scenix v0.8.0

Install

[dependencies]
scenix = { version = "0.8.0", features = ["loader", "renderer", "post"] }

Highlights

• New default scenix-raycaster crate for CPU-side scene picking with node-level SAH BVH traversal and exact mesh triangle intersections.
• New default scenix-helpers crate for validated LineGeometry debug helpers: grids, axes, bounds, arrows, lights, cameras, and skeletons.
• Raycaster::from_camera_ndc bridges camera screen rays into picking workflows without requiring renderer or GPU readback.
• GeometryProvider lets applications keep mesh storage in their own maps or slices while still using BVH acceleration.
• Loaders, renderer, and post-processing remain optional; WASM wrappers and animato integration remain deferred to later milestones.

Raycasting + helpers example

let mut raycaster = Raycaster::new();
