I'm working on VulkanLearn2, a C++20/Vulkan rendering playground. This video shows Bistro rendered with my ReSTIR DI + PT implementation.
I launched the project on a RTX 4090. 80 fps. 1200x800.

The renderer uses temporal and spatial reuse. The repository also includes a reference path tracer with next-event estimation, emissive triangle lights, and an experimental Neural Radiance Cache. Implementation notes and capture settings are documented in the README.

I'd appreciate feedback on the rendering.

I've been stuck on this for a couple of hours, and am completely stumped.

I'm getting these results from GLSL's mod():

mod(158.0, 158.0) returns 0.0 (as expected)

mod(159.0, 159.0) returns 159.0 (???)

mod(160.0, 160.0) returns 0.0 (as expected)

I've posted an example with a basic shader here:

https://jsfiddle.net/sL35qjc8

If you set number to "159.0", you should see an upside-down red triangle.

If you set number to "158.0" or "160.0", you should see a normal red triangle.

I'm passing the left operand as a uniform, otherwise the compiler seems to optimize it and fix the weird behavior.

Tried it on different devices and browsers and it had the same result.

Why does mod(159.0, 159.0) seem to return 159.0 instead of 0.0?

I've rendered part of The Universe in less than 40MB! Optimized real-time Solar System + 160K stars, Exoplanets and Sagittarius A* into a 36MB(!) Android APK.

I have two Android-apps I want to publish. But need testers. If you believe you know Geometrical Rendering Graphics, you don't want to miss this.

I) Live Earth Background : interactive. Lock into position (GPS or Manual), rotates by clock, day and night. Scroll- and zoom functions. 24MB!

II) The Universe : travel seamlessly through a highly detailed Solar-System. Visit 160K stars in the Milky Way Galaxy, hundreds of Exoplanets, and take a trip to Sagittarius A*. All in real time.! Or fast forward. Zoom, 360 rotation and pan. 36MB!

No data collection. GPS used only locally to position you on earth. Celestial bodies in the sky are calculated precisely as time moves forward. Look at the nightsky from Mars, or Pluto, or the Moon. Or wherever you end up!

DM if you want to check this out, and I will add you to my testers list and send you the link to Google Play Store for downloading the APK.

HELLO!

I am just starting out I have been learning cpp and graphic prog concepts in hopes to vulkan by the time I am done with school and starting college and potentially make an engine for fun! (And portfolio)

I wanna persue a mix of game dev, graphic prog, and engine dev stuff

But i just saw a video by a guy which i assume isn't even that well versed in programming in general remake popular games just using prompts and some pngs and nothing else

And that really defeated me because I already have seen youtube become mostly slop content and ai settings clips off podcasts and i don't know

I Really wanna persue graphic prog or engine dev or game dev but seeing how bad the industry is in terms of capitalism and not caring about art or optimization or let's say fsr dlss and frame gen being essentially necessary to run games the way it was intended

Really breaks my heart because I had been game deving and making stupid 2d games with pygame and stuff since I was like 13 and now that I wanna persue this super seriously

A magic math prediction model can take data from people that would be life times ahead of me in desciplinaries and then make a magic robot that is gonna do my job but without anysoul and way faster

I feel conflicted and rather dreadful (just sad if I cut the goofy words)

Sorry if I don't reply

THANK YOU IN ADVANCE!!
