(...) OK, I updated the first "4x4 3D transformation matrix" to now be "4x4 homogeneous transformation matrix". I didn't feel that leaving 3D in there somewhere was practical. Because of this, I intentionally left the text alone two sentences later, (...) (19 years ago, 11-Sep-07, to lugnet.cad)

(...) Yes, the matrix is still homogeneous. In fact this page contains a nifty explanation of how what we normally think of as a translation matrix is actually a shear matrix where the extra w dimension added to make things homogeneous is the fixed (...) (19 years ago, 11-Sep-07, to lugnet.cad)

(...) That's unfortunate (but what I thought I remembered). I didn't have a lot of luck updating the ldliterc.dat file used by the PT. Even after regenerating all the unofficial part images, 58119's image is still incorrect. I'll have to mess with (...) (19 years ago, 11-Sep-07, to lugnet.cad)

Well, I guess being cornered for hours by so many LDraw gurus during the summer prompted me to exert some kind of revenge :-) But of course any Lugnet thread counting more than 20 messages is always worth investigating... Jean-Marc (19 years ago, 11-Sep-07, to lugnet.fun, lugnet.cad)

(...) Before I do that, can someone tell me if a 3D transformation matrix that includes shear is still homogeneous? If not, then I'm not going to put it in. --Travis (19 years ago, 11-Sep-07, to lugnet.cad)

(...) Yeah, it might be time to make the switch. Ldglite has never been updated to use ldconfig.ldr (although it probably wouldn't difficult). It currently only supports the older ldlite config file ldliterc.dat with ldlite COLOR metacommands to (...) (19 years ago, 11-Sep-07, to lugnet.cad, FTX)

(...) That's a good question. The Parts Tracker probably doesn't use ldconfig.ldr, because the image-generator uses a custom script to maintain a combined library of official & unofficial files, which predates ldconfig.ldr. I'm also not sure the (...) (19 years ago, 11-Sep-07, to lugnet.cad)
