Art-based rendering of Fur, Grass, and Trees
Whats matter ? Complicated geometry
Mimic Dr. Suesss and Geofferys Hayess
styles (procedural stroke-based textures)
How ? Using graftals !!! Particle systems
L-systems (Alvy Ray Smith 15)

How to control stroke density ? Salisbury et
al. 14 difference images How to provide
temporal coherency ? to give priority to the
graftals drawn at the previous frame
