Abstract[English]
The systems and methods described herein provide improved texture compression techniques by identifying pixels of a texture that are not used or needed for rendering a three-dimensional model and taking into account the "unused" nature of those pixels. The unused pixels may be identified based on the UV mapping of the texture onto the three-dimensional model. According to one aspect of the invention, the systems and methods described herein may modify a compression method (or compression algorithm) to be used to treat the unused pixels as "wildcards" that may produce any color when decoded (and therefore the most efficiently coded representation can be chosen for such unused pixels). According to another aspect of the invention, the systems and methods described herein may pre-process unused pixels to enable the compression method to work more efficiently.[French]
Les systèmes et les procédés de l'invention fournissent des techniques de compression de texture améliorées par identification de pixels d'une texture qui ne sont pas utilisés ou nécessaires pour rendre un modèle tridimensionnel et prendre en compte la nature "inutilisée" de ces pixels. Les pixels inutilisés peuvent être identifiés sur la base du mappage UV de la texture sur le modèle tridimensionnel. Selon un aspect de l'invention, les systèmes et les procédés décrits dans la présente invention peuvent modifier un procédé de compression (ou un algorithme de compression) à utiliser pour traiter les pixels inutilisés en tant que "jokers" qui peuvent produire une quelconque couleur lorsqu'ils sont décodés (et par conséquent la représentation codée la plus efficacement peut être choisie pour de tels pixels inutilisés). Selon un autre aspect de l'invention, les systèmes et les procédés de l'invention peuvent prétraiter des pixels inutilisés pour permettre au procédé de compression de fonctionner plus efficacement.
