Effectiveness of Ptex method in the field of Texture Mapping and Polygon Topology

This paper presents several texturing problems that occur in complex polygon topology where the model is based on tris and ngons. It also shows an experiment and describes the application of the Ptex system for mapping textures onto a 3D model. The topology parameterization using 3D Coat and its auto-retopology tools are shown as well. A new topology model was tested using a texture checker inside Mudbox and VRay. Additionally, a comparison was made between Mantra and VRay rendering systems, where specific difficulties had occurred when applying Ptex mapping. The aim of this experiment is to present how cache memory directly interferes with texture filtering and rendering speeds. This paper concludes with the advantages and disadvantages observed in relevant literature and through an empirical approach to this technology.
