Hey, that's pretty good. And I've never even seen that site. I've actually
had walkthrough/flythrough on my list of possible features for a REALLY long
time. Of course, one could argue that the longer a feature stays on the
possible future list, the less likely it is to ever get implemented :-).
On the other hand, I really do want to implement this particular feature,
and I even have source code from an old project I worked on that does
quaternion-based camera motion. The motion is actually trivially simple,
and doesn't require quaternions; it's the arbitrary rotations that make
quaternions useful. And, while I didn't write the quaternion code in that
project, I used it.

Hehehe. In all seriousness, LDView actually has the start of code to
generate LDraw and LDGLite command lines. I played around with it for
awhile before putting it on the back burner. There's no current menu
hookup, but do a search of the LDView code for LDGLite, and you'll find it.
It's been in there for the last few releases. L3P is also on the to-do
list, but I'll have to do a lot more research first.
If you actually want to see it work, you'll have to uncomment the
ID_VIEW_LDRAWCOMMANDLINE case in the big switch statement in
LDViewWindow.cpp, and also add a menu item with that as its ID.

That would be cool, but it might take a lot of work to make the result look
smooth. Since the frame rate jumps around a lot, the individual camera
points wouldn't represent smooth frame positions. Of course, trying to
smooth it out would presumably keep me busy for even longer :-).

| (...) No need for research, just steal the l3p dumping code from main.c in ldglite. I think I added a lot of comments so I could go back to it later and make changes for the next version of l3p. Don (22 years ago, 5-Aug-02, to lugnet.cad)
