Vulkan.Extensions.VK_EXT_depth_bias_control

vkCmdSetDepthBias2EXT - Set depth bias factors and clamp dynamically for a command buffer

Description

This command is functionally identical to cmdSetDepthBias, but includes extensible sub-structures that include sType and pNext parameters, allowing them to be more easily extended.

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• pDepthBiasInfo must be a valid pointer to a valid DepthBiasInfoEXT structure

• commandBuffer must be in the recording state

• The CommandPool that commandBuffer was allocated from must support QUEUE_GRAPHICS_BIT operations

• This command must only be called outside of a video coding scope

Host Synchronization

• Host access to commandBuffer must be externally synchronized

• Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

VkDepthBiasInfoEXT - Structure specifying depth bias parameters

Description

If pNext does not contain a DepthBiasRepresentationInfoEXT structure, then this command is equivalent to including a DepthBiasRepresentationInfoEXT with depthBiasExact set to FALSE and depthBiasRepresentation set to DEPTH_BIAS_REPRESENTATION_LEAST_REPRESENTABLE_VALUE_FORMAT_EXT.

Valid Usage

• If the depthBiasClamp feature is not enabled, depthBiasClamp must be 0.0

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_DEPTH_BIAS_INFO_EXT

• pNext must be NULL or a pointer to a valid instance of DepthBiasRepresentationInfoEXT

• The sType value of each structure in the pNext chain must be unique

VkDepthBiasRepresentationInfoEXT - Structure specifying depth bias parameters

Valid Usage

• If the leastRepresentableValueForceUnormRepresentation feature is not enabled, depthBiasRepresentation must not be DEPTH_BIAS_REPRESENTATION_LEAST_REPRESENTABLE_VALUE_FORCE_UNORM_EXT

• If the floatRepresentation feature is not enabled, depthBiasRepresentation must not be DEPTH_BIAS_REPRESENTATION_FLOAT_EXT

• If the depthBiasExact feature is not enabled, depthBiasExact must be FALSE

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_DEPTH_BIAS_REPRESENTATION_INFO_EXT

• depthBiasRepresentation must be a valid DepthBiasRepresentationEXT value

VkDepthBiasRepresentationEXT - Specify the depth bias representation

Description

• 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.

• 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.

• DEPTH_BIAS_REPRESENTATION_FLOAT_EXT specifies that the depth bias representation is a factor of constant r equal to 1.
