Worldwind Reforged

A modern Java 17+ revival of NASA WorldWind

A 3D globe visualization toolkit for Java — GLSL shaders, GPU-accelerated surface shapes, and a full Maven build. Fully backwards compatible with the original WorldWind Java API, so it's a drop-in replacement for legacy code. Developed at Seaglass Foundry and released as open source under our Cannonforge banner.

About the Project

Worldwind Reforged is a serious real-time situational awareness platform — built as a modern revival of NASA's WorldWind, updated for Java 17+ with shader-based rendering, GPU-accelerated surface shapes, compute shaders on GL 4.3+, and a Maven-based build. Flagship showcase demos include maritime vessel tracking, live air traffic, and satellite tracking.

The API is fully backwards-compatible with the original WorldWind Java, which makes the toolkit a drop-in replacement for legacy WorldWind code. The project is fully open source — anyone can read the code, file issues, and follow along as it develops.

All releases, source, and documentation live on the Cannonforge GitHub organization.
