hello,

i'm a new user and interesting in using POV to generate a a view that is a
complete 360x180 scene such as the kind that you would use in an IPIX
system.

The desired output from a scene is an image file in equirectangular format,
which is a rectangle twice as wide as it is tall.

the horizontal direction contains the 0-360 degree view (stand and spin
around) and the vertical direction contains the 0-180 direction (look up
and down).

these images are then suitable for direct viewing by a number of VR viewers.

i see that you can generate a spherical view and a cylindrical projection
with the camera, but i'm wondering if you can generate an equirectangular
format directly.

thanks!

JM
