Discrete texture design using a programmable approach.

Many rendering methods use discrete textures (planar arrangements of vector elements) instead of classic bitmaps. Discrete textures are resolution-insensitive and easily allow to modify the elements' geometry or spatial distribution. However, manually drawing such textures is a time-consuming task. Automating this production is a long-time studied subject. The methods designed for this purpose deal with a difficult tradeoff between the reachable variety of textures and the usability for a community of users.
