## Name

VkPhysicalDeviceDepthBiasControlFeaturesEXT - Structure indicating support for depth bias scaling and representation control

Loading… please wait.

## C Specification

The `VkPhysicalDeviceDepthBiasControlFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_depth_bias_control
    typedef struct VkPhysicalDeviceDepthBiasControlFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           depthBiasControl;
        VkBool32           leastRepresentableValueForceUnormRepresentation;
        VkBool32           floatRepresentation;
        VkBool32           depthBiasExact;
    } VkPhysicalDeviceDepthBiasControlFeaturesEXT;

## Members

This structure describes the following feature:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `depthBiasControl` indicates whether the implementation supports the `vkCmdSetDepthBias2EXT` command and the `VkDepthBiasRepresentationInfoEXT` structure.

- `leastRepresentableValueForceUnormRepresentation` indicates whether the implementation supports using the `VK_DEPTH_BIAS_REPRESENTATION_LEAST_REPRESENTABLE_VALUE_FORCE_UNORM_EXT` depth bias representation.

- `floatRepresentation` indicates whether the implementation supports using the `VK_DEPTH_BIAS_REPRESENTATION_FLOAT_EXT` depth bias representation.

- `depthBiasExact` indicates whether the implementation supports forcing depth bias to not be scaled to ensure a minimum resolvable difference using `VkDepthBiasRepresentationInfoEXT`::`depthBiasExact`.

## Description

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceDepthBiasControlFeaturesEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DEPTH_BIAS_CONTROL_FEATURES_EXT`
