Abstract

Abstract
Usually, 3D models are composed by thousands of polygons. Some times, those representations can be obtained with the same visual quality but with a smaller number of polygons. In this paper, we present a method that reduces the size of 3D textured images based on triangular meshes, keeping the visual quality of the model. We introduced a texture criterion that controls the triangle decimation process. We used a polygonal algorithm of decimation that permits the structured point elimination without carrying out a new triangulation on the point cloud. In order to determine which points must to be removed, we used a 2D Sobel filter on the texture. We show that the algorithm can be used for reducing the load, rendering, transfer and storage times of 3D textured images.
