(...) I think the original suggestion that we mention that it is in row-major format is valid. I agree that the fact that OpenGL (almost certainly one of the top two most used 3D APIs on the planet) uses column major format is a good reason to (...) (17 years ago, 21-Aug-07, to lugnet.cad)

(...) The "so-what" would be that I, as someone who will eventually read in these files to create OpenGL renderings of them, would expect the matrices to be in column-major order, unless explicitly stated otherwise. Rob (17 years ago, 21-Aug-07, to lugnet.cad)

(...) Umm, so what? LDraw is not, and should not, be dependent on OpenGL. Having worked with transformation matrix in both formats, I find the row-major format much easier to hand-edit than column-major organization. At least for LDraw-type usage (...) (17 years ago, 21-Aug-07, to lugnet.cad)

(...) Is this really what the LDRAW spec is stating? Because that would be contrary to the OpenGL spec, in which the standard ordering of matrices is column-major. So if you have a row like a b c d e f g h That would be interpreted in OpenGL as a e (...) (17 years ago, 21-Aug-07, to lugnet.cad)
