Hi all,

I'm working on a way to recreate existing landscape using POVRay. I got 
DEM data about the real area (VistaPro DEM data), transformed it to PNG 
image to generate HF and ... everything is working fine :-)

Now, my question is : how can I recreate vegetation or material ?

I'm thinking to create a sort of "image" to map on my HF where I can 
tell to POV :
- Ok, if a pixel in light green, use a grass like texture,
- if it's dark green, it's a tree area,
- if it's blu, use water texture with waves,
- if it's gray, it's granit ...

How can I do it ?

An example is welcome as I'm restarting only to play with Pov after a 
very long time ...

Thanks

Laurent
