Dynamic texture mapping is a new method developed at the
Visgraf Project
to overcome
the difficulties on applying bidimensional texture onto implicit surfaces.
Unlike parametric surfaces, implicit surfaces do not have a natural
coordinate system defined on them, and traditional parametric texture
mapping cannot be used.
The method tracks particles associated with the gradient vector field
of the implicit function. The dynamic particle system is used to acquire texture
coordinates in a support object.
