I also got 48, not counting the ones mentioned below.

Well...I've done a lot of work on the scene and include file collections 
for 3.5, and I once released a macro collection, though nobody ever used 
it...

No...if I need that much control of surface features, I generally use 
isosurfaces. ;-)

I think I'll refrain from answering this one...

Nope, I stick to isosurfaces. That count? I think it should...

I've used polynomials of greater than 4th degree in isosurfaces...


Hmm...you know how to do real blurred reflection, you can get the media 
parameters right on the first try (or first few tries), you know the 
difference between using a colored transparent texture and using 
fade_color or media, you can explain why using a mesh is better than a 
union of triangles, you've run into the "patterned textures in layered 
textures" error, you've reached the depth limit in recursive macros, you 
have used the POV-Ray scene description language for purposes which have 
nothing to do with scene description...

You had a hand in creating the current method used to do blurred reflection;

you've run into the "too many layers" error...

...you've gotten past it by creating a single-layered texture that looks just 
like the one you couldn't get with layers...

...you've done that without using a texture_map;

you've used nested pigment_maps; 

you understand what "form" and "metric" do in the 3.5 crackle pattern; 

you understand why, given that A is #declared as a number, (A) and A aren't 
always the same thing; 

you've used 'radial' more than once in the same pigment;

you know all of the options to the repeat warp;

you've used one or more repeat warps to create your own infinitely-tileable 
patterns;

...at least one of those patterns does not appear to be made of rectilinear
regions;

you know how to force the media code to take more samples in an interesting
area of the scene; 

you understand why a plane makes a bad media container;

you know how to use type 5 scattering media; 

you know how to simulate distance-dependent reflection; 

you know how to use .df3 files to create arbitrary full-color solid pigments;

you've used multiple text objects to achieve a desired text effect...

8 :-<  (10 if I take the questions about itrc literally since my best
placing pic was
created in Vue d'espirit)


Warp, I suggest for the questions about top 20 and prize in irtc add the
requirement that the pic must have been created in pov-ray

I think i understand what you mean, so it's clearly a 'Povray internals'
question and not a 'Raytracing in general' one, of course it's perfectly
valid for the list though.

25 now for me (up 10 from 15).

including:

* You know BOTH reasons why a mesh can't be used in CSG.

After all this harcore stuff, 
you actually renderd a complete scene, posted it, somebody even liked it 
and publicly said he uses it as his desktop image.

40

not counting those i have learned meanwhile (like the mesh-CSG question)

You threw out several very nice questions i think, most ones added are not
bad, but generally quite easy, you should give Ron some more room for
improvements... ;-)
