Texture creation with colorimetric compensation for 3D objects decoration

International audienceThis work takes part in a global industrial project, which aims at decorating 3D plastic objects using Insert Molding technology. Our goal is to compute the decoration of 3D virtual objects, using data coming from polymer film characterization and mechanical simulation. To do this, we introduce a new method to link texture mapping and texture synthesis techniques to a physical process. In the general case of texture mapping, the surface (mesh) adapts the texture through the parameterization. In our context, the mesh comes from a physical distortion of an initial planar mesh, and our goal is to find the texture attached to the initial object, which gives the expected result after distortion. This texture combines informations from several mapped images, which are visible from various views of the 3D objects. Moreover we want the texture mapping to be locally exact for all these views. To achieve this goal, a specific view-dependent parameterization is defined and the inverse transformation is applied to the mesh. Finally we take into account the effects of film distorsion on the texture colors and we compensate these influences during the process of texture creation. Since the industrial project is not finished yet, we validate our process by texturing two simple real objects
