Planck.js
planck.js ist eine 2D-Rigid-Body-Physik-Engine für JavaScript und HTML5, basierend auf Box2D. Sie bietet ein Framework zur Simulation physikalischer Interaktionen und zur Berechnung der Bewegung fester Körper innerhalb einer zweidimensionalen virtuellen Umgebung.
Die Engine ist für plattformübergreifendes Web-Gaming konzipiert und ermöglicht die Implementierung von Rigid-Body-Dynamik über verschiedene Webbrowser und Geräte hinweg.
Die Bibliothek verwaltet die Simulation durch einen Constraint-basierten Physik-Solver und Rigid-Body-State-Management. Sie nutzt iterative Impulsauflösung, semi-implizite Euler-Integration und dynamische AABB-Baum-Partitionierung für Kollisionserkennung und Objektbewegung.
