vkCmdSetPrimitiveRestartIndexEXT - Set primitive assembly restart index dynamically for a command buffer

Description

This command sets a custom primitive restart index for subsequent drawing commands. Binding an index buffer invalidates the custom index value.

Valid Usage

• The primitiveRestartIndex feature must be enabled

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• commandBuffer must be in the recording state

• The CommandPool that commandBuffer was allocated from must support QUEUE_GRAPHICS_BIT operations

• 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 CommandPool that commandBuffer was allocated from must be externally synchronized

VkPhysicalDevicePrimitiveRestartIndexFeaturesEXT - Structure describing features to configure primitive restart index

Description

If the PhysicalDevicePrimitiveRestartIndexFeaturesEXT 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. If the application wishes to use a Device with any features described by PhysicalDevicePrimitiveRestartIndexFeaturesEXT, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
