BTW, people said videogames were a fad too. Funny thing is that it's the
industry that drives much of PC's progress today, most notably GPU's. It's been
a pretty long fad so far...

Do you have any actual references to that?

not at hand, Mr. Wikipedia. I remember reading something like that from
people in the industry in the "Game Over" book about old days Nintendo.

Damn, I don't even want to know how many pages you'd have to scroll
through to get to the part that you actually want...

There are these things called "regular expressions" that help with that :)

If you wonder, I recommend reading their code and finding out. Then you
will see how it does not work past spheres and triangles.
If that was sarcastic, then you just managed a branching statement and
you must not be a GPU.

Now I see why the standard reply is so harsh. I have tried, repeatedly,
when this topic comes up to offer actual reasons, enough key words and
phrases that anyone could google for and learn from. Most of the time,
that seems to work. The person who thinks about GPGPU knows enough to
pick out those terms, and find the information themselves. Here, how
ever, we have hit the wall in that it appears nemesis does not want to
know why he is wrong, and only wants to complain. Humor and/or killfiles
are all I have left.

So can I, but what has that to do with whether or not POV is the fastest
raytracer around?

Yes, I'm familiar with the architecture. However, that was one specific
instance of how other programs compromise quality where POV doesn't.
It's not the only way.
Other programs, for instance, also do some or all of the following:
tesselate objects, make liberal use of floats, use fixed textures rather
than procedural, and handle lighting via precomputed lightmaps. This
list is by no means exhaustive nor definitive.
If POV were to accept such optimizations, then it, too, could be made to
run well on upcoming GPUs (I still doubt the current crop would do well).

Interestingly enough, it was crap in the first few and last few pages that I
wanted to change. (I.e., the commands setting up the tables and such.) The
data itself was cool.

Forget "focus follows mouse." When do
