Just discovered the OpenGL Preview Patch by Daylon Graphics. Then found 
out that it is a patch for version 3.5 :-(

Anybody know of an OpenGL Preview patch for version 3.6?

It was very interesting idea IMHO, but I think there was no new versions of
it :-/  For wireframe modelling You might use Moray or some other
applications.

I don't want wireframe modelling. I am looking for a wireframe preview 
plugin ^H^H^H^H^H^H add-on ^H^H^H^H^H^H patch ;-) for POV-Ray 3.6 that 
is similar to the OpenGL patch that was available for 3.5.

  AFAIK there isn't such a thing. Even if there were, it would be limited
because not everything can be easily tesselated and represented in
wireframe form.

  One thing you can do is to design your scenes so that each complicated
object can be easily changed to a much simpler shapes for fast previes.
Something like this:

#ifndef(FAST_PREVIEW)
  very complicated object here
#else
  a sphere or two here approximating the object
#end

  This in conjunction with the quality parameter of POV-Ray should help
a lot.

You don't know if there is such a thing at all or you don't know if there is one
for 3.6?

The original patch can be found here:
http://www.daylongraphics.com/other/povray/patches/

Maybe it's best just to e-mail the author and see if he can integrate it into
3.6 like he did with 3.5.

The OpenGL-patch did supporte most objects, some prymitives nativly in
example cone, cylinder, sphere, box, some - like CSG results - by
tesselation. I dont know how about the isosurface.

IMHO, it could be interesting idea to write a plu.. to write a patch that
will allow to convert any object into mesh (and smooth mesh) and
- - use mesh in OpenGL preview
- - use mesh in rendering of very complicated surfaces in complicated scenes
(reflections, radiosity, and so on)
- - save/load mesh  - cach it to disk
- - write it to disk (finally Pov-RAY to mesh-based-programs export :)

The macro mentioned to tesselate arbitrary isosurface perhaps could be
usefull for isosurfaces/CSG, and creating meshes for prymitives should be
easy.

For textures - they could be either normaly used, or pre-calculated to
images, one image per triangle even, with resolution based on size of given
triangle and general LOD (level of details settings).

BTW. is posting PGP signed messages a good idea on news.povray, or is it
rather not wellcomed?

  That has been tried many many years ago, with variable success.
It's nothing new, really.

  I would say they are useless visual noise.

It doesn't have to be very complicated or accurate. Just some wireframes 
(as per the original patch) that show you were things are and how things 
will look before the very long render starts.

Anyway, I didn't want to start a discussion about how it should work or 
wha it should do. I just wondered if a 3.6 compatible version was 
available. Answer: No, it isn't.

  ;-)

Thanks for the input, guys

Searching the web interface of the pov newsgroups for something and having
dozens of the results be matches of sig files with povray SDL is no better.
Happened last night to me when trying to find someone's use of negative
blobs in place of differencing holes in a box. I never did find what I was
looking for.
