Hi,

I'm trying to use a panoramic camera...

camera {
  panoramic
  angle 360
  location <0.12, 0.05, -1.4>
  look_at <0.12, 1.05, -1.4>
}

...but no matter what I set 'angle' to, it doesn't seem to have any
affect on the image produced.  I'm trying to set it to 360, but it
looks more like 180, or maybe even less.

Can you not change the FOV on the panoramic camera?  Or am I just
doing something stupid?

Hope someone can help.

Cheers,

There is a known bug in the panoramic camera code (or a problem with the
docs) - either way, you can't render angles larger than 180 degrees.  If you
want a projection that renders the entire scene in one image, you could use
the spherical camera available in MegaPOV
(http://nathan.kopp.com/patched.htm), or render two 180 degree views using
the panoramic camera (facing in opposite directions) and stitch them
horizontally together.

Aside from what Chris said, with panoramic projection the "angle" keyword must
be the first thing in the camera block in order to have an effect; otherwise the
default angle is used.

If you're interested, Ib Rasmussen wrote a small tutorial about 360
degrees pics.

Hi,

Thanks for all the help guys.  I ended up rendering using a fisheye
camera set to 360 degrees, and using Helmut Dersch's panorama tools
to do the conversion to equirectangular projection. Similar to
Ib Rasmussen's method, but without the need for two renders or any
stitching. (Rasmussen did two renders at 180 degrees)

The results can be seen on my povray page (http://www.xlcus.co.uk/povray/)

These are cool, especially the iridescent dodecahedron in Alien Island.

I thought I had seen the scene from Alien Island somewhere else. Then it hit
me, an older game called 'the Dig' by Sierra On-line. The only things
missing are the light bridges. Great job.

Yep.  The dig was excelent.  One of my favourite games.  I just had
to do a render in tribute.

I did have a go, but I could never get them looking as good as I
wanted, so in the end I just left them out.

Thanks :)
