Thermal Vision

im trying to think of a good way to implement thermal/x-ray vision so you can see people threw walls for my "reedemer" type weapon in my game




i have no idea where to start, usally i have at least a basic idea of a way to achieve somthing


but i got nothing

 

How about you put the people on a custom layer, and have another camera that's parented to the main camera render only that layer, and which has a higher depth than the main camera (so it renders on top) and has the clear flag set to depth only?

Yeah, the best approach i think is to have a secondary camera activated when x-ray vision and:

- draw after the main camera
- change the material of the objects to something like solid red to see the shape and not the texture
- add an effect like noise + grayscale (red) to see as with glasses

Good luck

Well.... kindasorta. If someone is near a thin wall and doesn't move around too much, you can see their heat impression on the other side.

 

thank you all very much, i guess i will give the two camera thing a shot

i know that in real life you cant acually see threw things with thermal vision,even glass because it will just show its own temp. but for my game im just going to throw it out there and not explain it haha


how could i have a split screen showing both at once?? like in the bottom corner have what the thermal cam is seeing. and have the rest of the screen show normally.


thanks again for your help, you guys rock

 

Use the same Input to Change Materials?

The same input as switching Cameras: Then have a second set of heavily saturared heat colours and far out shaders? Toggle Materials and Camera?

I was going to explain this, but it was almost as fast just to do it. Plus it was a bit o' fun, so here's a cheesy web player (standard FPS controls, not that there's actually anything to do really), and I attached the project. Basically: three cameras, some fiddling with layers, each "live" object has a duplicate (different materials for each), and a slightly modified alpha diffuse shader (not necessary, but I thought it looked a little better for this purpose).
