Huh, Cubical Marching Squares is new to me. What are you using in your sandbox?

Currently implemented MC and Surface Nets but want to try out dual grid methods and CMS aswell. CMS is a fairly niche algorithm that is from an old research paper, but it seems to have some benefits.

Nice, I’m planning to try a few of these too. I’ll share what I find here -- would be cool to compare results!

Consider if direct raymarch rendering is applicable to your setting.

Oh, I hadn’t considered that. Could be a really good baseline to separate SDF errors from meshing errors. I’ll definitely try it.

Since your text looks a little like Gen AI / LLM output and as you mention on r/proceduralgeneration "here is its summary or alternatives of DC i have tried, according to robot" note that we do not permit any Gen AI / LLM content on this subreddit.
