can i use glmultmatrix with center xyz coordinates somehow ? the purpose is to do rotation in centerxyz coords,but onlý centerxyz coords.what would be the best solution for my problem ?
I don’t really know what your problem is, but if you want to rotate a point in R3 around another point in R3 (not (0,0,0)), you must:
substract center point from point which needs to be rotated
rotate point around the origin
add the center point to the point that has just been rotated around the origin.
Hoped that helped
