Show HN: An ASCII 3D Rendering Engine

This is actually pretty awesome. I enjoyed going through all the models.

I'm also not sure why I love ASCII art so much. Maybe it's because it's such an abstract way to represent something, yet our brains make perfect sense of everything.

The shading is where it all comes to life.

What is the file size of one single model on average?

apresmoi•3d ago
Thanks! The gallery holds real 3D files (.glb/.obj/.vox), ~300 KB each. The ASCII isn't stored, it's rendered live from the mesh. Its size only depends on the grid resolution, not the model: a full-screen view is ~150×50 characters, so around ~10 KB of text (a cube and a detailed mesh would produce the same byte count)

This is great! I’m going to use this for my website thanks!
apresmoi•3d ago
send it over when you have it so I can put it in the showcase :)

Love this!

I have been looking for a tool like this for so long. Very cool I will def be using for my website

> No WebGL

Why is this an advantage? I have a GPU and I'd rather it was used. As-is, one of my CPU cores is pegged at 100% just rendering the landing page.

maybe to prove the output is purely text only?
khazhoux•43m ago
When the topic is rendering 3d models using ASCII glyphs, we've already exited the realm of advantages and disadvantages. This is just supposed to be cool.
Retr0id•39m ago
Cool things are allowed to be practical and well-engineered, too. Either way, it seems weird to list a disadvantage as a headline feature.
khazhoux•33m ago
Sure. But I think the idea is already absurd, so I'm not expecting a performant engine out of it.

I get your point though, that the same ASCII rendering effect might be doable at much higher scale without pegging the CPU.

electroglyph•41m ago
heh, i came here to say basically the same thing

Wow. Where was this in the 90s when I "needed" it.

Is there a console version?

Absolutely incredible

Well done, Claude!

Is there a good reason not to use WebGL to render the scene and compute the character mapping? Even if you're dead set on outputting text to a `<pre>` you could write the ascii values out to a framebuffer and copy from that for a pretty significant speedup.

What’s up with filtering of clearly low effort AI posts here?

Every now and then I see this crap here. And people even engage into discussion. This is ridiculous.

I wouldn't call it low effort ... seems to be done over the course of months.

I agree with those 4 commits started this morning projects that get huge hype and screaming fanboys, that's absurd. But I don't think this is that.

khazhoux•43m ago
I understand this was probably vibe-coded, but it's still a lot of fun. Well done!
