Volume construction from moving unorganised points
Résumé
We present a recursive method to construct a volume from particles generated by a physically based simulation of a flow field. The particles are scattered in the body of the simulated object giving no explicit information about its surface. We show how to build a surface representation of the non-convex "hull" of a scattered points set. The surface is supposed to enclose all the points and have a minimal volume. The surface that we obtain must maintain the main characteristics of accurate geometrical singularities of the phenomenon during its evolution. We have considered the case of toothpaste running out of a tube. Our method uses a density map to construct an enclosing volume of the generated particles, taking care of local singularities.
