Hi everyone

I wasn't going to post this, but I just saw Norbert Kern's pipetree 
image so it seemed appropriate to post another example of an adaptation 
of one Gilles' excellent macros  (not sure how you post a link to 
another thread but it's in povray.binaries.images).

This uses the makeblade part of mgrass.inc to generate a "pallette" of 
50 blades, then uses the trace() function to arrange them on the surface 
of a lathe-type object (actually a rotation from Moray)

The colours for the grass are taken straight from the irtc winner a few 
months ago:

I've been playing with povray for a couple of months now (when I should 
have been revising for finals :-) and this is my favourite object I've 
made. I'm just not sure what to do with it...

It's very cute! What you should do is try to create an
"Natural Allstars" image. For example, you might model
an entire room, filled with normal objects, but "enhanced"
to natural effect. E.g. walls made of ice/stone, a nice
puffy bed made of clouds etc... The grass-vase is like
combining its actual use with the object itself, so clouds
for the bed (dreaming and sleeping), water for cups or
such...

Now that's a great idea. I'd go for it if I had some clue about how to do
it. (I'm a POV beginner-lurker, you know).

Very nice.

I guess I'm rather new at POV, because I can't figure out how the trace()
macro can be used to 'arrange them on the surface'.  From the POV
documentation:

"This is the macro we call for each pixel we want to calculate. That is, the
starting point of the ray is our camera location and the direction is the
direction of the ray starting from there and going through the "pixel" we
are calculating. The macro returns the color of that pixel."

From this I gather that the trace() macro returns a color.  How can a color
be used to arrange blades of grass on a surface?  I would assume that you'd
need a coordinate and direction or something along those lines, not a
color...  but as I said, I'm rather new at this.  There's probably some
documentation that I've overlooked that explains it but I can't seem to find
it.  Would you please be so kind as to explain it to me, or refer me to the
appropriate section of the documentation?  Thank you.

Sun.

Look at 6.1.4.6. in the docs. The Trace you've
looked at is part of the scripted Raytracer implemented
in POV-SDL.
