In August 2025, Alexander Haeberle contributed targeted performance and quality improvements to the mrdoob/three.js repository, focusing on 3D graphics and WebGL optimization using JavaScript and shading languages. He developed a feature that optimizes array texture updates by uploading only changed data, reducing frame times and CPU/GPU workload in complex scenes. Alexander also addressed two critical bugs: one ensuring DragControls events fire reliably and update cursor feedback, and another correcting instanced rendering buffer sizing by accurately deriving instance counts. His work enhanced rendering stability and user experience, demonstrating a deep understanding of graphics programming and front-end development challenges.
