C Specification
// Provided by VK_KHR_ray_tracing
VkResult vkWriteAccelerationStructuresPropertiesKHR(
VkDevice device,
uint32_t accelerationStructureCount,
const VkAccelerationStructureKHR* pAccelerationStructures,
VkQueryType queryType,
size_t dataSize,
void* pData,
size_t stride);
Parameters
This command fulfills the same task as vkCmdWriteAccelerationStructuresPropertiesKHR but executed by the host.
Description
-
device
is the device which owns the acceleration structures inpAccelerationStructures
. -
accelerationStructureCount
is the count of acceleration structures for which to query the property. -
pAccelerationStructures
points to an array of existing previously built acceleration structures. -
queryType
is a VkQueryType value specifying the property to be queried. -
dataSize
is the size in bytes of the buffer pointed to bypData
. -
pData
is a pointer to a user-allocated buffer where the results will be written. -
stride
is the stride in bytes between results for individual queries withinpData
.
