Resumen
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.
