Htex: Per-Halfedge Texturing for Arbitrary Mesh Topologies

We introduce per-halfedge texturing (Htex) a GPU-friendly method for texturing arbitrary polygon-meshes without an explicit parameterization. Htex builds upon the insight that halfedges encode an intrinsic triangulation for polygon meshes, where each halfedge spans a unique triangle with direct adjacency information. Rather than storing a separate texture per face of the input mesh as is done by previous parameterization-free texturing methods, Htex stores a square texture for each halfedge and its twin. We show that this simple change from face to halfedge induces two important properties for high performance parameterization-free texturing. First, Htex natively supports arbitrary polygons without requiring dedicated code for, e.g, non-quad faces. Second, Htex leads to a straightforward and efficient GPU implementation that uses only three texture-fetches per halfedge to produce continuous texturing across the entire mesh. We demonstrate the effectiveness of Htex by rendering production assets in real time

Treball realitzat en el marc d'un programa de mobilitat amb el Karlsruhe Institute of Technology (KIT - University of the State of Baden-Wuerttemberg and National Laboratory of the Helmholtz Association)Se trata de la implementación de un método de texturación por caras en tiempo real que trabaja con "out-of-core textures". Texturas tan grandes que sobrepasan la capacidad de memoria de la GPU. En cuanto a esto se ha trabajado con varias estrategias de caché para ver cuál de ellas funcionaba mejor
