COMPRESSING MATERIAL AND TEXTURE ATTRIBUTES FOR TRIANGULAR MESHES

A novel scheme for single-rate compression of material and texture attributes for triangular meshes is proposed in this work. For the material coding, it proposes a novel approach based on breadth-first surface traversal, exploiting the local coherence of the material attributes among neighboring facets; for the texture coordinate coding, it proposes a similar-triangle-based prediction method, exploiting the correlation between 3D geometry and its texture-space parameterization. As a result, the proposed algorithm achieves efficient coding of the material and the texture attributes, as experimentally demonstrated.EICPCI-S(ISTP)wgp@pku.edu.cn; wuyz145@gmail.com; sulepluto@gmail.com; jpeng@sdu.edu.cnSeptmber2014-Septembe
