React Native | WebGPU | Math | Shaders. Creator of ~ Creative & artistic photo filters and animated effects

[Neil Sainsbury @superligious]

My app https://t.co/wvtlba4ehR is now available. Made w/ React Native, @expo, @ReactNativeSkia and more, it lets you turn your photos into creative, animated, mathematically inspired art. 100% local. No AI. Full creative control!

Would love you to try it! https://t.co/TCxCFmux3p

A strange thing. The first two weeks I had a broken hand (but didn't know it and worked through it) were less physically painful than the last two weeks have been, knowing I have a broken hand and resting it completely.

@alonzuman Super cool!

I feel like every programmer is falling into the same trap: thinking that if you just ask Claude some questions and read the answers you can deeply understand a system. Your brain doesn’t work that way, you need to be forced to think, prove your knowledge, and recall over time.

In addition to sprained wrists, turns out I’ve been working for the last 3 weeks with a fractured thumb 😔 Gotta properly stay off the keyboard coming up I think.

Turned Anton Palmqvist's excellent https://t.co/iZjEipi6hY into a three.js viewer here at https://t.co/Geh2jjwDwL so you can get a feel of the materials. Easily copy albedo values and test your own models with the material library

@saulsharma @expo Super cool!

Something I wrote about here: https://t.co/5vtReAoYLc

We're about to see some of the least intellectually capable people ever enter university and the workforce due to a complete trained dependence on AI for all thought.

[Neetu Arnold @neetu_arnold]

University of California STEM professors want standardized tests back due to severe math deficiencies among students:

“We now observe preparation gaps so severe that instructors must reteach middle school mathematics”

“The current admissions metric, based primarily on GPA & essays, can no longer reliably distinguish readiness for university-level STEM majors in an era of severe grade inflation & AI assisted application essays”

[Antonio Lupetti @antoniolupetti]

"Advanced Calculus" is a free book of more than 500 pages published by the Harvard Mathematics Department and represents a real gold mine for the study of mathematical analysis.

It covers normed vector spaces, compactness and completeness, multivariable differential calculus, integration, differential equations, multilinear forms, differentiable manifolds, exterior calculus, potential theory, and classical mechanics.

It is a mathematically substantial book, rigorous yet accessible to readers with a solid background in analysis and linear algebra. Despite its advanced level, it maintains remarkable clarity and develops the theory in a progressive and coherent way.

It is one of those resources worth keeping in your mathematical toolbox, useful not only for mathematicians but also for those working in physics, mechanics, engineering, data science, and computer science, where many of the concepts developed in the text find direct applications.

New shader-based photo filter I've been working on yesterday & today. Lots of parameters going in (bloom, light streaks, halftone dots, color noise, chromatic ab, light streaks, etc.) so you can get quite unique results out of it depending on your choices.

[Neil Sainsbury @superligious]

Btw, that blue button you see enabled on the right is my new "Artistic Auto-Crop" setting which automatically crops images to try to create an interesting artistic result. Pretty cool if I do say so myself :-)

[Neil Sainsbury @superligious]

Working on a new effect today for https://t.co/wvtlba4ehR ~ inspired by some recent sketching. I thought...wouldn't it be interesting to generate a polygon tessellation and then hatch each polygon. You can toggle to render the polygon edges or not for a unique effect.

[Neil Sainsbury @superligious]

@wavefnx For some reason this made me think of your art style @sinusoidalsnail 😂

[Yining Karl Li @yiningkarlli]

I'm a little late to the party on this one since it's from January, but I just read this great blog post by Jure Triglav walking through implementing surfel-based global illumination. It's got a bunch of really cool interactive toys/visualizers!

Working on a new set of screenshots today for https://t.co/wvtlba4ehR using this guide shared by @PaulSolt ... not sure if I nailed it, but I think much improved vs my current store listing :-)

[Neil Sainsbury @superligious]

@soycastic Nope, nothing like that appears. Using the mac app downloaded from the App Store.

[Neil Sainsbury @superligious]

@soycastic Ok, had a play with it now...how can I change the color of just the selected text? eg. In your screenshots above you've got "GET BETTER RESULTS" and "RESULTS" is a different color ~ perhaps I'm an idiot but I can't figure out how to do that.

[Neil Sainsbury @superligious]

@wcandillon https://t.co/xhbg3aSr4k

The classic! I’ve continually had it recommended to me for years now and just never found the time. Essentially derives how/why PBR rendering works etc. I think you would love it.

[Neil Sainsbury @superligious]

Just about to start my work-through of the classic Physically Based Rendering book ~ I want to implement everything from scratch in C++. Fairly intimidating...but I just recently finished Papa Rudin after 9+ months of continuous work so I have a thick skin at this point :-)

[Neil Sainsbury @superligious]

@thenoumenon Saw something like this just the other day actually: https://t.co/5shwPZ0guE !
