What is the equivalent in metal of glClearStencil(AStencil)

What is the equivalent in metal of glClearStencil(AStencil)? glClearStencil specifies the index used by glClear to clear the stencil buffer. s is masked with 2 m - 1 , where m is the number of bits in the stencil buffer.

Solution

  • The stencil value to use when the stencil render target is cleared. If the loadAction property of the render target is set to MTLLoadActionClear, then at the start of a render pass, the contents of the texture are filled with the value stored in the clearStencil property. Otherwise, clearStencil is ignored.

    The default value is 0.
