Revision 74ca67b by Lukas Toenne (hair_system) October 6, 2014, 07:16 (GMT) |
Modification to bending spring calculation to handle the initial direction of the hair curve. Note that bending springs are a bit unstable for low bending stiffness when there is not enough damping. This may be due to missing additional derivatives on the previous segment (dependency of the frame), but calculating these entirely could give a dense matrix instead ... A more practical approach might be to make damping factors relative to the stiffness and set a soft UI minimum of 10% or so. Values much below that are not physically plausible anyway, given that any material has internal friction on bending. |
