title Constraint System dated Fall 2023 author Summary of work on relax-pk At the beginning of phase 2, we weren’t sure what to do about constraints. Based on past exploration, constraints seemed to hold a lot of promise but were notoriously unreliable. A good constraint system could unify and power a number of key aspects of the dynamic medium we seek. It would allow for mechanical constructions, like a rope and pulley, that feel physically correct. It would allow for a computational model tha

Jack Wallen / Elyse Betters Picaro / ZDNET One of the most important aspects of a desktop for me is efficiency. I need an OS that makes it easy to work with multiple windows open in a way that is effortless and painless. The MacOS desktop is an outstanding option for users of all types. It is elegant, simple to use, and rock solid. MacOS did not have built-in window snapping for the longest time, which was a glaring omission, especially given that most operating systems have had built-in windo

Why it matters: Quantum computers promise to tackle problems that stump even the most advanced supercomputers. Getting there is a different story, though. One of the biggest hurdles is efficiently connecting multiple quantum processors so they can share information without errors. A new interconnect device by MIT researchers could solve this problem. Current quantum-computing systems rely on clunky "point-to-point" connections, where data is transferred in a chain and has to jump between nodes.

The DDA Algorithm, explained interactively I've written a number of voxel raytracers, and all of them (all the good ones, at least) use the Digital Differential Analyzer Algorithm for raycasting. I've only ever "implemented" this algorithm once, by copying a reference somewhere. Since then, I've used and re-used that code. But I have something to admit: I've never really understood how it works. I've seen it explained well, explained poorly, explained on video, and still, I just don't get it. I

Measuring acceleration structures Hardware accelerated raytracing, as supported by DirectX 12 and Vulkan, relies on an abstract data structure that stores scene geometry, known as “acceleration structure” and often referred to as “BVH” or “BLAS”. Unlike geometry representation for rasterization, rendering engines can not customize the data layout; unlike texture formats, the layout is not standardized across vendors. It may seem like a trivial matter - surely, by 2025 all implementations are c

Actually drawing some ovals (that are not ellipses) Bruno Postle · Follow 4 min read · Feb 10, 2017 -- Listen Share In the last part I hopefully made it clear why you wouldn’t want to use an actual ellipse when making a real object, curves constructed from multiple fixed radius arcs are much more useful and look just the same. So there is a traditional draughting technique for drawing a five centred arch that makes quite a good imitation of an ellipse, here is the diagram again: This is fine,

The findings could help to explain the species’ fascinating flocking behaviour The CERN flock of sheep on site in 2017. (Image: CERN) Quantum entanglement is a fascinating phenomenon where two particles’ states are tied to each other, no matter how far apart the particles are. In 2022, the Nobel Prize in Physics was awarded to Alain Aspect, John F. Clauser and Anton Zeilinger for groundbreaking experiments involving entangled photons. These experiments confirmed the predictions for the manifes

Maju Kuruvilla, who left the CEO role of controversial one-click checkout startup Bolt last year, is back. He’s launching his own startup, focused on a different problem for online shoppers: what he calls “check-in.” When you click on an ad for something like a t-shirt, the experience afterwards can feel a little clunky. The website you land on might not even have the product you clicked on to begin with. That causes many shoppers to bounce back, hurting conversion rates, Kuruvilla told TechCru

Date Sun 09 March 2025 Tags Programming In this blog post, I’ll talk about smoothing and blurring 3D meshes using Laplacian mesh smoothing. A good example of where this is useful is Adobe Substance 3D Modeler’s smooth tool which I implemented using Laplacian mesh smoothing. Laplacian mesh smoothing works by iteratively shifting each vertex towards the average position of that vertex’s neighbors. The math formula for this is: $$v_i = \frac{1}{N} \sum_{j=1}^{N} v_j$$ which we can implement in c

My guide to hexagonal grids[1] is one of the most popular pages on my site. I keep a list of things I want to add to that page[2]. One of them has been spiral coordinate systems. I had thought I would wait until I actually use them in a real project, so that I would have real world experience with the thing I’m writing about. I’m afraid of writing about things I’m unsure about, or information that’s incomplete. But I haven’t used them yet. I decided to stop waiting. Spiral coordinates on a hex

Understanding Memory Management, Part 2: C++ and RAII This is the second post in my planned multipart series on memory management. In part I we covered the basics of memory allocation and how it works in C, where the programmer is responsible for manually allocating and freeing memory. In this post, we'll start looking at memory management in C++, which provides a number of much fancier affordances. As the name suggests, C++ is a derivative of C. The original version of C++ was basically an ob

Tangled is a new social-enabled Git collaboration platform, built on top of the AT Protocol. We envision a place where developers have complete ownership of their code, open source communities can freely self-govern and most importantly, coding can be social and fun again. There are several models for decentralized code collaboration platforms, ranging from ActivityPub’s (Forgejo) federated model, to Radicle’s entirely P2P model. Our approach attempts to be the best of both worlds by adopting a
