An actual Grid 2 Sphere...

I have made a 3D grid of points and tell the page to show all points inside a sphere inside the box of grid points. Now that I have restricted this to points which are inside but adjacent to outside points, I will start building edges and triangles.
(The red dots are farther away and should be smaller, but I made them bigger to make them visible. Also, please click in the box! 8-)
