Here is a list of known bugs in the latest beta version. There are likely
many errors in it as it is now, but I'll do my best to correct those.
If you are aware of *confirmed* bugs that are not in the list, please post
in a reply to this message a link (in http:// format) to the relevant
message.
If you know that some of the bugs in the list have already been fixed,
please tell me.
To POV-Team members: Is the formatting of the list sufficient?

I think this one was answered by Nathan, it wasn't a bug, just a precision
error.

Not a bug. This is an SOR limitation.

This one looks difficult to fix. :-(

Thanks Nathan, I've removed all the entries except report
"18565 Radiosity with recursion > 1".

Is it clear, what the reason for this is?

What's about the texture_map bug I posted in
http://news.povray.org/povray.beta-test/18535/
On Ron's list of know bugs it was listed:
http://news.povray.org/povray.beta-test/18657/
Maybe it's fixed and I missed the information about it.
So long,
Bonsai

I'd go along with that :-/
I compiled the MegaPoVRay 0.7 unix source using MinGW under WinNT4 sp6.
There was an obvious difference in the rendered output from the
WinMegaPoVRay 0.7 (which seems to give the same output as WinPoVRay
3.5) using the test code I posted - the bright bands are much broader.
This is the same as when you use a single box as the container in my
test scene with WinPoVRay (Mega or 3.5).
So, may there be a compiler quirk? Both of the Win versions are MSVC
compiled (from the Help/About).
Could someone try running the script on a Mac with v3.5 and see whether
the bright bands are wide or narrow?

Not to me ... the two ideas I had about sampling (rotate the local basis
about the surface normal and start the sampling sequence where the last
one left off) seem to be dead ends - neither had any appreciable effect
on the output.
There seems to be a lot of alterations of the radiosity settings at
various stages, changing which also seemed to make no difference in
visual quality.
I don't really understand the use of the radiosity gradients or the
octree enough to tinker with those bits of the code.

Well, I can only hope someone comes up with some good ideas ...
Bye for now,
Mike Andrews.
