oF with Metal Compute Shader, is it possible?

Currently, macOS does not support openGL 4.3 so we can’t use compute shader.
So I came up an idea to use Metal shader for calucation and transport the result back to openGL.

Metal compute shader

Does anyone have an experience like this?
We can use OpenGL and Metal API simultaneously, but I’m not sure about the impact of video memory sharing/copying. I found ofxMetal which draws ofBoxPrimitive with Metal texture attached, so it seems possible. I haven’t tried compiling though.

It would be good to say good-bye to Ping-pong shader finally.

my memory is hazy, but I think ofxArKit uses a metal shader internally –

some info on some of the steps of mixing gl and metal



Thank you for the info. Wow, didn’t know this GL on Metal exist.
It even has GLFW support. Incredible.
Negative point is that it has a lot of missing functions.
Have you managed to use GL 4.6 + oF (on macOS)?

It has a Metal shader indeed, Shader.metal is the one.
It seems very helpful as a real-world example how to use Metal together with oF.
I will look into it.
Thank you!

Hey @hrs no I never tried.

Hey thanks all for posting about this! I’ve been wondering about it for quite a while and its been a low priority so I haven’t had a chance to look at it. But its really fun to know that this exists in case I need it some day!
