Simple Cellular Texturing for Medieval Castles (sap 0238)

Procedurally generated 3d models and textures are becoming ever more important for content-hungry applications such as video games. Previously we reported on procedurally generating medieval castle models from landscape specifications [Colyar and Matthews 2005]. For texturing these castles a Worley cellular texture [Worley 1996] is natural, as each cell in the tesselation can represent a single stone. It has the advantage over 2d textures in that for stones going around complex corners, such as at the crenellations and machicolations surmounting a castle wall, the textures on all sides of the geometry match up [Legakis et al. 2001].
