Worked on enhancing the Three.js 3D environments tutorial within the programminghistorian/ph-submissions repository, focusing on editorial corrections to improve interactivity and instructional clarity. Applied skills in 3D modeling, web development, and three.js to update the tutorial, aiming to boost user engagement and ensure more consistent documentation. The technical approach involved refining Markdown content and leveraging Git version control to manage changes efficiently. No major bugs were addressed during this period, as the primary goal was to elevate the quality and clarity of the tutorial. The result was a more accessible resource that supports better reader retention and learning outcomes.
