physicalSize(layer:)
Returns the dimensions, in pixels, of the area in the render target affected by the rasterization rate map.
Declaration
func physicalSize(layer layerIndex: Int) -> MTLSizeParameters
- layerIndex:
The index of the layer.
Mentioned in
Return Value
The dimensions, in pixels, of the area in the render target affected by the rasterization rate map.
Discussion
Your render targets should be at least as large as the physical size returned by this method. Each layer may have different rasterization rates and therefore different physical size requirements.
