[Radiance-general] animation format

There are quite a lot of encoders. Imagemagick can do it as well as convert 
between image formats (it even reads radiance pictures). A very powerful tool 
to encode or convert video is ffmpeg, it has support for a lot of file 
formats (e.g. avi, mpg, mpg4, and images) and really lots of codecs (e.g. 
mpg, mpg4 / "divx", ...). You should really take a look at this!

That's how I used the projection:

rpict -vta -vh 360 -vv 360 -vp 0 0 1.6 -vd 1 0 0 octree.oct > image.unf

The result will be not a fisheye, but a view to every angle, 360 degrees 
vertically as well as horizontally. So you might try:

rpict -vta -vh 360 -vv 180 -vp 0 0 3 -vd 1 0 0 octree.oct > image.unf
(angular fisheye)

rpict -vth -vh 180 -vv 180 -vp 0 0 3 -vd 1 0 0 octree.oct > image.unf
(hemispherical fisheye)

But, I think you should simply try what you need, using the different 
projections (that's how I do this ;-) And use man rpict - there is a lot of 
info...

CU, Lars.
