Re: [Algorithms] Thermal infrared techniques?

[<lo...@fr...>]

Hello, 

can't you just use grayscale textures that represent body heat + some 
fancy pixel shader to get the result you want ? It should be decent 
enough to be acceptable (but will require you to use another set of 
textures). If you want to get some reference images, I believe that 
some Sony camera and recorders have IR sensors. 
(see http://www.maxmax.com/camcorders.htm).

BTW, what kind of effect to you want to get ? An colorized image like
http://www.jenoptik-los.com/img/323/1/hauptbild.30.bmp or a grayscale, 
possibly greenish image like 
http://www.dreamshine.com/images/MaxMax/Sam%20Outcalt/NFF_ir_1.JPG 
(difficult to see, but the reason why leaves are so bright is because 
they are warmed by the sunlight; the trunk is less hot. I believe 
this picture has been taken during the day, which would explain the
general bright tone) ?

Objet: [Algorithms] Thermal infrared techniques?

Anyone have points to papers/tutorials/explanations of some algorithms 
for rendering a scene as it would appear through a thermal IR camera?  
As in military operations stuff.  Anything ranging from "good enough" to 
a decent approximation of reality is usable.

Thanks!
