YAYGND

YAYGND (Yet Another Yggdrasil Graphical Node Designer) is an open‑source visual programming framework designed for creating interactive 3D applications and simulation environments. It was first released in 2019 by a team of university researchers at the University of Oslo, who sought to provide a modular tool that could integrate easily with existing game engines such as Unity and Unreal. The project is maintained under the MIT license on GitHub, where contributors from around the world can submit pull requests, report issues, and suggest new features.

The core of YAYGND is a node‑based editor that allows users to construct logic flows, animation sequences, and physics interactions without writing traditional code. Nodes represent operations such as mathematical transformations, input handling, and procedural generation, and can be connected by edges that carry data streams. The editor also supports real‑time preview and debugging, making it suited for rapid prototyping of VR/AR experiences.

YAYGND has been adopted by several academic labs for coursework in computer graphics and by indie developers for prototype prototypes. A series of video tutorials and example projects are distributed alongside the source code to lower the barrier to entry.

The community actively discusses improvements on both the project’s Reddit channel and the Discord server, and the documentation regularly incorporates feedback from users. The framework continues to evolve, with recent releases adding support for shader programming and machine‑learning integration.
