 | | LD-Lite Rotation Matrices? —Mike Walsh
| | | | 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 (...) (23 years ago, 8-May-02, to lugnet.cad)

| | | | | | | Actually I have a very similiar question. I originally had a similiar problem in that LDraw in inherently a Left Handed coordinate system, and my rendering engine needs right handed coordinates. I've figured out a solution that works for me so far, (...) (23 years ago, 8-May-02, to lugnet.cad)

Try one of these, maybe they'll work: -a1,0,-1,-0.5,-1,-0.5,-1,0,-1 -a-1,0,1,0.5,1,0.5,1,0,1 Otherwise, fire up your favorite LDraw file editor, set up a 1-part file (I'd use something like 3626bp01, the minifig head).
