Title:

    Screen space decals in Warhammer 40,000: Space Marine

Abstract:


    Traditionally, a decal is drawn as a textured mesh patch duplicated from the underlying geometry. This works most of the time, but often suffers from various problems, such as Z-fighting between the underlying mesh and the duplicated decal mesh and stretched decal textures when the underlying mesh has sparse vertices.
