Hi:

You can't record a perfly walkthru as a movie in realtime, because to save a
frame as a single image takes a lot of time. But you can save your viewpoint
positions for every frame you render, e.g. 30 times a second, in a file.
After recording the positions of your walkthru, you can read your file, then
step through your viewpoint positions. For each position you render the
frame and save it with pfuSaveImage. This way you can create a numbered
image sequence, which you can convert in a Quicktime movie file by using
SGI's mediaconvert. For a QuicktimeVR file, I think you should convert your
image files into the tif or gif format and use Apple's QuickTime VR
Authoring Studio, but I'm not sure.

Hope this helps

Wilfried
