Just curious, has anyone looked at the speed difference between
MegaPOV and the official POV when rendering my chrome/glass spheres scene?
Since posting the source, I haven't heard anything about it.

I've been working on optimizing MegaPov.
Here are features that caused slowdown even when not in use:
* motion blur (it wasn't too bad, but even a little bit is bad)
* uv mapping - this was the worst
* dispersion
* reflection blur
There are other factors that are also affecting the speed, but I haven't
tracked them all down yet. So far, I've fixed motion blur and uv mapping,
and I'll be fixing the others soon. The next version of MegaPov will be
significantly faster.

This is exactly why I'm not very comfortable with the idea that povray 3.5
would have every little patch anyone has made, no matter how useless it is.
The more features it has, the slower the program will be (even if the feature
is not used).
In my opinion a patch is good if:
a) It does something useful
and:
b) It can't be done with the current implementation, or if it can, it would
be a lot slower than the patch (or take a lot more memory).
This is only my opinion.

Wow, now I can imagine that I have contributed to the POV project in
some way, no matter how small. Thanks!
