Abstract: A method, apparatus, and article of manufacture provide the ability to map a detail model to a destination while preserving the shape of the detail model. A destination surface (that is a smooth surface) is obtained. The destination surface is tessellated to generate a mesh representation of the destination surface. A parameterization of the mesh representation is then generated. Reverse mapping is conducted from a point of a detail model surface to a point of the destination surface via the parameterization and mesh representation.

Abstract: A system, method, and computer program product are provided for updating texture on a graphical display object with overscan. A preprocessor stage defines an overscan region representing an extension of an object surface rasterized in texture space. A texture update stage creates a dilated texture map that includes updated mapped texels for a mapped region and updated overscan texels corresponding to the overscan region, such that texture is updated in the mapped region and the overscan region. Texel-based and polygon-based preprocessor stages and texture update stages are provided.
