Amiga Did Ray-Tracing 30 Years Ago, And No One Remembers (lemmy.sdf.org)

Ray-tracing, the simulation of light rays and their interactions with the environment, is the holy grail of computer graphics and can achieve Hollywood-level imagery. The Amiga home computer, despite being capable of ray tracing in the 80s, was left out of the conversation due to hardware limitations. The Amiga played a significant role in visual effects and pioneered software that is still used in the TV and film industry today, but ultimately fell out of favor due to financial struggles and competition from home consoles.

Ray tracing is not a new thing. But what was done on the Amiga 30 years ago is quite different from what people talk about today. We're talking about real time ray tracing - that is technically challenging and requires computational resource every millisecond orders above what was available in an Amiga.

As Isaac Newton (and others before him) put it - we're standing in the shoulders of giants. In 30 years may lament that people forget what was happening in 2023 when they look at the technology of the day.

Oh wait, this isn't Reddit.

we remember it taking multiple hours to generate a single frame with a handful of objects. it was awesome.

I'd argue that every amiga user remembers. Also multitasking that worked. Wysiwyg for far less cost in publishing and if course genlock.

What can be done in real time today took hours on the Amiga back in the day.

I always like to imagine an alternate reality where the Amiga won the personal computer wars of the early 90s and it survived to this day. Now imagine the Amiga OS with technology that is available today (super fast CPUs, tons of RAM, SSDs, etc).

Can be done, you can buy a new PPC based computer and run Amiga OS 4 on it ... can't do an awful lot with it because it doesn't have a lot of programs, but you can buy one.

It should be noted that the Juggler animation was a pre-rendered loop, and wasn’t real-time raytracing.

And I bet playing battlefield at 160x120 would actually make it fun!

I remember. It took 14 hours to make one still image at 640x400.
