Is Marching Cubes not already outdated algorithm to do this !?

Why not use state pf the art algorithm for this, like Marching Tiles ?

For few other approaches implemented for WebGL see here:

Marching cubes is 3d isosurface reconstruction, and recently it has become un-patent encumbered, so there's a new rennaisance of usage.

From my google searches, all I can find on "Marching tiles" is a bunch of 2d stuff. Hardly state of the art...

Can you direct me to what you meant when you said state of the art?
