Anyone tried to use PovRay for IR or thermal imaging ?

Tx for any help.

Ben.

Salut Ben,

I'm not sure what you want to do exactly. It seems to me that doing IR 
rendering with POVRay is just a question of setting the textures 
according to IR object emission (ie heat) instead of according to the 
classical visible spectrum. If you want to switch between day and night 
textures you might make macros out of your objects with a parameter 
saying which texture should be visible.

I hope that answers your question,

JC

Hmm. POV-Ray is not designed for this. It won't simulate the absorption 
and conduction of heat. It also ignores the wave nature of light, which 
is more important with infrared (longer wavelength). You can simulate 
infrared lighting about as far as you can simulate visible lighting.

If you want something that looks like an infrared photograph, that's 
probably easily possible, just tweak textures and lighting until it 
looks right. If you want a thermograph simulation, that's not possible, 
though you could use POV to visualize the results of an external 
simulation.
