Just getting started with VisionPro with goal to learn capabilities and get familiar. I'm building a simple app to take visual input from camera and apply filters prior to display on VisionPro headset - think things like increase saturation of one color, show red/green colorblind vision, etc. Struggling to understand what frameworks I need to dig into - is Metal required to access this type of functionality or is there a simpler way to go about it? TYIA!!
