Weekend Reading: Terrain Mesh, Designing on a Deadline, and Bookshelves
🏔 MARTINI: Real-Time RTIN Terrain Mesh
Some cool work from Vladimir Agafonkin on a library for RTIN mesh generation, with an interactive notebook to experiment with it on Observable:
An RTIN mesh consists of only right-angle triangles, which makes it less precise than Delaunay-based TIN meshes, requiring more triangles to approximate the same surface. But RTIN has two significant advantages:
- The algorithm generates a hierarchy of all approximations of varying precisions — after running it once, you can quickly retrieve a mesh for any given level of detail.
- It’s very fast, making it viable for client-side meshing from raster terrain tiles. Surprisingly, I haven’t found any prior attempts to do it in the browser.
👨🏽🎨 Design on a Deadline: How Notion Pulled Itself Back from the Brink of Failure
This is an interesting piece on the Figma blog about Notion and their design process in getting the v1 off the ground a few years ago. I’ve been using Notion for a while and can attest to the craftsmanship in design and user experience. All the effort put in and iterated on really shows in how fluid the whole app feels.
📚 Patrick Collison’s Bookshelf
I’m always a sucker for a curated list of reading recommendations. This one’s from Stripe founder Patrick Collison, who seems to share a lot my interests and curiosities.
