The embodiment of the application provides a real-time illumination simulation method of a mobile game, which is shown in fig. 2 and comprises the following steps:
201. and determining the mobile terminal, and loading a scene map of a target scene where the mobile terminal is positioned.
In recent years, the design of a game scene is more and more realistic, and illumination simulation is required to be carried out in the game scene, whether the game scene is outdoor or indoor, and the effect of the illumination simulation directly influences the authenticity of the game scene. Currently, when performing illumination simulation on a game scene, light source information such as the position, the direction, the color and the like of a light source arranged in the scene is generally determined, and an illumination map and a shadow map of the scene are baked according to the light source information, so that the illumination map and the shadow map are processed, and overall illumination simulation of the scene is realized. However, the applicant realizes that the illumination in many game scenes is real-time, for example, the outdoor natural light is continuously changed along with time, and many models in the scenes are movable, so that the real-time illumination and the movement of the models require finer illumination simulation in the games, but the requirements also require that the running occupied memory of the games is larger, and many games cannot be used as the increase of the running occupied memory, so that the effect of the illumination simulation of the scenes in many games is limited by the memory, the shadow precision of the moving models in the scenes is reduced, the image quality of the scenes is poor, and the reality of the illumination simulation of the moving models is difficult to ensure. Therefore, the application provides a real-time illumination simulation method of a moving model, which is characterized in that whether the entity model can generate indirect light is determined according to the model attribute of the entity model in a target scene, then light source simulation data comprising indirect light data for carrying out illumination simulation on a plurality of entity models is generated through baking treatment of a scene light source, shadows of a moving end in the target scene are drawn by adopting the light source simulation data and the direct light data generated by the scene light source, so that the moving end is subjected to illumination simulation by using corresponding parameters according to the position attribute of the moving end in the target scene, a large number of maps are not required to be drawn for illumination, shadows and the like, the corresponding parameters are selected directly according to the position of the moving end to carry out illumination simulation, the shadow precision of the moving end is not limited by game running memory, the image quality of the scene is improved, and the reality of the illumination simulation of the moving model is ensured.
In order to implement the technical scheme described in the application, a scene map of the target scene needs to be prepared, so that the scene map of the target scene is directly loaded, and corresponding baking processing is performed on the basis of the scene map. The scene map is generated by taking a plurality of entity models included in the target scene as units, can be generated offline, and is a full scene map of the target scene. Specifically, since some game development tools exist currently, such as UE4 (Unreal Engine, illusion 4 engine), the scene map may be LQ LIGHTMAP (light map) generated by the game development tool, and the global illumination baking is performed on the field to be processed, so that in the game development tool, the global illumination in the target scene can be controlled to be finer by selecting the global illumination. It should be noted that, in practice, the technical solutions described in the embodiments of the present application may be implemented by setting a series of parameters in a game development tool, where the game development tool is illustrated as a UE4 in the present application. In addition, in the present application, a mobile terminal is taken as an example for explanation, and the model attribute of the mobile terminal is a dynamic model, that is, the mobile terminal is movable, and all solid models with the model attribute of the target scene being the dynamic model can be used as the mobile terminal to perform illumination simulation by adopting the scheme in the embodiment of the present application.
202. Preset processing parameters are set for a scene light source in a target scene, and model attributes are set for a plurality of entity models in a scene map.
In the embodiment of the application, before the simulated illumination of the target scene is performed, parameters such as a light source, a model and the like in the target scene need to be set in a game development tool. In setting the preset processing parameters for the scene light sources in the target scene, the real-time light sources in the target scene, i.e., directioal Light (directed light) in the game development tool, need to be set to Stationary at baking, and to movable at runtime Movable. There may also be a setting for Cascaded Shadow Maps (waterfall shadow map) in the game development tool, setting Cascaded Shadow Maps to 500 distances, and 2 levels of shadows. Further, for natural Light sources in the target scene, i.e., sky Light in the game development tool, needs to be set to state at baking, state at run-time, sky Light will generate Sky Occlusion (ambient Light mask), sourceType is set to SLS SPECIFIED CubeMap (designated stereoscopic map), i.e., sourceType use SceneCaptureCube (scene capture cube) baking Cubemap after Light baking is completed. In addition, the natural light source can be used in a game development tool for 24 hours with intensity and color modifications. Further, for a Point Light source in a target scene, that is, a Point/Spot Light (Point/Spot Light source) in a game development tool, it is required to be set to Movable and Shadows off (shadow off). In some cases, RECTLIGHT (visual lights) may be present, and RECTLIGHT may be set to Static in the game development tool. Through the above process, the scene light source is determined, preset processing parameters are set for the scene light source, the scene light source comprises a real-time light source, a natural light source and a point light source, and the preset processing parameters indicate whether the scene light source moves and generates shadows when generating light source simulation data. And after the setting of the scene light source parameters is completed, the overlapping degree of the lamplight can be checked in a game development tool, so that the occurrence of excessive dark color in a target scene is avoided.
