setStencilReferenceValue(_:)
Configures the same comparison value for front- and back-facing primitives.
Declaration
func setStencilReferenceValue(_ referenceValue: UInt32)Parameters
- referenceValue:
A stencil test comparison value the render pipeline applies to both front- and back-facing primitives.
Discussion
The command sets the same reference value for front- and back-facing primitives (see stencilCompareFunction, frontFaceStencil, and backFaceStencil). This reference value applies to the stencil state you set with the setDepthStencilState(_:) method.
The render pass’s default reference value for the front and back stencil compare function is 0.
