I haven't tried this, but you could apply a texture to a shape in
3DReality, save the result as a RIB file, and study that output for
clues.

The minimal useful call to the texture map shader would be:

	Surface "texmap" "texname" "brick.tx"

Notice that you need the extension on the brick file and that the
extension is tx. RenderMan will complain that it doesn't know the token
"texname" if you do this, so you should declare it:
	Declare "texname" "string"
prior to the call to Surface.

You can compile your own shaders with the "shader" program in
/usr/prman. Doing 'man shader' should tell you all you need to use it.

I'll take the quickies, since I'm about to go home for the evening:

RIB came out after the Companion was published.  Pixar (I believe) still sells  
copies of the RIB spec - it's Rev 3.1 (NeXT is actually sort of 4.0, but it  
shouldn't trip you up much), and I think it costs something like $11.   Pixar  
has moved since it was published, and their new address is:

Pixar
1001 West Cutting
Richmond CA 94804
(510) 236-4000 (voice)
(510) 236-0388 (FAX)

Also, does anyone know how to compile shader function 
> source to a *.slo file?

In a terminal window, for a shader foo.sl, type:

/usr/prman/shader foo.sl

Later.

I suspect that you need to declare the "txmap" variable type-- RenderMan isn't  
going to be able to figure it out by itself.... add something like this to it:

Declare "txmap" "string"
 
(I think it is "string"-- you might have to hack around a moment to figure it  
out)

BTW:  For those interested, pick up the latest release of SmartFieldsPalette  
from the archive sites (the 3.0 version should be available later  
today/tomorrow sometime) and check out the info panel-- it has a 3DReality  
created animation in it.... sort of cool.  Excuse the slowness on opening;  it  
is a jpeg compressed set of TIFF images....
