- Add render_parabolic_orbit() with true anomaly range -π*0.95 to π*0.95
- Use 80 segments for smooth parabolic curve visualization
- Update render_orbit() branching to handle parabolic (0.98 <= e <= 1.02)
- Calculate semi-latus rectum p = h²/μ for parabolic orbits
- Maintain existing elliptical/hyperbolic orbit rendering
Claude
- Calculate orbital elements dynamically from current state and parent
- Orbits now update automatically when parent body changes
- Add support for parabolic trajectories (e ≈ 1)
- Add support for hyperbolic trajectories (e > 1) with limited extent
- Properly orient orbits in 3D space using eccentricity vector
- Limit hyperbolic/parabolic drawing to avoid infinite vertices
Refactored for code reuse and separation of concerns:
- calculate_orbital_basis(): Computes orbital reference frame
- orbital_to_cartesian(): Transforms orbital coords to 3D space
- draw_orbit_segment(): Handles rendering of individual segments
- render_elliptical_orbit(): Draws closed elliptical paths
- render_hyperbolic_orbit(): Draws open hyperbolic/parabolic paths
