include the following steps:
multiplying the accumulated snow adjusting parameter and the vertex coordinate offset vector to obtain a product value;
and adding the product value and the first vertex coordinate to obtain a target vertex coordinate.
As an example, the Shader on the GPU may be used for calculation related to object drawing in real-time rendering, including illumination, deformation, drawing position, drawing manner, and the like, and after extracting the vertex coordinate offset vector, the Shader may multiply the snow cover adjustment parameter and the vertex coordinate offset vector, and add a product obtained by multiplying the snow cover adjustment parameter and the vertex coordinate offset vector to the first vertex coordinate to obtain the target vertex coordinate.
For example, the vertex color SnowDelta is read, multiplied by the global snow adjustment parameter snowPercent, and added to the vertex position vertexPosition of the snow model to calculate the target vertex coordinates: vertexPosition ═ SnowDelta ═ snowPercent + vertexPosition; thus, the vertex deformation calculation of the snow accumulation model is completed, and then the calculated vertex position is continuously used for performing subsequent calculation of the shader. Of course, those skilled in the art may use other algorithms to obtain the target vertex coordinates, and the embodiment of the present invention is not limited thereto.
In an alternative embodiment of the invention, the snow adjustment parameter may be a ratio of a volume of the snow model to a volume of another snow model having the same topology as the snow model. For example, a snow adjustment parameter of an embodiment of the present invention may be a percentage between the volume of the high snow model and the volume of the low snow model.
For example, as shown in fig. 3, fig. 3 is a schematic diagram of an accumulated snow model corresponding to an accumulated snow adjustment parameter, where the accumulated snow adjustment parameter 301 corresponds to a plurality of other accumulated snow models 303 having the same topology as the accumulated snow model 302, and when the accumulated snow adjustment parameter 304 is 100%, the corresponding accumulated snow model 302 is the accumulated snow model with the highest snow amount, the other accumulated snow models 303 have the same topology as the accumulated snow model 302 with the highest snow amount, and when the accumulated snow adjustment parameter 3011 is 20%, the corresponding accumulated snow model 3031 is corresponding to the accumulated snow model 3011, that is, when the snow volume of the current accumulated snow model is 20% of the volume of the accumulated snow model with the highest snow amount, the accumulated snow adjustment parameter 3011 has the corresponding accumulated snow model 3031.
In order to better understand the embodiments of the present invention, a full example will be described below.
1. The original snow model (high snow amount) is copied, the top point of the original snow model is adjusted under the condition of keeping the topological structure of the original snow model, and a new snow model (low snow amount) with less snow is manufactured by research personnel. Therefore, when a research and development worker manufactures a low-snow model, the model design of the model can be completely and accurately controlled, so that the artistic expression effect is optimal, and the situation that the snow model has a leak in a game scene is avoided.
2. The vertex coordinate offset vector for each vertex of the new model (low snow volume) relative to the old model (high snow volume) is recorded in the vertex color. Because the topological structures of the new model and the old model are completely consistent, the vertexes have one-to-one correspondence, the two models only have a slight deformation relationship, and the coordinate deviation value of each vertex is not large. Since the offset values may be represented by three-dimensional vectors and the vertex colors may provide storage space for four-dimensional vectors, which are all floating point numbers float, the xyz values of the vertex coordinate offset vectors may be directly saved in the vertices using the vertex color rgb attribute. In this way, the data of the new model is only extracted from the difference part of the two models and stored in the old model, so that the data content required to be stored is reduced to the maximum extent, the use of system resources is reduced, and the game performance is saved.
3. When the snow accumulation model is rendered, the vertex color stored in advance is extracted from the vertex shader to be used as a vertex coordinate offset vector for increasing or decreasing snow accumulation, the vertex coordinate offset vector is multiplied by a snow accumulation adjusting parameter (which is equal to the percentage from the high snow accumulation model to the low snow accumulation model), and the product is added with the vertex coordinate of the high snow accumulation model, so that the effect of increasing or decreasing snow accumulation can be dynamically obtained. Since the position of the vertex of the computational model in the game scene space is the calculation that the vertex shader must complete, the step only needs to perform a multiplication and then an addition operation before the vertex coordinates are converted from the local space to the game scene space. Due to the structural design of the graphics card GPU, the operation of multiplication and addition can be completed by using one GPU instruction, so that the step only needs to add one instruction in the shader, and the system performance overhead is saved as much as possible.
4. Finally, the change of the weather information in the game is related to the thickness of the snow accumulation model on the building, and the size of the snow accumulation adjusting parameter is dynamically modified when the weather changes, so that the change of the snow accumulation thickness of the snow accumulation model can be controlled by using the variable of the snow accumulation adjusting parameter in the vertex loader of the snow accumulation model.
The embodiment of the invention can acquire the weather information in the game scene when the game is off-line; weather information includes temperature and snowfall amount; determining an accumulated snow adjusting parameter aiming at the accumulated snow model according to the weather information; subtracting a first vertex coordinate of a vertex of the snow accumulation model from a second vertex coordinate of a vertex of another snow accumulation model with the same topological structure as the snow accumulation model, and obtaining a vertex coordinate offset vector between the first vertex coordinate and the second vertex coordinate; the topological structures are the same, namely the number of vertexes, edges and surfaces of the snow accumulation model is the same as that of other snow accumulation models, and the relations among the vertexes, the edges and the surfaces are the same; converting the vertex coordinate offset vector into a color attribute format, and storing the color attribute format in the vertex of the snow cover model; extracting vertex coordinate offset vectors from the vertexes of the snow model; the vertex coordinate offset vector is calculated based on other snow cover models with the same topological structures of the snow cover model and the snow cover model; multiplying the accumulated snow adjusting parameter and the vertex coordinate offset vector to obtain a product value; adding the product value and the first vertex coordinate to obtain a target vertex coordinate; by adopting the mode, the embodiment of the invention can accurately screen the vertex coordinate offset vector corresponding to the weather information by adopting the snow adjusting parameter when the weather information changes in the game process, can render a new snow model by adopting the snow adjusting parameter and the vertex coordinate offset vector, and can calculate the vertex coordinate offset vector when the game is off-line, thereby realizing dynamic change of the snow model when the weather information changes on the premise of not loading a plurality of snow models into a game scene, and meanwhile, the embodiment of the invention can also utilize the characteristic that a GPU needs to read the color attribute to render the snow model, and finish the calculation aiming at the vertex coordinate offset vector when the game is off-line in advance, and the calculation of the vertex coordinate offset vector is stored in the vertex of the snow cover model in advance in a color attribute format, so that the data operation amount in the rendering process is reduced.

Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
