FragCoord is now the best place online to share: -Complex graphics demos (fluid simulation, Radiance Cascades, audio visualizers, multi-pass post-processing) -Shader functions and code snippets -HLSL, MSL, live demos -Code golfing -Advanced shader debugging

Switched to Perlin noise. Normally value noise is good enough, but it left a grid-like pattern

When my own website features me

On some GPUs (eg GCN/RDNA) 24bit integer muls/mads are 4x faster than 32bit ones. 24bit instructions are not exposed in HLSL/GLSL but you can encourage the compiler to use the 24bit intrinsics by zeroing the 8 most significant bits, if the range allows it, for faster integer muls/mads.

Building on @xordev.com's tutorial on glows — here's a shader I wrote using a Lorentzian function for brightness falloff. Its closed-form antiderivative makes analytic motion blur straightforward: fragcoord.xyz/s/lmojqltl. I've made it public domain, enjoy!

Do you like oklab, but dislike numbers? Introducing: klab -- it's shorter than oklab #generative #genartclub #codegolf #glsl

I may have overscoped FragCoord's next update. It will be big

Simple things that make your shaders look cheap, and how to fix them: Starting with colors

Lazy tonemaps: rgb = tanh(rgb); rgb /= 1.0 + rgb; rgb = 1.0 - exp(-rgb);

How to looksmax your graphics. Please take the time to learn tonemapping! It's probably the most common mistake I see even in professional contexts

Viscosity f2 c = C.xy / R.y*4+R, s = flr(c), i; @(9) c+=cos(++i * c.yx + .1/(s-c) + T) / i O = exp(-3*abs(sin(c.y+f4(,.4,.2,))))

Working on a big update for FragCoord. I'm adding a Pro subscription which will give early access to features, the first being tutorial creation (integrated shader editor). Pro will help with quality control and help support development
