Trying again...
Well, I have incorporated the WyzPOV features into my patch, and added
blurred transparency.
The blurred transparency needs a little work, but is almost ready. The
reflectivity patch is complete, but has a different syntax than
previously planned. The current feature list follows in replies to this
message because I am still having trouble sending long messages.

multiplicative, additive, etc. were removed for now, I am working on
getting them to work
properly. For now, the filter and transmit from pigment are used.

transparence calculations

Patterns:
solid OFFSET Gets the value on the map at position OFFSET.
cloth Just a cloth pigment, similar to two gradients at right
angles mapped with a checker
pattern
cloth2 Returns a value from 0-0.5 for every other square, 0.5-1
for the others.
torspiral TWIST Makes a spiral around a unit sized torus in the xy
plane
pattern_exponent Makes poly_wave obsolete, this is similar but is
applied to waveforms, so
can be used with waveforms like sine_wave. If a pattern_exponent is
applied to a ramp_wave, the result is the same as a poly_wave.

Could you please post a URL or location where the patch resides, is it an
executable, if so what platform, and do you have any example scenes for
the different features ?
Thanks Chris,

eval_pattern(pattern, position) function.
Returns the value of a pattern at a point in space.
#declare value = eval_pattern(crackle, position/< 1, 1, 1>);
eval_pigment(pigment, position) function.
Returns the color of a pigment at a point in space.
eval_warp(warp, position) function.(not finished)
Will return the warped position of a point in space, currently doesn't
work and I am trying to figure out why.
epsilon constant, like pi, smallest number not considered 0.
^ operator for power.
#declare a = b^c;
sqr() and cube() functions
trace() function
vcompare(vectorA, vectorB) function for comparing vectors, returns true
if equal, false otherwise.
noise3d() function

Nope, because it is still in development, although it is almost ready
for release. This is a status update, not an updated version(I suppose I
should have made that more clear, though). When it is finished, I may
just release the source, a Mac version, and give Ron Parker the code to
put in the Superpatch.

Thank you for your clarification.

Chris, I'm already drooling over this feature of your patch. When it's
done can you possibly post some examples in p.b.i.?

Well, I will try...Netscape Communicator has been giving me troubles
with attaching files, the problem is identical to the one which forced
me to split this message into multiple messages. Does anyone know of any
special settings that might be causing the problem? My computer appears
to freeze, but after a couple minutes it gives a message about "socket
not connected".
