Structures
VkGeometryAABBNV
Structure specifying axis-aligned bounding box geometry in a bottom-level acceleration structure
The VkGeometryAABBNV
structure specifies axis-aligned bounding box
geometry in a bottom-level acceleration structure, and is defined as:
typedef struct VkGeometryAABBNV {
VkStructureType sType;
const void* pNext;
VkBuffer aabbData;
uint32_t numAABBs;
uint32_t stride;
VkDeviceSize offset;
} VkGeometryAABBNV;
sType
is a VkStructureType value identifying this structure.pNext
isNULL
or a pointer to a structure extending this structure.aabbData
is the buffer containing axis-aligned bounding box data.numAABBs
is the number of AABBs in this geometry.stride
is the stride in bytes between AABBs inaabbData
.offset
is the offset in bytes of the first AABB inaabbData
.
The AABB data in memory is six 32-bit floats consisting of the minimum x, y, and z values followed by the maximum x, y, and z values.
Valid Usage
VUID-VkGeometryAABBNV-offset-02439
offset
must be less than the size of aabbData
VUID-VkGeometryAABBNV-offset-02440
offset
must be a multiple of 8
VUID-VkGeometryAABBNV-stride-02441
stride
must be a multiple of 8
Valid Usage (Implicit)
VUID-VkGeometryAABBNV-sType-sType
sType
must be VK_STRUCTURE_TYPE_GEOMETRY_AABB_NV
VUID-VkGeometryAABBNV-pNext-pNext
pNext
must be NULL
VUID-VkGeometryAABBNV-aabbData-parameter
If aabbData
is not VK_NULL_HANDLE, aabbData
must be a valid VkBuffer handle
