C Specification

The VkAccelerationStructureCreateInfoNV structure is defined as:

// Provided by VK_NV_ray_tracing
typedef struct VkAccelerationStructureCreateInfoNV {
    VkStructureType                  sType;
    const void*                      pNext;
    VkDeviceSize                     compactedSize;
    VkAccelerationStructureInfoNV    info;
} VkAccelerationStructureCreateInfoNV;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • compactedSize is the size from the result of vkCmdWriteAccelerationStructuresPropertiesNV if this acceleration structure is going to be the target of a compacting copy.

  • info is the VkAccelerationStructureInfoNV structure specifying further parameters of the created acceleration structure.


Valid Usage
  • VUID-VkAccelerationStructureCreateInfoNV-compactedSize-02421
    If compactedSize is not 0 then both info.geometryCount and info.instanceCount must be 0

Valid Usage (Implicit)
  • VUID-VkAccelerationStructureCreateInfoNV-sType-sType

  • VUID-VkAccelerationStructureCreateInfoNV-pNext-pNext
    pNext must be NULL or a pointer to a valid instance of VkOpaqueCaptureDescriptorDataCreateInfoEXT

  • VUID-VkAccelerationStructureCreateInfoNV-sType-unique
    The sType value of each struct in the pNext chain must be unique

  • VUID-VkAccelerationStructureCreateInfoNV-info-parameter
    info must be a valid VkAccelerationStructureInfoNV structure
