D3DDDI_MULTISAMPLINGMETHOD structure (d3dukmdt.h)

  • Article

The D3DDDI_MULTISAMPLINGMETHOD structure describes a multiple-sampling method.

Syntax

typedef struct _D3DDDI_MULTISAMPLINGMETHOD {
  [out] UINT NumSamples;
  [out] UINT NumQualityLevels;
} D3DDDI_MULTISAMPLINGMETHOD;

Members

[out] NumSamples

The number of subpixels that are used in the multiple-sampling method (for example, 2 for 2x and 8 for 8x multiple-sampling).

[out] NumQualityLevels

The upper bound on the quality range that is supported for the multiple-sampling method. The range includes values from 0 through the reported maximum quality setting.

Remarks

The driver can partition its quality levels for a given multiple-sampling method into as many increments as it requires; however, each incremental step noticeably improves quality of the presented image.

Requirements

Requirement Value
Minimum supported client Available in Windows Vista and later versions of the Windows operating systems.
