Description

---

Comparison function for depth and stencil operations.

Note

Translates to D3D12_COMPARISON_FUNC for DirectX 12 implementation, and VkCompareOp for Vulkan implementation.

Values:

• WisCompareOpNone = 0: No comparison.
• WisCompareOpNever = 1: Always fail the comparison.
• WisCompareOpLess = 2: Pass the comparison if the source value is less than the destination value.
• WisCompareOpEqual = 3: Pass the comparison if the source value is equal to the destination value.
• WisCompareOpLessEqual = 4: Pass the comparison if the source value is less than or equal to the destination value.
• WisCompareOpGreater = 5: Pass the comparison if the source value is greater than the destination value.
• WisCompareOpNotEqual = 6: Pass the comparison if the source value is not equal to the destination value.
• WisCompareOpGreaterEqual = 7: Pass the comparison if the source value is greater than or equal to the destination value.
• WisCompareOpAlways = 8: Always pass the comparison.
