3.1 Introduction
Scene environments in modern games include a wealth of moving and animated
objects, which are key to creating vivid virtual worlds. An essential aspect in
dynamic scenes is the interaction between scene objects. Unfortunately, many
real-time applications only support rigid body collisions due to tight time budgets.
In order to facilitate visual feedback of collisions, residuals such as scratches
or impacts with soft materials like snow or sand are realized by dynamic decal
texture placements. How
