i once took 12+ hours to raytrace on an 8mhz Amiga only to realize that it didn’t have any light sources and so was pitch black.
Ray tracing made possible on 42-year-old ZX Spectrum: 'reasonably fast, if you consider 17 hours per frame to be reasonably fast'

I share that memory. At least twice

It’s not that the bear dances well, it’s that the bear dances at all.

60 frames per 42.5 days, playable.
lauha@lemmy.one 4 months ago
You could get a totally playable fps if you play in geological time scale

Frames Per Stratum
slaacaa@lemmy.world 4 months ago
Nice, hitting that sweetspot at 42 fpm (frame per month)
rockSlayer@lemmy.world 4 months ago
I mean that’s pretty fucking impressive imo. I figured a RT frame would take days to render on hardware that old
VindictiveJudge@lemmy.world 4 months ago
And back when that computer was contemporary, it would have. We’ve learned a hell of a lot since Nvidia announced they had cracked real-time ray tracing all those years ago.

Now write it in Z80 assembly instead of basic and see how much faster you can get it to run.
BearOfaTime@lemm.ee 4 months ago
So true.
When I switched from basic to assembler on a Trash 80 Model 1, it was truly night and day

This computer is illegal in Florida, Texas, and Russia.

Is this true? Sounds like there’s a story you’re not telling us

It’s like playing chess by mail, but with Doom.

I misread it at first and read it as 17 frames per hour and I thought, “Yeah, that’s reasonably fast.”
fluxion@lemmy.world 4 months ago
My brain initially assumed 17 fps and I was like dayamnnnn

700 years worth of compute to do about an hour of gaming that I just did on my pc at home in realtime … damn.
Did I math it right? I was averaging about 100 fps in hogwarts for about an hour.

Say you generated 86’400’000 frames. 17h a frame that’s roughly 16’767 years.

tbf that’s probably on par with the performance Cyberpunk 2077 was doing on release

Still remember loading games from cassette tapes on this thing and the Z80.
funkless_eck@sh.itjust.works 4 months ago
“is it still loading or did it fail?”
ah, plus ça change…

Since my dedicated hybrid graphics card was broken, my gaming experience is almost the same as with this one.

What resolution? I’m guessing 64x48?
bjoern_tantau@swg-empire.de 4 months ago
The strain of going from a 32 x 22 image to a 256 x 176 one is evident in how much longer this secondary image took to render. From 879.75 seconds (nearly 15 minutes) to 61,529.88 seconds (over 17 hours). Luckily, some optimisations and time-saving tweaks meant this could be brought down to 8,089.52, or near-ish two and a half hours.
Those are really reasonable values. I guess my laptop would take that long to render a 4k image as well.
pixeltree@lemmy.blahaj.zone 4 months ago
Really depends on the complexity of the frame being rendered for how fast your laptop can render it

Back in the day we had to just use VU-3D.

I can't help to think that all that amount of effort could be better spent.

Ray tracing in MySQL instead? demozoo.org/productions/268459/
fuckwit_mcbumcrumble@lemmy.world 4 months ago
But where’s the fun in that?
glowie@h4x0r.host 4 months ago
I was thinking the same sort of thing. What’d I’d kill for the time to spend one useless shit heh.
horsey@lemm.ee 4 months ago
This is what it was like using 3D programs on an Amiga in the late 80s or early 90s. One image took hours and hours to render. 5-6 hours would be a short one, usually it was more like 12.

How many btc per decade is that?
teft@lemmy.world 4 months ago
The human eye can only see 1 frame per 18 hours so I consider this reasonably fast.
