A particle system for implicit surfaces reconstruction

This paper presents a particle system which displays implicit surfaces. First, we find a particle as a seed. Initialize all particle positions through the moving and updating of the seed particle. The cotangent force makes particles repel each other. The reprojection of normal vector constrains particles moving on the surfaces. The particle system can finally reach a stable and balance state. The method is also effective on displaying singularity points. The experiments result show the flexibility and efficiency of the particle system.
