 | | LD-Lite Rotation Matrices?
|
| I have been using a matrix (-a-1,0,1,-0.5,-1,-0.5,1,0,1) for rendering upside down images with LD-Lite. It works fine with one issue: The rendered image is also rotated 180 degrees around the Y axis (assuming X horizontal, Y vertical, and Z out of (...) (22 years ago, 8-May-02, to lugnet.cad)
