As part of the scanline research, I've got
OpenGL wireframe previewing starting to
work in POV-Ray.

IIRC You can look at Moray for comparison.

I have not read the previous (long) thread but that looks very
promising, and useful .... especially when you have to build a scene and
place objects in it.
Is there any hope that we see a *nix version of your patch ?

Looks promising but how does it show infinite objects (plane, poly),
special shapes (blob, julia_fractal, isosurface) and CSG?
And most important: how does it it invoke OpenGL - i hope in a portable
way so it also works on Mac and Unix.

My question is about storing data necessary for OpenGL preview. How memory
consumption increased (let's say for single tree in gilles macro)? Is memory
allocated only during previewing? Some measurements could be interesting.

I really hope that you made it with system-independent OpenGL code
(eg. by using the GLUT library or whatever).
Since this kind of thing can be done system-independently, it would be
a shame if you made Windows-only code.

To be honest, I realy wonder why this question, in different forms, has
come up a few times now as a reaction to a first try / initial test. As
Ray has stated in several other postings, you all have read, he is fully
aware of the fact that POV-Ray is / should be / stay a platform
independent piece of software. And if, for some reason, it is not platform
independent, I'll hope someone will jump in and help him in making it so.

I'm not using any Win32-specific OpenGL extensions
(I don't even know what they are or if they
even exist, actually).
Considering OpenGL's portability and hardware support,
it's the best choice all around.
Oh, look... DirectX... hmm... (insert evil laugh)

How do you open the window and give the OpenGL library a handle to it?
Certainly the OpenGL library itself has no function to open windows.

Didn't I already mention that the rendercontext
setup/teardown calls are the platform-specific ones that
(unfortunately) did have to be used?
WinPOV has a bunch of Win32-specific modules
to implement the user interface. That's
where the window and its handle comes from.
So this is not just a POV patch, but
a WinPOV patch too.
But by using the existing render window,
I'm minimizing the amount of Win-specific
code added to WinPOV. Otherwise I'd have
to create an HWND, give it a wndproc routine,
destroy it, etc. etc.
