Constants

 
D3D12_COMPARISON_FUNC_NEVER
Value: 1
Never pass the comparison.
D3D12_COMPARISON_FUNC_LESS
Value: 2
If the source data is less than the destination data, the comparison passes.
D3D12_COMPARISON_FUNC_EQUAL
Value: 3
If the source data is equal to the destination data, the comparison passes.
D3D12_COMPARISON_FUNC_LESS_EQUAL
Value: 4
If the source data is less than or equal to the destination data, the comparison passes.
D3D12_COMPARISON_FUNC_GREATER
Value: 5
If the source data is greater than the destination data, the comparison passes.
D3D12_COMPARISON_FUNC_NOT_EQUAL
Value: 6
If the source data is not equal to the destination data, the comparison passes.
D3D12_COMPARISON_FUNC_GREATER_EQUAL
Value: 7
If the source data is greater than or equal to the destination data, the comparison passes.
D3D12_COMPARISON_FUNC_ALWAYS
Value: 8
Always pass the comparison.

Remarks

A comparison option determines how the runtime compares source (new) data against destination (existing) data before storing the new data. The comparison option is declared in a description before an object is created. The API allows you to set a comparison option for
