9.1 Introduction

Physically based animation using point-sampled representations has emerged recently as a promising alternative to conventional finite element simulation. It is inspired by so-called meshless methods, where the continuum is discretized using unstructured point samples. This chapter will demonstrate that such methods perform for a wide spectrum of material simulations including brittle fracture, elastic and plastic deformations, and fluids. Such physical point representations are combined with high-resolution, point-sampled surface geometry. Section 9.2 gives an introduction to meshless finite elements and demonstrates ...
