Hi, I have an app based on Metal and it runs on VisionOS.
It has a huge sphere mesh and renders video outputs (from AVPlayer) on it.
What I want to do is rendering left portion of my video output on left eye, and right portion of my video output on right eye.
In my fragment shader, I think I need to know that the thread in shader is for left eye or right eye. (I'm not using MV-hevc encoded video but just hevc encoded one)
So, what I currently do is, I assume 'amplification_id' is for the thing which determines the side of eyes. But, I'm not sure this is correct.
