`wgpu` supports an experimental version of ray tracing which is subject to change. The extensions allow for acceleration structures to be created and built (with
`Features::EXPERIMENTAL_RAY_TRACING_ACCELERATION_STRUCTURE` enabled) and interacted with in shaders. Currently `naga` only supports ray queries

The documentation and specific details of the functions and structures provided
can be found with their definitions.
Acceleration structures do not have a separate feature, instead they are enabled by `Features::EXPERIMENTAL_RAY_QUERY`, unlike vulkan.
When ray tracing pipelines are added, that feature will also enable acceleration structures.
A [`Blas`] can be created with [`Device::create_blas`].
A [`Tlas`] can be created with [`Device::create_tlas`].
