Recovering Eric Graham's 1987 Amiga Juggler raytracer source code
Eric Graham's 1987 Juggler raytracer source code has been recovered and made accessible for modern use. The original code was trapped in an Amiga ADF file, which posed challenges for extraction and accessibility. A Python tool was developed to facilitate the extraction process, ensuring the preservation of the original files for future generations.
- ▪The Juggler animation was groundbreaking and initially doubted by its creators to have been made on an Amiga.
- ▪The source code was not readily available online due to being contained within an Amiga ADF file.
- ▪A Python version of the extraction tool was created to simplify the process of accessing the Juggler source code.

Opening excerpt (first ~120 words) tap to expand
By Chris HansonPosted on June 2, 2026 Recovering Eric Graham's 1987 Juggler raytracer source code AlphaPixel often gets involved with modernizing and updating old performance and graphics code. Sometimes that means client work under NDA. But sometimes it means a fun side quest in the mystical realms of curiosity, preservation, and the practical problem of getting old data into a form that can be read and used on a current machine. Today let's talk about Amiga Juggler ( https://en.wikipedia.org/wiki/Sculpt_3D ). The Juggler animation was ground-breaking and Earth-shattering. Even the Amiga's creaators (Commodore) didn't believe it had been made on an Amiga. They thought the actual computation work had been done on a mainframe, and the result simply converted to and displayed on an Amiga.
