After quantifying the discrepancies, I need to reveal uncomfortable truths about geometry to budget unavoidable distortion. But… ## [Interpolation Tribunal](https://geekshavefeelings.com/posts/2026/interpolation-tribunal/) _2026-04-17 · geeks have feelings_ Series index: Part I , Part II (this post) , Part III Shared-edge “Vernier” comparison: midpoint and one-pass subdivision techniques place boundary vertices at different positions. In Part I , midpoint recursion and one-pass 1 / n refused to line up at equal triangle count. The mismatch pattern was suspiciously structured, suggesting distortion in the algorithms themselves \* . Derp lerp § Remember… ## [Better-er Spheres, Fewer-er Triangles](https://geekshavefeelings.com/posts/2026/better-er-spheres-fewer-er-triangles/) _2026-04-08 · geeks have feelings_ Series index: Part I (this post) , Part II , Part III Back in 2009 I wrote a post about icospheres . It ended, “To be completed….” Completing it now. The case for icospheres § It might be easier for us thinkmeats to imagine UV spheres : globes with latitudes and longitudes. But for silicon, or at least rasterizing \* GPU s, an icosahedron better approximates a sphere with fewer triangles (20 to be… ## [SSH into Windows 11 WSL2 with Agent Forwarding](https://geekshavefeelings.com/posts/2025/ssh-into-wsl2-with-agent-forwarding/) _2025-12-14 · geeks have feelings_ Jump to Recipe ↓ You’ll SSH into WSL 2 through Windows with ProxyJump , forward your SSH agent end-to-end, and keep your GitHub SSH key on your laptop (or somewhere even safer!). SSH SSH I have a confession: I’m a Windows noob. I want to keep my PC ’s Windows 11 installation as “stock” as possible. I’ve worked with enough computers to know that fixing computers as an engineer is the optimal method…
