Revision 4067ab3 by Alexander Gavrilov (master) August 1, 2016, 19:14 (GMT) |
Fix T48991: some particles emitted at a distance from object. The cause seems to be that despite dt_frac being computed as 1/(subframes+1) with integer subframes value, it doesn't always add up to exactly 1.0 due to precision limitations. If the sum is similar to 1.00000???, the last subframe is skipped, and all particles that were supposed to be emitted in that interval are emitted next frame, with the code working incorrectly due to skewed time range. To fix, separate the code from the dynamic timestep feature that adjusts the last subframe length into a separate function, and use it even when dynamic timestep is disabled. |