Then, considering that some larger solid models not only receive illumination brought by a light source in a real scene, but also generate some indirect light, the indirect light is diffusely reflected to other models, therefore, model attributes need to be set for a plurality of solid models in a scene map to determine which solid models generate the indirect light, and which solid models only receive the light and do not generate the light, so that shadows and illumination of the solid models can be processed in a targeted manner later. When setting the model attribute, the principle of compliance is to set a larger model in a scene as a static model, such as mountain stones, buildings, landmark buildings and the like, specifically, the model can be set with human body proportion as a reference, the model with length and width larger than or equal to human body proportion is set as the static model, and the model with length and width smaller than human body proportion is set as the dynamic model, such as grass, small stones and the like. However, in the above-mentioned solid model in the human body proportion or more, there is a solid model of a tree, the solid model of a tree has a large or small size, and the light-shielding ability is far less than that of some mountain stones, buildings, and the like, and the generated indirect light is practically negligible, so that the solid model of a tree needs to be used as a dynamic model as well. In order to treat the entity models of the tree differently, the tree is set as a preset entity type in advance, so that the model attribute is set for a plurality of entity models in the scene map, firstly, the entity type of each entity model in the plurality of entity models is queried, a first entity model with the entity type being the preset entity type is extracted from the plurality of entity models, namely, the first entity model with the entity model being the tree is extracted, and the model attribute of the first entity model is directly set as a dynamic model. And then counting the aspect ratio of a second solid model in the plurality of solid models, and setting model attributes for the second solid model based on the aspect ratio, wherein the second solid model is other solid models except the first solid model in the plurality of solid models.
When setting the model attribute for the second solid model, firstly, a preset model proportion, namely a standard human body proportion, is obtained, and particularly for different scenes, the preset model proportion can change along with the size of the scene. Comparing the aspect ratio with a preset model proportion, and when the aspect ratio is greater than or equal to the preset model proportion, determining that the second solid model is a larger model such as mountain stone and building, and setting the model attribute of the second solid model as a static model. In contrast, when the aspect ratio is smaller than the preset model proportion, the second solid model is determined to be a smaller solid model such as small stones, grass and the like, and the model attribute of the second solid model is set as a dynamic model.
In the practical application process, the materials in the target scene are required to be set, so that the developer can set corresponding materials in the game development tool according to the game development requirement. In addition, when setting the material, it is necessary to individually reinforce the AO (Ambient Occlusion, ambient light shielding) of the material in the scene map, and it is not necessary to use the global object scene.
In the practical application process, some game development tools may not support parameter setting of the diversified environment, so in the embodiment of the application, a configuration file related to the environment setting is provided, the configuration file is written into the game development tool through an editor, is introduced into a catalog of the game development tool, provides additional functions in the game development tool, ensures that no direct sunlight is generated when illumination simulation is performed, and can realize setting of more parameters in the environment based on the additional functions.
203. And generating light source simulation data according to the scene light source of the target scene at the current time, the model attributes of the plurality of entity models and the preset processing parameters.
In the embodiment of the application, since some solid models in the target scene can generate indirect light illumination, such as light generated by reflection, for other solid models after receiving illumination, the indirect light is static light, but the color and brightness of the indirect light still need to be adjusted in real time through material simulation, light source simulation data are generated according to the scene light source of the target scene at the current time, the model attributes of a plurality of solid models and preset processing parameters, the light source simulation data comprise the indirect light data for carrying out illumination simulation on the plurality of solid models, and then the indirect light data are relied on to carry out illumination simulation on the solid models in the target scene.
Specifically, first, baking a scene light source based on preset processing parameters to obtain first indirect light baking data in a map form, wherein the first indirect light baking data is used for performing illumination simulation on solid models with model properties being static models in a plurality of solid models, and the scene light source with preset processing parameters can be obtained by baking the scene light source through a game development tool. And then baking the scene light source, the first indirect light baking data and the solid model with the model attribute being a static model in the plurality of solid models by adopting preset processing parameters to obtain second indirect light baking data in the form of spherical harmonic data, wherein the second indirect light baking data is used for carrying out illumination simulation on the solid model with the model attribute being a dynamic model in the plurality of solid models, and the scene light source with the preset processing parameters can be baked by a game development tool. Finally, the first indirect light roasting data and the second indirect light roasting data are taken as light source simulation data.
It should be noted that the game level ratio is proportional to the unit of the game development tool, 1 unit for 1 cm, and determines how detailed the light calculation is, and a smaller ratio will greatly increase the construction time. Thus, for a giant level, the units of the game development tool may be set to 2 or 4 to reduce the time to build the illumination, the larger the value, the faster the baking. In addition, the number of reflections of GI (Global Illumination ) needs to be set when baking processing is performed, starting from the scene light source. 0 refers to direct illumination only, 1 refers to the first reflection, which takes the longest time to calculate, followed by the 2 nd reflection, and subsequent reflection calculations are not too time consuming. Furthermore, when the proportion of interpolation of Photon is set in the game development tool when computing IRRADIANCE CACHING (irradiation amplitude buffer), the proportion can be set at 66 or 75, so that the detail loss caused by indirect shadow and environmental shielding is avoided while less noise is hidden, and a smooth indirect illumination effect is obtained.
