> Defines constants that specify the shading rate (for variable-rate shading, or VRS) along a horizontal or vertical axis.

Defines constants that specify the shading rate (for variable-rate shading, or VRS) along a horizontal or vertical axis. For more info, see [Variable-rate shading (VRS)](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/vrs).

## Syntax

```cpp theme={null}
typedef enum D3D12_AXIS_SHADING_RATE
{
    D3D12_AXIS_SHADING_RATE_1X = 0,
    D3D12_AXIS_SHADING_RATE_2X = 1,
    D3D12_AXIS_SHADING_RATE_4X = 2
} D3D12_AXIS_SHADING_RATE
```

## Constants
