Method for controlling mapping effect of three-dimensional model

Abstract

The invention discloses a method for controlling the mapping effect of a three-dimensional model, and the method comprises the steps: setting a plurality of groups of mapping setting parameters for the three-dimensional model, and enabling each group of mapping setting parameters to comprise a color matching parameter, a texture mapping, a feature mapping and an effect type parameter; wherein the enabling degree parameter determines whether to enable a feature map, a texture map or a toning parameter; the effect type parameters determine that the texture map and an existing image on the surface of the three-dimensional model adopt modes such as mixing, superposition, excavation or transparency change, and the type of data expression of the feature map belongs to shadow, height or metallic degree, smoothness and the like; the toning parameters are used for color alteration, mixing weight, brightness and transparency. The display effects of the texture chartlet and the feature chartlet are controlled by using the enabling degree parameter, the effect type parameter and the color matching parameter, the effects of rich colors, shadows, luster, color change and the like are generated, and the method is particularly suitable for DIY of the model chartlet.

Description

technical field [0001] The invention relates to the field of making and displaying three-dimensional models, in particular to a method for controlling textures and effects of three-dimensional models. Background technique [0002] The traditional method of adding textures and setting effects to 3D models is to add a main texture to express the overall color, and add effect textures as needed, such as normal maps for shadow effects, height maps for parallax, and specular reflections. Specular maps, luminous maps that represent luminescence, occlusion maps that represent occlusion, etc. These maps use the same UV, tiling and translation parameters as the main map, and then add a four-square continuous detail texture map and the corresponding normal map as needed. There is another set of tiling and translation parameters, using tiling to reuse detail texture maps to improve the clarity of local textures and reduce the file size of maps. Now some 3D software has certain restric...

Problems solved by technology

In practical applications, in order to create rich effects, sometimes it is necessary to add multiple texture maps and effect maps on the surface of the model, so it is forced to use multiple shaders or divide the model into multiple parts to increase the input bit of the map. This method When moving the texture, it cannot cross parts and consume more computing power; the traditional effect texture and the main texture use the same UV and tiling parameters, which will result in lower definition or larger image files; the traditional detail texture texture and the model already have The texture adopts the color mixing mode, the effect is relatively simple, and there is no special effect such as changing the transparency of the model, digging holes, etc.
