Revision 53e624c by Lukas Toenne (gooseberry, gooseberry_farm, hair_immediate_fixes, hair_system, temp_constraint_volume, temp_hair_flow, temp_hair_modifiers, temp_motionpaths) October 31, 2014, 10:59 (GMT) |
Perform grid-based velocity smoothing for hair outside of the implicit solver step. Calculating forces and jacobians from linearly interpolated grid values is problematic due to discontinuities at the grid boundaries. The new approach of modifying velocities after the backward euler solver step was suggested in a newer paper "Detail Preserving Continuum Simulation of Straight Hair" (McAdams, Selle 2009) |
