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
The members of the VkPhysicalDeviceAccelerationStructureFeaturesKHR
structure describe the following features:
Description
-
accelerationStructure
indicates whether the implementation supports the acceleration structure functionality. See Acceleration Structures. -
accelerationStructureCaptureReplay
indicates whether the implementation supports saving and reusing acceleration structure device addresses, e.g. for trace capture and replay. -
accelerationStructureIndirectBuild
indicates whether the implementation supports indirect acceleration structure build commands, e.g. vkCmdBuildAccelerationStructuresIndirectKHR. -
accelerationStructureHostCommands
indicates whether the implementation supports host side acceleration structure commands, e.g. vkBuildAccelerationStructuresKHR, vkCopyAccelerationStructureKHR, vkCopyAccelerationStructureToMemoryKHR, vkCopyMemoryToAccelerationStructureKHR, vkWriteAccelerationStructuresPropertiesKHR. -
descriptorBindingAccelerationStructureUpdateAfterBind
indicates 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_BIT
must not be used withVK_DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_KHR
.
If the VkPhysicalDeviceAccelerationStructureFeaturesKHR
structure is
included in the pNext
chain of VkPhysicalDeviceFeatures2, it is
filled with values indicating whether the feature is supported.
VkPhysicalDeviceAccelerationStructureFeaturesKHR
can also be used in
the pNext
chain of VkDeviceCreateInfo to enable the features.
