Struct TlasPackage

pub struct TlasPackage { /* private fields */ }

Available on crate feature unstable-wgpu-24 only.

The safe version of TlasEntry, containing TlasInstances instead of a raw buffer.

Implementations

impl TlasPackage

pub fn new(tlas: Tlas) -> TlasPackage

Construct TlasPackage consuming the Tlas (prevents modification of the Tlas without using this package).

pub fn new_with_instances( tlas: Tlas, instances: Vec<Option<TlasInstance>>, ) -> TlasPackage

Construct TlasPackage consuming the Tlas (prevents modification of the Tlas without using this package). This constructor moves the instances into the package (the number of instances needs to fit into tlas, otherwise when building a validation error will be raised).

pub fn get(&self) -> &[Option<TlasInstance>]

Get a reference to all instances.

pub fn get_mut_slice( &mut self, range: Range<usize>, ) -> Option<&mut [Option<TlasInstance>]>

Get a mutable slice to a range of instances. Returns None if the range is out of bounds. All elements from the lowest accessed index up are marked as modified. For best performance it is recommended to prefer access to low elements and modify higher elements as little as possible. This can be done by ordering instances from the most to the least used. It is recommended to use Self::index_mut unless the option if out of bounds is required

pub fn get_mut_single( &mut self, index: usize, ) -> Option<&mut Option<TlasInstance>>

Get a single mutable reference to an instance. Returns None if the range is out of bounds. All elements from the lowest accessed index up are marked as modified. For best performance it is recommended to prefer access to low elements and modify higher elements as little as possible. This can be done by ordering instances from the most to the least used. It is recommended to use Self::index_mut unless the option if out of bounds is required

pub fn as_binding(&self) -> BindingResource<'_>

Get the binding resource for the underling acceleration structure, to be used when creating a BindGroup

pub fn tlas(&self) -> &Tlas

Get a reference to the underling Tlas.
