Abstract

It is possible to guide skin construction from the creature’s inner anatomy. This paper introduces a method where is provided the system with bones, a set of muscles and a set of subsidiary organs in order to generate the mesh of the skin. The method generates a set of feature points from the inner anatomy. Then, it projects the feature points on a mirror plane which cuts the creature in the middle. Once in the plane, triangulate and reflect the points and adjust the skin’s mesh inflating it and deflating it until all skin vertices are within some threshold of the underlying anatomy. Finally, fur is generated with offsets calculated from the skin’s mesh.Feature point generation and automatic mesh generation strongly rely on the anatomical knowledge provided to the algorithm. However, it eliminates the need of a preexisting skin mesh. The resulting mesh is consistent with the underlying anatomy.
