D3D12DDI_SHADING_RATE_0062 enumeration (d3d12umddi.h)

  • Article

The shading rate at which the variable rate shading occurs.

Syntax

typedef enum D3D12DDI_SHADING_RATE_0062 {
  D3D12DDI_SHADING_RATE_0062_1X1,
  D3D12DDI_SHADING_RATE_0062_1X2,
  D3D12DDI_SHADING_RATE_0062_2X1,
  D3D12DDI_SHADING_RATE_0062_2X2,
  D3D12DDI_SHADING_RATE_0062_2X4,
  D3D12DDI_SHADING_RATE_0062_4X2,
  D3D12DDI_SHADING_RATE_0062_4X4
} ;

Constants

 
D3D12DDI_SHADING_RATE_0062_1X1
No change to the shading rate.
D3D12DDI_SHADING_RATE_0062_1X2
Reduces vertical resolution 2x.
D3D12DDI_SHADING_RATE_0062_2X1
Reduces horizontal resolution 2x.
D3D12DDI_SHADING_RATE_0062_2X2
Reduces both axes by 2x.
D3D12DDI_SHADING_RATE_0062_2X4
Reduce horizontal res 2x, vertical by 4x.
D3D12DDI_SHADING_RATE_0062_4X2
Reduce horizontal res 4x, vertical by 2x.
D3D12DDI_SHADING_RATE_0062_4X4
Reduces both axes by 4x.

Remarks

The values are organized so that shading rates are easily decomposable into two axes, where each axis’s values are compactly represented in logarithmic space.
