Génération procédurale de textures pour enrichir les détails surfaciques

Abstract : With the increasing power of consumer machines, Computer Graphics is offering us the opportunity to immerse ourselves in ever more detailed virtual worlds. The artists are thus tasked to model and animate these complex virtual scenes. This leads to a prohibitive authoring time, a bigger memory cost and difficulties to correctly and efficiently render this abundance of details. Many tools for procedural content generation have been proposed to resolve these issues. In this thesis, we focused our work on on-the-fly generation of mesoscopic details in order to easily add tiny details on 3D mesh surfaces. By focusing on procedural texture synthesis, we proposed some improvements in order to correctly render textures that modify not only the surface color but faking the surface meso-geometry in real-time. We have presented a methodology for rendering high quality textures without aliasing issues for controllable structured pattern synthesis. We also proposed an on-the-fly normal map generation to disturb the shading calculation and to add irregularites and relief to the textured surface.
