C Specification
The VkPhysicalDeviceRayTracingMaintenance1FeaturesKHR structure is
defined as:
// Provided by VK_KHR_ray_tracing_maintenance1
typedef struct VkPhysicalDeviceRayTracingMaintenance1FeaturesKHR {
VkStructureType sType;
void* pNext;
VkBool32 rayTracingMaintenance1;
VkBool32 rayTracingPipelineTraceRaysIndirect2;
} VkPhysicalDeviceRayTracingMaintenance1FeaturesKHR;Members
This structure describes the following features:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
rayTracingMaintenance1indicates that the implementation supports the following:-
The
CullMaskKHRSPIR-V builtin using theSPV_KHR_ray_cull_maskSPIR-V extension. -
Additional acceleration structure property queries: VK_QUERY_TYPE_ACCELERATION_STRUCTURE_SERIALIZATION_BOTTOM_LEVEL_POINTERS_KHR and VK_QUERY_TYPE_ACCELERATION_STRUCTURE_SIZE_KHR.
-
A new access flag VK_ACCESS_2_SHADER_BINDING_TABLE_READ_BIT_KHR.
-
A new pipeline stage flag bit VK_PIPELINE_STAGE_2_ACCELERATION_STRUCTURE_COPY_BIT_KHR
-
-
rayTracingPipelineTraceRaysIndirect2indicates whether the implementation supports the extended indirect ray tracing command vkCmdTraceRaysIndirect2KHR.
Description
If the VkPhysicalDeviceRayTracingMaintenance1FeaturesKHR structure is included in the pNext chain of the
VkPhysicalDeviceFeatures2 structure passed to
vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each
corresponding feature is supported.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDeviceRayTracingMaintenance1FeaturesKHR, it must add an instance of the structure,
with the desired feature members set to VK_TRUE, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
