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.
