Interactive free form deformer for point-based objects by GPU acceleration

Abstract

The point-based representation constitutes a recent useful alternative approach for modeling enormous and large 3D polygonal models which contain usually millions of faces. However, and in order to allow the artists and the designers to work with such representation, a new mechanisms of FFD (Free Form Deformation) must be offered and that especially with an interactive response time or real time response (in the best case). This paper presents an acceleration of FFD for point-based objects and particularly splat-based with interactive response time, and that by exploiting the programmable GPU features of the modern graphics cards.
