(...) Same here for LDView. LDView always flattens part geometry, and this seems to improve performance enough to be noticed. LDView does use a display list for each part, and a nested display list for each nesting level above that (as long as you (...) (18 years ago, 7-Sep-06, to lugnet.cad.dev)

(...) MPD files don't add that many extra levels... usually only 2, isn't it? Further, the only stacking that generally needs to occur at the mpd level is modification of the modelview matrix, which opengl guarantees a minimum of 32. It's only in (...) (18 years ago, 7-Sep-06, to lugnet.cad.dev)

(...) I tested the performance of, and saw a decent gain from flattening part geometry. (Perhaps 15% in BrickDraw3D for QuickDraw3D or OpenGL.) What this means is that when a part is prepared into a drawing list, it is not a list of calls to (...) (18 years ago, 7-Sep-06, to lugnet.cad.dev)

(...) As far as building instructions go, LPub only provides for unique background color/backdrop for up to four levels. This is about as much as I've ever seen in LEGO building instructions. The renderers take care of nesting within individual part (...) (18 years ago, 7-Sep-06, to lugnet.cad.dev)

(...) Hmm. I use MPD models a lot, there can be several levels of nesting within a single .mpd file, and I have been known to refer to .mpd files from other .mpd files. I'm not sure how deep my nesting of model files goes, but I'd be a little (...) (18 years ago, 6-Sep-06, to lugnet.cad.dev)
