I’m currently using succesfully java in eclipse, and using glsl shaders.
I’m trying to replicate a glass effect, and this post seems interesting.
I just don’t understand if (and how) I have to pass a picture (monkey face) to the shader so has to produce the effect on the background.
I would have thought there would be something like
uniform sampler2D texture; (representing background image) uniform sampler2D glass_map; (the monkey face)
Instead, there is :
uniform sampler2D u_normal; uniform sampler2D u_diffuse; uniform sampler2D u_reflection;
Maybe I misunderstood the meaning of the post.
By the way, I only draw 2D things.
Any idea is welcome
