I would welcome shaders.
I also hope they do not happen, at least for a while.

I am fairly confident that Ken would tell you that he does not
have 1/10th the skills of Ron. (And then he would be boasting).
I also believe that if you rubbed two mirrored spheres
together you would produce an interesting image.
More interesting than the one I would produce, no doubt.
I know that you have made me laugh, more than once,
more than twice.
For this I thank and respect you.
I can say no more.

Am I right if I say :
The required skills to program a shader are almost equal to
the skills required to program a new texture/pattern into the
core Povray code ?
After all, and if I understood well, renderman shaders must
be compiled with an ordinary C++ compiler, and they are -sort of-
dynamically linked to the renderer (who gives some data to
the shader, and get a pixel color or some other data in return).
About UV-stuff, the renderers that have shaders usually have only
a few types of primitives : nurbs, bicubic things,... And we know
that some Pov privitives CAN'T be UV-mapped : julias,...

And I don't have half the skills of Gilles Tran or SamuelT or Mick
Hazelgrove. It's all relative.

Pretty much, yeah. Maybe more, if the trend goes toward self-
antialiasing shaders a'la those that Larry Gritz has made.

Not exactly. They're compiled into bytecode (IIRC) by the shader
compiler, which is not really a C compiler. They're then executed
by the renderer pretty much as you say.

Right. RIB only allows for a small subset of objects with easy UV
mappings. But even some of those objects don't have UV code written
yet in MegaPOV. One could always warn that a shader that expected
uv coordinates wouldn't work properly on a non-UV-enabled object.

I am, of course, joking.

Amateur: one that loves what they do.
Rank: part of the "Rank and File", the common folk.
I hope that you are an Amateur. You will never be rank.

Well, if you did say you weren't half as skilled as I, I'd have to
take issue with it. I'm not that good at actually USING the stuff.
