## Name

VkDepthBiasRepresentationInfoEXT - Structure specifying depth bias parameters

Loading… please wait.

## C Specification

The `VkDepthBiasRepresentationInfoEXT` structure is defined as:

    // Provided by VK_EXT_depth_bias_control
    typedef struct VkDepthBiasRepresentationInfoEXT {
        VkStructureType                 sType;
        const void*                     pNext;
        VkDepthBiasRepresentationEXT    depthBiasRepresentation;
        VkBool32                        depthBiasExact;
    } VkDepthBiasRepresentationInfoEXT;

## Members

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

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

- `depthBiasRepresentation` is a VkDepthBiasRepresentationEXT value specifying the depth bias representation.

- `depthBiasExact` specifies that the implementation is not allowed to scale the depth bias value to ensure a minimum resolvable distance.

## Description

Valid Usage

- VUID-VkDepthBiasRepresentationInfoEXT-leastRepresentableValueForceUnormRepresentation-08947
  If the `leastRepresentableValueForceUnormRepresentation` feature is not enabled, `depthBiasRepresentation` must not be `VK_DEPTH_BIAS_REPRESENTATION_LEAST_REPRESENTABLE_VALUE_FORCE_UNORM_EXT`

- VUID-VkDepthBiasRepresentationInfoEXT-floatRepresentation-08948
  If the `floatRepresentation` feature is not enabled, `depthBiasRepresentation` must not be `VK_DEPTH_BIAS_REPRESENTATION_FLOAT_EXT`

- VUID-VkDepthBiasRepresentationInfoEXT-depthBiasExact-08949
  If the `depthBiasExact` feature is not enabled, `depthBiasExact` must be `VK_FALSE`

Valid Usage (Implicit)

- VUID-VkDepthBiasRepresentationInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_DEPTH_BIAS_REPRESENTATION_INFO_EXT`

- VUID-VkDepthBiasRepresentationInfoEXT-depthBiasRepresentation-parameter
  `depthBiasRepresentation` must be a valid VkDepthBiasRepresentationEXT value
