SubDCreateIcosahedron Method

Creates a SubD sphere based on an icosohedron (20 triangular faces and 5 valent vertices). This is a goofy topology for a Catmull-Clark subdivision surface (all triangles, all vertices have 5 edges). You may want to consider using the much behaved result from CreateSubDQuadSphere(sphere, vertexLocation, 1) or even the result from CreateSubDGlobeSphere().

Namespace:  Rhino.Geometry
Assembly:  RhinoCommon (in RhinoCommon.dll)
Since: 8.4
Syntax
Copy
public static SubD CreateIcosahedron(
	Sphere sphere,
	SubDComponentLocation vertexLocation
)

Parameters

sphere
Type: Rhino.GeometrySphere
Location, size and orientation of the sphere.
vertexLocation
Type: Rhino.GeometrySubDComponentLocation
If vertexLocation = SubDComponentLocation::ControlNet, then the control net points will be on the surface of the sphere. Otherwise the limit surface points will be on the sphere.

Return Value

Type: SubD
If the input parameters are valid, a SubD icosahedron is returned. Otherwise null is returned.
