TL;DR

The video explores the application of the marching squares algorithm to create contours and patterns in a two-dimensional scalar field using open simplex noise.

Transcript

welcome to another episode of coding in the Cabana today I am going to tackle something called marching squares the topic of marching squares are marching cubes was originally suggested for the coding train on February 18 2019 by Quinn the sunrise so I do want to try marching cubes I suppose that'll either be in a follow-up video whether it's a Cab...
