nalgebra-spacetime

Spacetime Extension for [nalgebra]

API Documentation with KaTeX: [stable] | [master]

Present Features

• Minkowski space as special case of LorentzianMN space.
• Raising/Lowering tensor indices: dual()/r_dual()/c_dual().
• Metric contraction of degree-1/degree-2 tensors: contr()/scalar().
• Spacetime interval() with LightCone depiction.
• Inertial FrameN of reference holding boost parameters.
• Lorentz boost as new_boost() matrix.
• Direct Lorentz boost() to compose() velocities.
• Wigner rotation() and axis_angle() between to-be-composed boosts.

Future Features

• Event4/Velocity4/Momentum4/... equivalents of Point4/....
• Categorize Rotation4/PureBoost4/... as Boost4/....
• Wigner rotation() and axis_angle() of an already-composed Boost4.
• Distinguish pre/post-rotation and active/passive Boost4 compositions.
• Spacetime algebra (STA) as special case of CliffordMN space.

Pseudo-local Documentation Builds

```sh

Build and open documentation inclusive dependencies.

cargo doc --open

Update any source file, then regenerate this crate's documentation with KaTeX.

cargo tex

Refresh opened documentation.

```

With cargo tex defined in .cargo/config. Note that navigating the documentation requires web access as KaTeX is embedded via remote CDN.
