vkCmdSetExtraPrimitiveOverestimationSizeEXT

Specify the conservative rasterization extra primitive overestimation size dynamically for a command buffer
primary / secondary
both
graphics
state

To dynamically set the extraPrimitiveOverestimationSize, call:

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 ::
