DXGI_SAMPLE_DESC structure (dxgicommon.h)

Describes multi-sampling parameters for a resource.

Syntax

typedef struct DXGI_SAMPLE_DESC {
  UINT Count;
  UINT Quality;
} DXGI_SAMPLE_DESC;

Members

Count

Type: UINT

The number of multisamples per pixel.

Quality

Type: UINT

The image quality level. The higher the quality, the lower the performance. The valid range is between zero and one less than the level returned by ID3D10Device::CheckMultisampleQualityLevels for Direct3D 10 or ID3D11Device::CheckMultisampleQualityLevels for Direct3D 11.

For Direct3D 10.1 and Direct3D 11, you can use two special quality level values. For more information about these quality level values, see Remarks.

Remarks

This structure is a member of the DXGI_SWAP_CHAIN_DESC1 structure.

The default sampler mode, with no anti-aliasing, has a count of 1 and a quality level of 0.

If multi-sample antialiasing is being used, all bound render targets and depth buffers must have the same sample counts and quality levels.

Differences between Direct3D 10.0 and Direct3D 10.1 and between Direct3D 10.0 and Direct3D 11: Direct3D 10.1 has defined two standard quality levels: D3D10_STANDARD_MULTISAMPLE_PATTERN and D3D10_CENTER_MULTISAMPLE_PATTERN in the D3D10_STANDARD_MULTISAMPLE_QUALITY_LEVELS enumeration in D3D10_1.h. Direct3D 11 has defined two standard quality levels: D3D11_STANDARD_MULTISAMPLE_PATTERN and D3D11_CENTER_MULTISAMPLE_PATTERN in the D3D11_STANDARD_MULTISAMPLE_QUALITY_LEVELS enumeration in D3D11.h.
