A Fast Particle System Framework for Interactive Implicit Modeling

In this paper, we present a controllable, fast and efficient particle system framework for skeletal implicit surfaces defined by the BlobTree model. We propose efficient algorithms for generating sets of particles for every type of skeletal element and for combining those sets for warping, blending and Boolean nodes. Given a target level of detail, our system generates particles which are distributed uniformly over the implicit surface. Our incremental approach lends itself to interactive editing of complex models
