nalgebra-spacetime

Spacetime Extension for [nalgebra]

Present Features

• Minkowski space as n-dimensional 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 and so on.
• Categorize Rotation4 and PureBoost4 as Boost4 and so on.
• Wigner rotation() and axis_angle() of an already-composed Boost4.
