C Specification
The VkPhysicalDeviceAccelerationStructureFeaturesKHR structure is
defined as:
// Provided by VK_KHR_acceleration_structure
typedef struct VkPhysicalDeviceAccelerationStructureFeaturesKHR {
VkStructureType sType;
void* pNext;
VkBool32 accelerationStructure;
VkBool32 accelerationStructureCaptureReplay;
VkBool32 accelerationStructureIndirectBuild;
VkBool32 accelerationStructureHostCommands;
VkBool32 descriptorBindingAccelerationStructureUpdateAfterBind;
} VkPhysicalDeviceAccelerationStructureFeaturesKHR;
Members
This structure describes the following features:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
accelerationStructureindicates whether the implementation supports the acceleration structure functionality. See Acceleration Structures. -
accelerationStructureCaptureReplayindicates whether the implementation supports saving and reusing acceleration structure device addresses, e.g. for trace capture and replay. -
accelerationStructureIndirectBuildindicates whether the implementation supports indirect acceleration structure build commands, e.g. vkCmdBuildAccelerationStructuresIndirectKHR. -
accelerationStructureHostCommandsindicates whether the implementation supports host side acceleration structure commands, e.g. vkBuildAccelerationStructuresKHR, vkCopyAccelerationStructureKHR, vkCopyAccelerationStructureToMemoryKHR, vkCopyMemoryToAccelerationStructureKHR, vkWriteAccelerationStructuresPropertiesKHR. -
descriptorBindingAccelerationStructureUpdateAfterBindindicates whether the implementation supports updating acceleration structure descriptors after a set is bound. If this feature is not enabled,VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BITmust not be used withVK_DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_KHR.
Description
If the VkPhysicalDeviceAccelerationStructureFeaturesKHR 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 VkPhysicalDeviceAccelerationStructureFeaturesKHR, 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.
