[ODE] Understanding Rotation Matrix

[Joey Coyle]

Thanks

So is this right??

For Matrix

11    12    13
21     22    23
31     32    33

and matrix m

rc  11  =  m[0]
rc  12  = m[1]
rc  13  = m[2]
rc  14 = m[3]  ==  padding set to zero
rc  21  = m[4]
rc  22 = m[5]
rc 23 = m[6]
rc 24 = m[7]  == padding set to zero
rc  31 = m[8]
rc 32 = m[9]
rc 33 = m[10]
rc 34 = m[11]  == padding set to zero

thanks,
joey
