#Manifold v3.1 is out! We now have a proper performance suite following EMBER's example, and have *doubled* our performance over v3.0. Also lots of improvements on decimation, properties, faces, and more: github.com/elalish/mani...

#Manifold v3.0 is out! This is a huge release - we have removed *all* required dependencies. Our npm package is half the size and twice the speed. Our #SDF LevelSet is much faster and higher quality. And so much more: github.com/elalish/mani...
