Monte Carlo integration lets us integrate high-dimensional functions exponentially faster than traditional methods! Part two (thenumb.at/Monte-Carlo/) explores how and why it works.

I'm working on a series of posts about Monte Carlo methods! The first (thenumb.at/Probability/) is a review/overview of continuous probability, including random variables, distributions, expectation, variance, probability bounds, and the Dirac delta.

Here comes another patch 💌 it brings a few QoL things: * Option to remove merlons and railings - no more need to stack two blocks to get rid of 'em 😄 * Last color/style edit is remembered, and applied to the next shape, wall, window, etc you create. * a few misc fixes! 🧵

After fifteen years of working on products for our clients, we’re releasing one of our very own! Rowboat is our tool for quickly making sense of tabular data (think Excel and CSV files). It runs entirely in the browser, just rowboat.xyz and drop a file on the page.

At @Apple we’ve been working on some cool tooling for ML. Check out the Mycelium graph viewer and also @donghaoren’s tensor visualizer widget at github.com/apple/tensor-visu…
Excited to share: my team@Apple @_jgoertler open-sources Mycelium - performant graph viewer in Talaria (CHI best paper nominee)! Mycelium quickly renders thousands of nodes with smooth interaction. Highly customizable for your need. Try our demo & repo: apple.github.io/ml-mycelium/

Code has been added to geometry-central (geometry-central.net)! Demo projects here: github.com/nzfeng/signed-hea… github.com/nzfeng/signed-hea…

Signed distance functions (SDFs) are fundamental tools in graphics, vision, and physics simulation. But how do you get a high-quality SDF from messy, real-world input? At #SIGGRAPH2024, we introduced a simple method for turning "broken" geometry into a well-behaved SDF. <🧵>

shader programming is for when off-by-1 errors just aren't doing it for you anymore, and you're looking to get into new things like • off by 1/2 • off by multiple of -1 • off by power of 2 • off by a reflection around 1/2 • off by 1 graphics api
