C Specification

The VkDepthBiasInfoEXT structure is defined as:

// Provided by VK_EXT_depth_bias_control
typedef struct VkDepthBiasInfoEXT {
    VkStructureType    sType;
    const void*        pNext;
    float              depthBiasConstantFactor;
    float              depthBiasClamp;
    float              depthBiasSlopeFactor;
} VkDepthBiasInfoEXT;


  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • depthBiasConstantFactor is a scalar factor controlling the constant depth value added to each fragment.

  • depthBiasClamp is the maximum (or minimum) depth bias of a fragment.

  • depthBiasSlopeFactor is a scalar factor applied to a fragment’s slope in depth bias calculations.


If pNext does not contain a VkDepthBiasRepresentationInfoEXT structure, then this command is equivalent to including a VkDepthBiasRepresentationInfoEXT with depthBiasExact set to VK_FALSE and depthBiasRepresentation set to VK_DEPTH_BIAS_REPRESENTATION_LEAST_REPRESENTABLE_VALUE_FORMAT_EXT.

Valid Usage
  • VUID-VkDepthBiasInfoEXT-depthBiasClamp-08950
    If the depthBiasClamp feature is not enabled, depthBiasClamp must be 0.0

Valid Usage (Implicit)
  • VUID-VkDepthBiasInfoEXT-sType-sType

  • VUID-VkDepthBiasInfoEXT-pNext-pNext
    pNext must be NULL or a pointer to a valid instance of VkDepthBiasRepresentationInfoEXT

  • VUID-VkDepthBiasInfoEXT-sType-unique
    The sType value of each struct in the pNext chain must be unique
