public void SetVirtualParticleIndices(List<uint> indicesIn)

List<uint>

Virtual particles provide more robust and accurate collision handling against collision spheres and capsules. More virtual particles will generally increase the accuracy of collision handling, and thus a sufficient number of virtual particles can mimic triangle-based collision handling. Virtual particles are specified as barycentric interpolation of real particles: The position of a virtual particle is w0 * P0 + w1 * P1 + w2 * P2, where P1, P2, P3 real particle positions. The barycentric weights w0, w1, w2 are stored in a separate table so they can be shared across multiple virtual particles.
