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;
Description
-
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_KHRandVK_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.
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.
VkPhysicalDeviceRayTracingMaintenance1FeaturesKHR can also be used in the pNext chain of
VkDeviceCreateInfo to selectively enable these features.
