colorPixelFormat
The Metal pixel format for the renderer’s color output.
Declaration
var colorPixelFormat: MTLPixelFormat { get }Discussion
Use this property, along with the depthPixelFormat and stencilPixelFormat properties, if you perform custom drawing with Metal (see the SCNSceneRendererDelegate and SCNNodeRendererDelegate classes) and need to create a new MTLRenderPipelineState object to change the GPU state as part of your rendering.
