  1. Hello Charl, a very general question, how to debug GLSL shader codes? any specific tool you use?
    Thanks a lot in advance.

    1. Well hello Changgong, it’s good to see you!

      On the Mac, you can use XCode frame capture to examine all of your buffers, at least for OpenGL ES and for Metal. (I’ve used this for Metal)

      On Windows, I have heard NVidia has a tool that can also help with this, the NSight Visual Studio Edition: https://developer.nvidia.com/nsight-visual-studio-edition-3_0-new-features

      At this very moment on Linux, I’ve set it up so that I can live edit the shaders in question and see the effects in real-time. What I usually do, is send debug values to the fragment shader output and try to understand visually what’s going on as I’m live editing.

      I’m sure there are more elaborate setups, but above is what I have direct or indirect experience with.
