Web4 points (sphere) = 3 points (circle) + 1 point (center of sphere) 2nd Approach: Equation of sphere: ( x − a) 2 + ( x − b) 2 + ( x − c) 2 = R 2 You have 4 variables: a, b, c, R. So you need 4 equations (4 points) to determine a sphere.

The post above talks about some minor optimisations to improve the spacing, which I didn’t bother implementing. The next challenge is how to mesh these points. I’ve tried delaunay on the spiral result and then remap the mesh to the sphere points but this leaves a hole in the bottom. pray pray pray tshirt

A sphere (from Ancient Greek σφαῖρα (sphaîra) 'globe, ball') is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the centre of the sphere, and r is the … See more As mentioned earlier r is the sphere's radius; any line from the center to a point on the sphere is also called a radius. If a radius is extended through the center to the opposite side of the sphere, it creates a See more Enclosed volume In three dimensions, the volume inside a sphere (that is, the volume of a ball, but classically referred to as the volume of a sphere) is See more Circles Circles on the sphere are, like circles in the plane, made up of all points a certain distance from a fixed point on the sphere. The intersection of a … See more The geometry of the sphere was studied by the Greeks.
