Variants

AABBs

Fields

stride: DeviceSize

Stride in bytes between each entry in data.

The stride must be a multiple of 8.

Axis-aligned bounding box geometry in a bottom-level acceleration structure.

See VkAccelerationStructureGeometryAabbsDataKHR for more information.

Instances

Fields

array_of_pointers: bool

Specifies whether data is used as an array of addresses or just an array.

data: DeviceOrHostAddress

Either the address of an array of device referencing individual VkAccelerationStructureInstanceKHR structures or packed motion instance information as described in motion instances if array_of_pointers is true, or the address of an array of VkAccelerationStructureInstanceKHR structures.

Addresses and VkAccelerationStructureInstanceKHR structures are tightly packed.

Geometry consisting of instances of other acceleration structures.

See VkAccelerationStructureGeometryInstancesDataKHR for more information.

Triangles

Fields

index_data: DeviceOrHostAddress

A device or host address to memory containing index data for this geometry.

index_type: IndexType

The VkIndexType of each index element.

max_vertex: u32

The highest index of a vertex that will be addressed by a build command using this structure.

transform_data: Option<DeviceOrHostAddress>

A device or host address to memory containing an optional reference to a VkTransformMatrixKHR structure describing a transformation from the space in which the vertices in this geometry are described to the space in which the acceleration structure is defined.

vertex_data: DeviceOrHostAddress

A device or host address to memory containing vertex data for this geometry.

vertex_format: Format

The VkFormat of each vertex element.

vertex_stride: DeviceSize

The stride in bytes between each vertex.

A triangle geometry in a bottom-level acceleration structure.

See VkAccelerationStructureGeometryTrianglesDataKHR for more information.

Trait Implementations

impl Clone for AccelerationStructureGeometryData

fn clone(&self) -> AccelerationStructureGeometryData

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AccelerationStructureGeometryData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for AccelerationStructureGeometryData

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,

Feeds a slice of this type into the given Hasher.

impl PartialEq<AccelerationStructureGeometryData> for AccelerationStructureGeometryData

fn eq(&self, other: &AccelerationStructureGeometryData) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
