Hi Matthias,
You're a genius. Your method produces a spherical map of the whole scene.
For color and brightness there are some hurdles to take though. Because the
illumination is evaluated instead of the color objects mapped with
illumination maps come out relatively bright while objects that recieve just
ambient light and that are not directly lit come out black.
All this could be overcome by putting up light and textures in a scene
twice: once for ray traced images and once for the VR presentation.
Depending on the scene this may be a lot of work and result in two different
outcomes.
Thanks to the help on this list I now know what I did not know before: I
need a program that will stitch rows of prerendered images together and that
will turn them into something that a quicktime viewer understands. Probably
PTGui.
Thanks for your help,
Frank Bueters
