Nah-c-Flug

WebGL-Flug bei relativistischer Geschwindigkeit: Längenkontraktion, Zeitdilatation, Doppler-Verschiebung und Scheinwerfereffekt entlang eines Korridors.

About this tool

Fly a camera down a corridor at speed β = v/c. The scene shows classic special-relativistic effects (stylized, not a full light-field renderer):

  • Length contraction — rest-frame spacing of poles shrinks by 1/γ along the boost.
  • Time dilation — traveler proper time advances as dτ = dt/γ.
  • Doppler / headlight — approaching light is blueshifted; FOV widens with γ.
  • Terrell / Penrose — light-travel time makes side faces of poles visible (rotation-like skew).
  • Aberration — star directions compress toward the forward direction via cos θ = (cos θ′ + β)/(1 + β cos θ′).

Controls: set β, toggle each effect, then Run. Pause or reset anytime. Zoom with Ctrl+scroll.

Limitations: geometric units; no full light-travel integration per pixel; no general relativity.
