Abstract
We propose an approach for modeling surface details such as scales, feathers, or thorns. These types of cellular textures require a rep- resentation with more detail than texture-mapping but are i nconve- nient to model with hand-crafted geometry. We generate patterns of geometric elements using a biolog- ically-motivated cellular development simulation togeth er with a constraint to keep the cells on a surface. The surface may be defined by an implicit function, a volume dataset, or a polygonal mesh. Our simulation combines and extends previous work in developmental models and constrained particle systems.
