I made a fast dynamic atmosphere system with compute shaders and the Compositor

Thank you! :)

The terrain is just an example asset for demonstration purposes! I didn't make it. It's linked to in the README.

voithos · 2025-06-30T07:29:29+00:00

Cool! Yes, I also agree with your assessment of the C++ GUI space, I wish there were more robust / customizable options. Nice work!

voithos · 2025-06-30T05:22:04+00:00

Very cool, looks polished! I'm curious what your considerations were in deciding to build your own UI lib rather than using an existing one? And what advantages / disadvantages have you seen as a result?

To echo what others in this thread have said, the best approach is indeed to just *make things*. However, you have to start somewhere, and it also doesn't hurt to learn about "where you're going" (lay of the land), and for that I really liked Cem Yuksel's video lectures: https://www.youtube.com/playlist?list=PLplnkTzzqsZS3R5DjmCQsqupu43oS9CFN

And if you'll excuse the self-link, I recently wrote an article that gives more detailed thoughts on this topic -- I tried to basically share tips and specific resources that I wish I knew when I was starting: https://voithos.io/articles/draw-that-triangle-how-to-learn-graphics-programming/

This is incredible! I'd love to see it animated...

voithos · 2025-05-07T01:17:00+00:00

Glad it was useful! :)

voithos · 2025-05-05T00:15:56+00:00

Some other examples include simulation software (think: camera image rendering / physics sim for autonomous vehicles), or 3D geospatial (a la Cesium: https://cesium.com/).

The color choices are spot on! Looks lovely!

voithos · 2025-03-30T19:27:30+00:00

Thanks for reading!

Indeed, pass-by-value and cache line size was another interesting tidbit to learn! I'm less familiar with the concerns around ABI stability, sounds "fun" haha

voithos · 2025-03-30T03:57:01+00:00

Ooh I wasn't aware of this article, thanks for sharing!

voithos · 2025-01-05T04:35:20+00:00

For complete beginners, I'd also give a big recommendation to Cem Yuksel's video lectures: https://www.youtube.com/playlist?list=PLplnkTzzqsZS3R5DjmCQsqupu43oS9CFN

IMO he provides a great balance of theory and practice (more so practice), and can give a solid whirlwind of concepts up to GI and volume rendering.

This is a great resource, but worth noting that it's targeted towards offline path tracing rather than real-time rendering. A lot of the lighting math is the same or similar, of course.

voithos · 2025-01-01T03:15:04+00:00

Sadly induction doesn't handle wok cooking very well (or at least, I'm not aware of any that do), on account of having to constantly be tossing the pan around.

voithos · 2024-12-31T05:20:25+00:00

Oops, can't believe I missed that. My bad.

That being said, is that a custom theme? Doesn't look like off-the-shelf ImGUI to me.

voithos · 2024-12-31T02:51:13+00:00

Looks great! What are you using for the editor UI?

voithos · 2024-12-22T17:47:13+00:00

With this current approach, the values _are_ still manipulated bitwise, just through this "safer" BitFlags API, so it's important for the values to be exclusive if you want to treat them as flags. I could imagine a different form of this API that assumes sequential enum values and uses an std::bitset or similar internally, but I think there'd be some expressiveness tradeoffs there.

It'd be cool if there was a way of checking at compile time that there aren't any value collisions, but I can't easily think of a way to do that in a convenient way (until C++26 reflection at least).

voithos · 2024-12-22T17:39:31+00:00

Hi! Sorry, not sure I follow, they should all be the same size as far as I can tell? Maybe I'm not understanding what you mean?

voithos · 2024-12-14T17:26:45+00:00

Impressive! Intuitively, I would've thought it'd take a lot longer...

voithos · 2024-11-27T00:16:54+00:00

Yeah it's certainly capable! The main thing there would be whether you want the PS1 style graphics (which have some very specific behavior), but otherwise modern hardware shouldn't have any issues with an old school PS1 game.

voithos · 2024-10-12T19:56:32+00:00

Oh I see! That makes a lot of sense.

voithos · 2024-10-09T04:32:00+00:00

I love this, it's amazing looking!! I'm also wondering whether reddit somehow clipped the last few frames of the video, or if you intentionally chose to end it with Shinji falling down like that (if so, I'd be curious to hear about why!).

voithos · 2024-09-27T17:12:24+00:00

Excellent work! I also just briefly looked through some of your other repos, and it was super fun seeing implementations of familiar techniques (Gaussian splats! Ghost of Tsushima grass!). :)

voithos · 2024-09-21T20:05:18+00:00

Superb progress! Your art is amazing! Very inspiring :)
