The Design and Realization of Real-Time Texture Mapping and Collage in Virtual Home Decoration

This paper presents the texture mapping algorithm for incomplete and irregular regions in virtual scene. For mapping texture to the incomplete region, the whole region is divided into several discrete subsections and the segmentation textures are kept continuous according to the textures' difference of phases. When mapping texture to the irregular region, the algorithm of convexification and triangularization is adopted. Based on these mapping principles, we provide a new texture collage mapping pattern. To variety of different textures and collage regulations, the rendering to texture technology is used to generate a small geometry texture which will be mapped into the target object based on the texture's structural properties. Besides, the whole texture continuity is also maintained. These algorithm designs have been applied to the Virtual Home Design System. Experimental results have shown these methods can make lots of texture layouts map faster in large-scale also with much lower texture storage space cost.
