New blog post!
Piecewise least squares curve fitting. How to do it, and info on how to use equality constraints for values and derivatives.

It's out. They made it into Q2. https://github.com/GPUOpen-Effects/FidelityFX-FSR2
Lots of notes to check through. A reactive mask? nice!

I blogged some random notes about compiler optimizations, branches, and conditional moves.

Some generalizations of polar coordinates (kind of) so you can parametrize space around primitives beyond disks: https://www.shadertoy.com/playlist/XclfRs QT @elrono_: @iquilezles is there a way to get a tangent coordinate space from any 2D SDF in a generic way? For the circle we can get these as (angle, distance) but what about other shapes? 2022-05-22 04:32:26 UTC

Microsoft started making their own Rust bindings for Windows APIs about 6 months ago, and it's quite good! https://github.com/microsoft/windows-rs/

Siggraph 2022 papers on the web:

I particularly like GRIS (Generalized Resampled Importance Sampling: Foundations of ReSTIR).

@Icetigris Not to much a threading library, but for my home project I've based my tasking on https://github.com/RichieSams/FiberTaskingLib based on the Naughty Dog GDC presentation.
(Home project still too basic to see how well this all works out :D )

Good read! "Dissecting 'Tiny Clouds'" https://blog.demofox.org/2017/11/26/dissecting-tiny-clouds/

You know WinDirStat, utility that displays nice treemap view of folders/files on Windows? Just found altWinDirStat that does exactly the same, except like a zillion times faster. https://github.com/ariccio/altWinDirStat

New free and open source book on real time rendering:
Computer Graphics from scratch
http://www.gabrielgambetta.com/computer-graphics-from-scratch/introduction.html

"The TLDR is this book will not teach you how to use OpenGL or DirectX; instead, it can teach you how OpenGL and DirectX work."
