Rotating Double Donuts #torus #donut 🍩🍩

u/TGY

I don't think you need "var" there. It works fine without it :)
u/New_Core

nice, and its 5 FPS faster with the "var" then without on my old machine.

Nice! Double donuts everywhere!
u/pavel

Not a fan of the obfuscated code. Looks nice to people who don't care to understand it but hurts your fellow coders that want to play around with it, which is a big part of Dwitter for me.

u/rodrigo.siqueira

I posted a cleaner version (remix). I usually avoid obfuscated code, but in this case it was for aesthetic reasons and for fun ("donuts everywhere" style). The 💡&&⭕⭕➜🍩🍩 part was just to illustrate, it has no functionality in the code.
u/tomxor

I think Pavel might be refering to unicode tofu, I get this too... the "⭕⭕➜🍩🍩" bit renders but almost all the other non-ASCII chars are tofu. I think it depends on what browser/OS combo you have.
u/tomxor

... and which fonts you've bothered installing.

I made a hi res version here: http://glslsandbox.com/e#68682.1
u/rodrigo.siqueira

The hi res version is a hundred or thousand times faster. I didn't know about glslsandbox. Nice gallery of fast GLSL demos (OpenGL Shading Language).
u/danny@hille.dk

I just recently got aware of http://glslsandbox.com/ - and by reading some of the code from the demos i also found https://www.shadertoy.com/ - but be aware you really need a computer with a powerfull graphics card or else everything just freezes up :-)
u/danny@hille.dk

I also found that, the shaderlanguage is more like c than javascript, and the way you code shaders, are quite different from codeing for canvas2d :-) - Challenge accepted!
u/danny@hille.dk

Here is a version where I have fixed some minor bugs http://glslsandbox.com/e#68682.7
u/danny@hille.dk

Please share, if any of you guys creates something on glslsandbox
u/rodrigo.siqueira

I created a remix of a simple code I found on glslandbox: http://glslsandbox.com/e#68725.0 (Animated blue 3D waves)
u/joeytwiddle

If you like glsandbox, you might also like https://shadertoy.com/
u/danny@hille.dk

u/rodrigo.siqueira that looks awesome!
u/danny@hille.dk

Thanks u/joeytwiddle, i did try shadertoy, but the website is a bit to harsh on my laptop :-)
u/rodrigo.siqueira

I also created 2 other remixes: Rotating Ring of Fire http://glslsandbox.com/e#68726.0 and Purple Unfolding Waves Under a Deep Blue Sky http://glslsandbox.com/e#68725.1
u/danny@hille.dk

u/rodrigo.siqueira cool stuff, I also have been palying with GLSL i have converted some of my dweets FX: http://glslsandbox.com/e#68778.0
u/danny@hille.dk

I really like the organic look-feel, you can achieve with sin/cos event with just black/white http://glslsandbox.com/e#68767.0 I'm properbly gonna make this into a dweet :-)
