Issue Description

rs-gl, When do I want to use it?

I'm deep into the sdk code at this point and I know what I want to do (I already did some of it in the old kinect platform) but I have some big gaps in my knowledge about the low level stuff.
I need to take a frame , analyze the depths, render and show a texture related to the depth values. I need to do this quickly because ,ideally, it is live feedback reading "fast" motion (we'll see how fast is allowed).

I'm wondering if it worthwhile for me to utilize the gpu as per the rs-gl code ? Would this be something to learn?

Hi @arothenberg The link below has a very good pros and cons analysis of GLSL processing blocks and when it can be used.

That helped. It looks easy to implement so I might as well try it and benchmark it. Thanks Marty.
