Dave2022, to girlyposting

Two days ago I posted a photo of the best Slime Molds I'd ever found.

Well, today I went back to revisit them. They'd gone from to

They were now even harder to photograph, it needed a near half second exposure under the gloomy log, but it was windy and they wouldn't keep still and kept giving off clouds of microscopic brown spores.

The Marching Cubes and Dual Contouring algorithms create meshes with triangles of very irregular sizes.

A "Compact Isocontours" technique by Moore and Warren in 1995 addressed this very nicely. The technique is described in Graphics Gems III and also here:

This was used in Spore's creature creator, but I can't find any open source implementations of it, and Asset Store solutions like MudBun and Clayxels don't support it either. Am I missing something?

@runevision An implementation part of the Lobster language seems to be the only reference to this paper on GitHub:

They also reference Chris Hecker's notes on :

Inert, sleeping 🦠 can survive for centuries, without nutrients, resisting heat, UV , antibiotics and other harsh chemicals. Switching on of metabolic processes after centuries of dormancy 💤. In response to nutrients, the conduit, a membrane channel, opens, allowing ions to escape from the interior. This initiates a cascade of reactions that allow the dormant cell to shed its protective armor and resume growth https://hms.harvard.edu/news/how-dormant-bacteria-return-life
