Hello, I am a TA teaching a povray introduction course (3 weeks of povray)

I just went over the 2.3.4 advanced textures section with them.

I have problems coming up with projects with this section.



What are some of projects that involve some texture maps?

  I don't know if this will help you with any good ideas, but doesn't hurt

I've only come across a few conditions where I've found full texture maps 
necessary (I've found layered textures more common). Texture_maps win 
through for creating smooth textural transitions, such as you get in more 
organic objects, for example, skin texture transitions.

A relatively simple exercise could be to model a snake-like structure with a 
sphere sweep and to use a coarse crackle-based texture on the top and a 
smoother texture on the belly using a gradient texture map to transition 
from top to bottom. Alternatively the skin transition from the back to the 
front of an arm or the top to the bottom of a finger could provide a more 
subtle exercise (using something you can readily lay your hands on).

There are also some non-organic examples: The surface of an old tarmac road 
with transitions where vehicle wheels have left smoothed tracks in the 
surface.  Or a baked earth texture on a plane where patches of hard cracked 
earth show through an otherwise sandy surface.

Regards,
Chris B.
