(...) From the standpoint of OpenGL, it uses row-major ordering. There are two ways to draw a transformation matrix. OpenGL uses the following (array offsets shown after): A D G X 0 4 8 12 B E H Y 1 5 9 13 C F I Z 2 6 10 14 0 0 0 1 3 7 11 15 (...) (17 years ago, 22-Aug-07, to lugnet.cad)

| | Portable MPD Submodel Names

Bricksmith and LDView accept descriptive submodel names containing spaces, punctuation, and no file extension. However, I have been given the impression that MPD files containing submodel names like these can be problematic for MLCad and other tools (...) (17 years ago, 22-Aug-07, to lugnet.cad.dev)
