Description

This extension allows list primitives to use the primitive restart index value. This provides a more efficient implementation when layering OpenGL functionality on Vulkan by avoiding emulation which incurs data copies.

New Structures

• Extending PhysicalDeviceFeatures2, DeviceCreateInfo:

  • PhysicalDevicePrimitiveTopologyListRestartFeaturesEXT

New Enum Constants

• EXT_PRIMITIVE_TOPOLOGY_LIST_RESTART_EXTENSION_NAME

• EXT_PRIMITIVE_TOPOLOGY_LIST_RESTART_SPEC_VERSION

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_PRIMITIVE_TOPOLOGY_LIST_RESTART_FEATURES_EXT

Version History

• Revision 0, 2020-09-14 (Courtney Goeltzenleuchter)

  • Internal revisions

• Revision 1, 2021-01-11 (Shahbaz Youssefi)

  • Add the primitiveTopologyPatchListRestart feature

VkPhysicalDevicePrimitiveTopologyListRestartFeaturesEXT - Structure describing whether list type primitives can support primitive restart

Members

The members of the PhysicalDevicePrimitiveTopologyListRestartFeaturesEXT structure describe the following features:

Description

If the PhysicalDevicePrimitiveTopologyListRestartFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDevicePrimitiveTopologyListRestartFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Fields

• primitiveTopologyListRestart :: Bool

  primitiveTopologyListRestart indicates that list type primitives, PRIMITIVE_TOPOLOGY_POINT_LIST, PRIMITIVE_TOPOLOGY_LINE_LIST, PRIMITIVE_TOPOLOGY_TRIANGLE_LIST, PRIMITIVE_TOPOLOGY_LINE_LIST_WITH_ADJACENCY and PRIMITIVE_TOPOLOGY_TRIANGLE_LIST_WITH_ADJACENCY, can use the primitive restart index value in index buffers.

• primitiveTopologyPatchListRestart :: Bool

  primitiveTopologyPatchListRestart indicates that the PRIMITIVE_TOPOLOGY_PATCH_LIST topology can use the primitive restart index value in index buffers.
