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
-
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.
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.
