Tetrahedron
public Tetrahedron()
Create a regular tetrahedron with its center at the origin, having edge length2*sqrt(2), and with its vertices at corners of the cube with vertices(±1, ±1, ±1).
-
Tetrahedron
public Tetrahedron(boolean dual)
Create a regular tetrahedron or its dual tetrahedron (the dual of a tetrahedron is another tetrahedron).https://en.wikipedia.org/wiki/Tetrahedron#Regular_tetrahedron
The combination of these two dual tetrahedrons is a stellated octahedron.
- Parameters:
dual- choose between the two dual tetrahedrons
-
Tetrahedron
public Tetrahedron(int n1, int n2)
Create a regular tetrahedron with its center at the origin, having edge length2*sqrt(2), and with its vertices at corners of the cube with vertices(±1, ±1, ±1).Add line segments fanning out from each vertex to its opposite edge.
- Parameters:
n1- number of lines fanning out from v0 and v1 towards the edge (v2, v3)n2- number of lines fanning out from v2 and v3 towards the edge (v0, v1)- Throws:
IllegalArgumentException- ifn1is less than 0IllegalArgumentException- ifn2is less than 0

Tetrahedron
public Tetrahedron(int m0, int m1, int m2, int m3)
Create a regular tetrahedron with its center at the origin, having edge length2*sqrt(2), and with its vertices at corners of the cube with vertices(±1, ±1, ±1).Add line segments fanning out from each vertex onto its three adjacent sides.
- Parameters:
m0- number of lines fanning out from v0 onto each adjacent side of the tetrahedronm1- number of lines fanning out from v1 onto each adjacent side of the tetrahedronm2- number of lines fanning out from v2 onto each adjacent side of the tetrahedronm3- number of lines fanning out from v3 onto each adjacent side of the tetrahedron- Throws:
IllegalArgumentException- ifm0is less than 0IllegalArgumentException- ifm1is less than 0IllegalArgumentException- ifm2is less than 0IllegalArgumentException- ifm3is less than 0
