ofxAddons
Metaballs implementations for openFrameworks using marching cubes and marching tetrahedrons.
Forks
Forks pushed to more recently than kylemcdonald/ofxMetaballs itself, plus any admin-confirmed fork with commits of its own — worth checking if you're hitting issues with the original.
README
ofxMetaballs is an addon for openFrameworks
It's still heavily a work in progress, as it consists of two completely separate implementations that are only informally linked. In the future they should either extend a base class or be modes of a single class. There are also some slight differences in the way MC handles minRadius/maxRadius compared to MT.
The primary differences between MT and MC are:
MT can always be 3d printed, while MC isn't always manifold or even oriented uniformly. MC is generally faster than MT.
- MC internally uses a -1 to +1 domain, while MT uses 0 to 1, but generally shouldn't be an issue for the user as all data should be normalized to 0 to 1 before being fed into MC/MT.
