Rotation via Double Reflection

While studying Geometric Algebra I have built some interactive visualization to demonstrate how geometric transformations (rotation, scaling, translation) can be constructed by just composing reflections. Accepting reflection as the most elementary geometric operation was an eye opening moment for me. I think some of you might enjoy the interactive visuals.

In plain words

Rotation via Double Reflection is an interactive visualization tool that demonstrates how geometric transformations—rotation, scaling, and translation—can be constructed through composed reflections. Designed for students and enthusiasts of geometric algebra, it presents reflection as the fundamental geometric operation underlying these transformations. The tool provides hands-on visual exploration of these mathematical concepts.

    I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

    Visualizing the math that powers 3D character animation2022 · diegomacario.github.io · ▲238

    Hi everyone! I'm the author of this project. I wrote it because I think that the math that makes characters move in games and movies is incredibly beautiful, and I wanted to give others a glimpse into it. It's crazy to think that quaternions, an abstract mathematical tool discovered by William Rowan Hamilton in 1843, would be so perfectly suited to solve hard problems in the world of 3D character animation more than a hundred years later. The story of how he discovered quaternions is also beautiful. Here's an excerpt from Wikipedia: "Hamilton was looking for ways of extending complex numbers…

  • Visualize rotating objects from the 4th, 5th, nth dimensions2023 · ncube.ndavd.com · ▲181

    Ever since I remember I had a lot of curiosity regarding hyper dimensional spaces. Picturing higher dimensions, such an impossible yet exciting idea... So years ago I came across a small GIF of a tesseract. Since then it left me wondering how cubes from even higher dimensions would look like... Years passed and I became a software developer, decided to tackle the problem myself and ncube was the result. ncube allows you to visualize rotating hypercubes of arbitrary dimensions. It works by rotating the hyperdimensional vertices and applying a chain of perspective projections to them until the…

  • Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  • Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
