Description

The ray tracing pipeline API provides some ability to reorder for locality, but it is useful to have more control over how the reordering happens and what information is included in the reordering. The shader API provides a hit object to contain result information from the hit which can be used as part of the explicit sorting plus options that contain an integer for hint bits to use to add more coherency.

VkPhysicalDeviceRayTracingInvocationReorderFeaturesEXT - Structure describing feature to control ray tracing invocation reordering

Members

This structure describes the following feature:

Description

If the PhysicalDeviceRayTracingInvocationReorderFeaturesEXT 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 PhysicalDeviceRayTracingInvocationReorderFeaturesEXT, 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.

VkPhysicalDeviceRayTracingInvocationReorderPropertiesEXT - Structure describing shader module identifier properties of an implementation

Description

If rayTracingInvocationReorderReorderingHint is RAY_TRACING_INVOCATION_REORDER_MODE_REORDER_EXT there must exist conditions under which the ordered set of invocations before a reorder instruction is different than the ordered set of invocations after the reorder instruction. The ordering of a set of invocations is determined by the SubgroupId of an invocation’s subgroup and the SubGroupInvocationId of an invocation within that subgroup.

The reorder instructions are:

Because the extension changes how hits are managed there is a compatibility reason to expose the extension even when an implementation does not have sorting active.

If the PhysicalDeviceRayTracingInvocationReorderPropertiesEXT structure is included in the pNext chain of the PhysicalDeviceProperties2 structure passed to getPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.
