C Specification

To dynamically set the depth bias parameters, call:

// Provided by VK_VERSION_1_0
void vkCmdSetDepthBias(
    VkCommandBuffer                             commandBuffer,
    float                                       depthBiasConstantFactor,
    float                                       depthBiasClamp,
    float                                       depthBiasSlopeFactor);

Parameters

  • commandBuffer is the command buffer into which the command will be recorded.

  • 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.

Description

This command sets the depth bias parameters for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_DEPTH_BIAS set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the corresponding VkPipelineInputAssemblyStateCreateInfo::depthBiasConstantFactor, depthBiasClamp, and depthBiasSlopeFactor values used to create the currently active pipeline.

Valid Usage
  • VUID-vkCmdSetDepthBias-depthBiasClamp-00790
    If the depth bias clamping feature is not enabled, depthBiasClamp must be 0.0

Valid Usage (Implicit)
  • VUID-vkCmdSetDepthBias-commandBuffer-parameter
    commandBuffer must be a valid VkCommandBuffer handle

  • VUID-vkCmdSetDepthBias-commandBuffer-recording
    commandBuffer must be in the recording state

  • VUID-vkCmdSetDepthBias-commandBuffer-cmdpool
    The VkCommandPool that commandBuffer was allocated from must support graphics operations

Host Synchronization
  • Host access to commandBuffer must be externally synchronized

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