Historic 1987 Amiga Juggler Raytracer Source Code Recovered, Extracted, and Published on GitHub

AlphaPixel documented the recovery and preservation of the source code behind Eric Graham’s influential 1987 Amiga Juggler raytracer, a landmark project in early computer graphics. The Juggler animation became famous for demonstrating advanced 3D rendering capabilities on the Commodore Amiga, to the extent that some observers initially doubted it had been created on the machine itself. The source code had long been difficult to access because it was stored inside an Amiga ADF disk image, and some historical references to the files had disappeared over time. To preserve the material, AlphaPixel located a surviving copy of the disk image on Archive.org and extracted its contents using a new Python implementation of the extract-adf utility. The Python tool, generated with assistance from OpenAI Codex and published separately on GitHub, supports extraction of OFS-family Amiga disk images and was validated against multiple test datasets. The recovered archive contains original C source files, a BASIC version of the raytracer, scene description files, Amiga executables, and animation-related data. Analysis of the code revealed that while the raytracer source was present, the separate Scene Simulation Generator (SSG) tool used to create some famous Juggler-related scenes was not included. Before publishing the recovered materials, AlphaPixel contacted Eric Graham to clarify redistribution rights. Graham responded that anyone could use the code provided he received attribution, allowing the repository to be published openly. The final GitHub archive now serves as a preservation resource, making historically significant computer graphics software easier to study and access without requiring Amiga-specific tools or emulation.
