Rendering.NET allows you to create a model with simple define a function that generate the vertices.

Two ways of specifying a sphere surface:

by a curve of a circumference prolonged among the y-axis and scaled with a semi circumference function

by mapping the quad surface to the sphere surface using u and v as parameters

Two ways of specifying a sphere surface:

var sphere1 = new ManifoldModel( Manifold .Curve(t => new Vector3(GMath.cos(2 * PI * t), 0, GMath.sin(2 * PI * t))) .Promote((p, u) => p * GMath.sqrt(1 - GMath.sqr(1 - 2 * u)) + new Vector3(0, 1 - 2 * u, 0)), 32, 32);

by mapping the quad surface to the sphere surface using u and v as parameters

var sphere2 = new ManifoldModel( Manifold.Surface((u, v) => { float radius = GMath.sqrt(1 - GMath.sqr(2 * u - 1)); return new Vector3(radius * GMath.sin(2 * PI * v), 2 * u - 1, radius * GMath.cos(2 * PI * v)); }), 32, 32);
