Convert OpenGL fragment Shader to WebGL fragment shader

I have a bast experience with OpenGL and GLSL, and I have implemented the Bitonic Merge Sort in CUDA. Then, I think could do this code without problems

Do you have a specific hardware target in mind or is this a proof of concept on a single hardware setup? Also, any specific issues you've had in converting this over to WebGL or is WebGL just not something you frequently work with? I just want to make sure this is possible, because looking over the merge sort code on the link, it looks like it should be, so I'm wondering if I'm overlooking something. Send me a private message and we can talk over some more details, thanks.

I have GLSL experience and also have knowledge on Javascript. This is what should allow me to complete this project successfully.
