Abstract

During the using of 3D mesh, the different LOD meshes are needed for a same model. This paper presents an algorithm of 3D mesh reconstructing based on the rendering pipeline. This algorithm bases the pipeline, performs the coordinate transform and records the original coordinates of the mesh during the vertex shader. It interpolates the vertex's 3D coordinates of every pixel in the rasterization. During the pixel shader, it extracts the visible pixels through the depth testing, and then outputs the corresponding 3D coordinates. According to the relative position between the pixels, it connects the 3D vertices together to make a triangle mesh for the current view. The result LOD mesh can be obtained by merging these triangle meshes for different views. The experiments show that the algorithm is effective, speedy and convenient for adjusting the LOD.
