C Specification
To query acceleration structure size parameters call:
void vkCmdWriteAccelerationStructuresPropertiesNV(
VkCommandBuffer commandBuffer,
uint32_t accelerationStructureCount,
const VkAccelerationStructureNV* pAccelerationStructures,
VkQueryType queryType,
VkQueryPool queryPool,
uint32_t firstQuery);
Parameters
-
commandBuffer
is the command buffer into which the command will be recorded. -
accelerationStructureCount
is the count of acceleration structures for which to query the property. -
pAccelerationStructures
is a pointer to an array of existing previously built acceleration structures. -
queryType
is a VkQueryType value specifying the type of queries managed by the pool. -
queryPool
is the query pool that will manage the results of the query. -
firstQuery
is the first query index within the query pool that will contain theaccelerationStructureCount
number of results.
