Ray Tracing Tracking Issue

[Vecvec]

For the current implementation see https://github.com/gfx-rs/wgpu/blob/trunk/etc/specs/ray_tracing.md.
For prior details see #1040

Acceleration structures

Features

• Basic Ray Queries #6291
• Compaction Ray tracing compaction #6609
• Update instead of build if possible and preferred.
• Custom intersections (AABBs).
• as_hal for acceleration structures

Design

• Reconsider build_acceleration_structures_unsafe_tlas after as_hal has been added.

Known Bugs

• Raytracing Tests Failing on AMD GPU #6727

Support

• Vulkan
• DX12 Support DXR in wgpu-hal & naga. #6777
• Metal

Ray Queries

Features

• Basic Ray Queries #6291
• Commit candidate intersections Allow for comitting candidate intersecctions #6759
• remove undefined behavior Remove undefined behavior for ray queries #6761
• ray query get vertex return support SPV_KHR_ray_tracing_position_fetch in naga #6763

Design

• Consider renaming instance_id to instance_index. #6778

Known Bugs

• Lavapipe causes access violation accessing intersection.world_to_object #6731

Support

• Vulkan
• DX12 Support DXR in wgpu-hal & naga. #6777
• Metal (naga support, not exposed due to no acceleration structure support yet)

Ray Tracing Pipeline

• Decide on basic design
• Implement basic design Decide & implement a design for ray tracing pipelines #6760
