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.

  • VkPhysicalDevicePrimitiveTopologyListRestartFeaturesEXT

• VK_EXT_PRIMITIVE_TOPOLOGY_LIST_RESTART_EXTENSION_NAME
• VK_EXT_PRIMITIVE_TOPOLOGY_LIST_RESTART_SPEC_VERSION
