## Name

VkDepthBiasRepresentationEXT - Specify the depth bias representation

Loading… please wait.

## C Specification

Possible values of VkDepthBiasRepresentationInfoEXT::`depthBiasRepresentation`, specifying the depth bias representation are:

    // Provided by VK_EXT_depth_bias_control
    typedef enum VkDepthBiasRepresentationEXT {
        VK_DEPTH_BIAS_REPRESENTATION_LEAST_REPRESENTABLE_VALUE_FORMAT_EXT = 0,
        VK_DEPTH_BIAS_REPRESENTATION_LEAST_REPRESENTABLE_VALUE_FORCE_UNORM_EXT = 1,
        VK_DEPTH_BIAS_REPRESENTATION_FLOAT_EXT = 2,
    } VkDepthBiasRepresentationEXT;

## Description

- `VK_DEPTH_BIAS_REPRESENTATION_LEAST_REPRESENTABLE_VALUE_FORMAT_EXT` specifies that the depth bias representation is a factor of the format’s r as described in https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#primsrast-depthbias-computation.

- `VK_DEPTH_BIAS_REPRESENTATION_LEAST_REPRESENTABLE_VALUE_FORCE_UNORM_EXT` specifies that the depth bias representation is a factor of a constant r defined by the bit-size or mantissa of the format as described in https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#primsrast-depthbias-computation.

- `VK_DEPTH_BIAS_REPRESENTATION_FLOAT_EXT` specifies that the depth bias representation is a factor of constant r equal to 1.
