Revision 219937f by Lukas Toenne (master) March 9, 2015, 14:23 (GMT) |
Fix T43674: Smoke collision does not detect obstacles reliably. The smoke obstacle detection was using a maximum distance for BVH checks to find mesh elements that define boundary cells in the grid. This BVH test was using an arbitrary value of 0.6 cell units. It should be `sqrt(3)*0.5` to account for the maximum possible distance of mesh elements inside a cell. Otherwise some cells that should form the boundary are not detected as such (no closest mesh element found inside the radius), so you get gaps in the smoke obstacle. |
