C Specification

To dynamically set the extraPrimitiveOverestimationSize, call:

// Provided by VK_EXT_extended_dynamic_state3, VK_EXT_shader_object
void vkCmdSetExtraPrimitiveOverestimationSizeEXT(
    VkCommandBuffer                             commandBuffer,
    float                                       extraPrimitiveOverestimationSize);


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

  • extraPrimitiveOverestimationSize specifies the extraPrimitiveOverestimationSize.


This command sets the extraPrimitiveOverestimationSize for subsequent drawing commands when drawing using shader objects, or when the graphics pipeline is created with VK_DYNAMIC_STATE_EXTRA_PRIMITIVE_OVERESTIMATION_SIZE_EXT set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineRasterizationConservativeStateCreateInfoEXT::extraPrimitiveOverestimationSize value used to create the currently active pipeline.

Valid Usage
  • VUID-vkCmdSetExtraPrimitiveOverestimationSizeEXT-None-09423
    At least one of the following must be true:

  • VUID-vkCmdSetExtraPrimitiveOverestimationSizeEXT-extraPrimitiveOverestimationSize-07428
    extraPrimitiveOverestimationSize must be in the range of 0.0 to VkPhysicalDeviceConservativeRasterizationPropertiesEXT::maxExtraPrimitiveOverestimationSize inclusive

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

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

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

  • VUID-vkCmdSetExtraPrimitiveOverestimationSizeEXT-videocoding
    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 VkCommandPool that commandBuffer was allocated from must be externally synchronized
