Just got word that Humus has finished up his New Metaballs Demo!
This demo implements the marching cubes algorithm for constructing a polygonal model from an isosurface. The isosurface chosen here is a classical metaballs setup. Metaballs are defined by field function that's the sum of R2 / ((ball.x - x)2 + (ball.y - y)2 + (ball.z - z)2) for all balls. The surface is defined to be where the sum is one. The main bottleneck in this process is evaluating the field function. To speed things up a bit I implemented 3DNow and SSE versions of it as well. It should choose the most appropriate for your system as default. You can change what field function to use on the F1 menu.
