The page generates a square grid which we turn into an octasphere, now that I have 'spherified' the coordinates (BTW, I've swapped the x coordinate for the z coordinate here).

Square to Octahedron
The page generates a square grid which we turn into an octasphere.
Square grid to octahedron to spherical polyhedron
The page generates a square grid which we will turn into an octasphere. The animation loops through the points to draw quads, then clears and starts over again. The next step is to subdivide each quad into a pair of triangles based on the 'New York Street Distance' of each vertex from the center of the grid. Each of the two triangles has either the nearest or farthest vertex for each of the quads.

Cross And Dot Product
The page generates three points of a triangle or the endpoints of two vectors. Vector 1 is P0 to P1, Vector 2 is P0 to P2. You can then click in the blue box near the point you want to move (You need to move it in steps instead of grabbing and dragging it).
