Configuration of a stencil test.

Fields

compare: Compare

The comparison to perform between the existing stencil value in the stencil buffer, and the reference value (given by reference).

pass_op: StencilOp

The operation to perform when both the depth test and the stencil test passed.

fail_op: StencilOp

The operation to perform when the stencil test failed.

depth_fail_op: StencilOp

The operation to perform when the stencil test passed but the depth test failed.

compare_mask: Option<u32>

Selects the bits of the unsigned integer stencil values participating in the stencil test.

Ignored if compare is Never or Always.

If None, then this value is dynamic and will need to be set when drawing. Doesn't apply if compare is Never or Always.

Note that if this value is Some in stencil_front, it must also be Some in stencil_back (but the content can be different). If this value is None in stencil_front, then it must also be None in stencil_back. This rule doesn't apply if compare is Never or Always.

write_mask: Option<u32>

Selects the bits of the unsigned integer stencil values updated by the stencil test in the stencil framebuffer attachment.

If None, then this value is dynamic and will need to be set when drawing.

Note that if this value is Some in stencil_front, it must also be Some in stencil_back (but the content can be different). If this value is None in stencil_front, then it must also be None in stencil_back.

reference: Option<u32>

Reference value that is used in the unsigned stencil comparison.

If None, then this value is dynamic and will need to be set when drawing.

Note that if this value is Some in stencil_front, it must also be Some in stencil_back (but the content can be different). If this value is None in stencil_front, then it must also be None in stencil_back.
