jit.p.vishnu Apply single force to particles The jit.p.vishnu object takes a Jitter particle systems matrix as input, and applies a specific single force world model to it. In order to do so, it interprets the matrix's planes in a particular way: if the incoming matrix is 5-plane, planes 2-4 are interpreted as 3-dimensional position data (x, y, z); if the incoming matrix is 8-plane, planes 2-4 are considered position data, and planes 5-7 as velocity data (in the 5-plane model, velocity is derived from an analysis of positional change).
