JMathAnim: Create Mathematical Animations in Java Like 3Blue1Brown | JavaFX In Action #27
What if you could create stunning mathematical animations, the kind you see on 3Blue1Brown, using Java and JavaFX? That's exactly what David Gutierrez built with JMathAnim, a Java(FX) library and UI that lets you animate formulas, geometric proofs, fractals, and number theory concepts, and export them straight to video.
David is a mathematician, not a trained software developer. He started JMathAnim during the COVID lockdown, inspired by the Python library Manim, and decided to build his own version in Java. In this interview he demos the tool live, explains why Ruby was chosen as the scripting language in the built-in editor, and walks us through a visualization explaining base 10 to base 5 conversion.
