advanced matrix maths
i was wondering where i can read up on the more complicated matrix/vector maths supported in opendwg. the reason is i am trying to implemet a version of the settorotation(angle, axis, center) and i am having big troubles trying to understand how to apply the center to the matrix above. i have the angle and axis working perfectly, but that center has me stumped.
thanx in advance for your support and help.
cheers
