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 the page). Anyone have a matrix that will turn the
image upside down without rotating it?
I did a search of the lugnet.cad.* hierarchy and while I found lots of
discussion rotation matrices, I didn't find an answer to this question.
Thanks,
Mike

| (...) 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). Set your view to Front. (...) (23 years ago, 8-May-02, to lugnet.cad)
