Texture replacing method based on two dimension image

Abstract

The invention discloses a texture replacing method based on a two dimension image; the method comprises the following steps: calculating each chartlet according to model UV; fusing model normal with texture normal; simulating real photosensitive lines; fusing texture diffuse reflection information; fusing texture highlight information; fusing texture color information; integrally fusing all calculated component including fused color information, diffuse reflection information and highlight information, thus obtaining the replaced texture effect.

Description

technical field [0001] The invention belongs to the field of computer graphics and relates to a texture replacement method based on two-dimensional images. Background technique [0002] It usually takes 20 minutes to render a 3D scene. If the scene is more complex, it may take more time, and every time a set of different materials is replaced, it needs to be re-rendered. For a furniture model The composed interior scene, or the interior design of a newly invented car, needs to be replaced with different materials to see what kind of materials can get good results. But it must be re-rendered every time, so the rendering of the 3D model is an extremely time-consuming thing. [0003] However, there are more and more 3D scene applications, including 3D games, 3D interior decoration, etc., if you can use the results of the previous rendering, and do not require extremely detailed rendering, you can use simple lighting models and basic aesthetics Basic for simple texture replace...
