Constants
D3D11_COMPARISON_NEVER Value: 1 Never pass the comparison. |
D3D11_COMPARISON_LESS Value: 2 If the source data is less than the destination data, the comparison passes. |
D3D11_COMPARISON_EQUAL Value: 3 If the source data is equal to the destination data, the comparison passes. |
D3D11_COMPARISON_LESS_EQUAL Value: 4 If the source data is less than or equal to the destination data, the comparison passes. |
D3D11_COMPARISON_GREATER Value: 5 If the source data is greater than the destination data, the comparison passes. |
D3D11_COMPARISON_NOT_EQUAL Value: 6 If the source data is not equal to the destination data, the comparison passes. |
D3D11_COMPARISON_GREATER_EQUAL Value: 7 If the source data is greater than or equal to the destination data, the comparison passes. |
D3D11_COMPARISON_ALWAYS Value: 8 Always pass the comparison. |
Remarks
A comparison option determines whether 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 a depth-stencil buffer (see D3D11_DEPTH_STENCIL_DESC), depth-stencil operations (see D3D11_DEPTH_STENCILOP_DESC), or sampler state (see D3D11_SAMPLER_DESC).
