JuliaCon2023

Hi! I will give a presentation at JuliaCon2023 at MIT. Creating smooth surface models with ElasticSurfaceEmbedding.jl JuliaCon 2023 My talk is about creating smooth surfaces by weaving paper strips. Please come to the event and love the Julia language and smooth surfaces!

Weaving Stereographic Projection

I made a stereographic projection by weaving paper strips! Here’s a Julia package for the computation of the shapes of the paper strips. GitHub - hyrodium/ElasticSurfaceEmbedding.jl: The weaving paper strips: shape optimization by geometric elasticity Japanese blog post about this: https://note.com/hyrodium/n/n7b7cf03a7d91
