I've had a quick look at it, and it seems that
in most cases, the camera is parsed wrong
for the OpenGL preview. Just try some basic
scenes supplied with POV-Ray, like "Woodbox.pov"
and you'll see it yourself.
Otherwise its pretty nice, though the objects being
supported are a little few, and it seems that macros
pose a problem in some cases. Didn't work properly
for my "Architecture Model" image, which you can
download on my homepage listed below. It doesn't
set the camera correct for the preview, as well as displaying
the pyramids wrong.
Still, if those flaws have been corrected, that'd be nice,
but I think this will only become useful when you actually
have the ability to use the OpenGL preview for camera-
setup or animation preview. Right now, I don't expect anyone
to set a camera wrong and attempt a final render...

You can be interested in newer buttons (POV-Ray 3.0 now???) for link available
at http://www.povray.org/community/

Yes, the camera is not supported fully yet.
Basically, only a cam with its up, direction, right
and angle components will work, and even then
there is a slight misregister -- at 800 x 600,
the OpenGL and POV cams are several pixels off.
I will keep working on it, unless someone
beats me to it.

I don't know if that's a macro issue; it looks
like all the objects are being drawn. The pyramids
of course come out as boxes, because everything
but spheres emit bboxes currently. The cam has
a FOV discrpency certainly. If you add an "angle 70"
statement, it will register the wireframe much closer.

I have exporting of POV-Ray scene object bboxes
to LSL (Leveller shape list) files working,
providing a way to visually navigate a POV scene
and quickly generate other camera angles.

Will have the updated code/binary available soon.
