vkCmdSetExtraPrimitiveOverestimationSizeEXT(3)

C Specification

To dynamically set the extraPrimitiveOverestimationSize, call:

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

Parameters

commandBuffer is the command buffer into which the command will be recorded.
extraPrimitiveOverestimationSize specifies the extraPrimitiveOverestimationSize.

Description

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:
- The extendedDynamicState3ExtraPrimitiveOverestimationSize feature is enabled
- The shaderObject feature is enabled
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
