In games we can usually just transpose the inner 3x3 R+S, invert scale and handle translation similarly to get a semi-quick inverse.
- GFK_of_xmaspast 10y agoThis is the difference between matrices that are SO(3) (which have trivial inverses) and matrices that are just GL(n) (which: don't).
- Hydraulix989 10y agoThis. Or you know how to calculate the closed-form inverse a priori like with projection matrices (e.g. gluUnProject).
