I am wondering how to create a refraction effect in the GE. I want to show movement of air with image distortion, similar to a heat wave effect. I’m also wondering if there is a non-GLSL way to accomplish this, as my graphics card is incapable of GLSL renderings. Any answer, non-GLSL or otherwise, is much appreciated! Thanks!
Good luck 
Not that I don’t appreciate your comment, but I think that might be counted as spam, as it really doesn’t contribute to the subject at all.
On the other hand, I also said that if there was a GLSL solution, that would be appreciated as well.
Thanks though.
This would probably require GLSL, and also be computationally-expensive, but I wonder what would happen if you mapped a realtime camera input to a non-flat surface and placed the surface between the main camera and the stuff which needs refracting.
there’s a water refraction blend in the resource section, search for it.
That’s applying distortion to a texture applied to a plane. It isn’t refracting anything.
Regardless if your using GLSL or not, “true” real-time refraction is difficult to pull off. I believe the only way you can pull off real-time refraction (with rasterization), is by adjusting the uv texture (aka: mapping it to your object). I found these article which may be helpful:
Actually, the fake refraction might work well enough, but it the sample file from that thread ran at 16fps.
Thanks for all of your guys’ help!
