IMP::algebra::Cone3D Class Reference

---

Detailed Description

In general, a cone is a pyramid with a circular cross section. A right cone is a cone with its vertex above the center of its base. However, when used without qualification, the term "cone" often means "right cone." We have implemented a "right cone".

Note:

This class is a geometric primitive. Also, this class is not not initialized by its default constructor.

Vector Generators
These functions generate vector objects. Some of the methods, those with random in their name, generate a single vector chosen uniformly from the specified domain. Others, the cover methods, generate a set of points distributed (somewhat) evenly over the domain.

double IMP::algebra::Cone3D::get_angle

(

)

const

The opening angle of a cone is the vertex angle made by a cross section through the apex and center of the base.

Plane3D IMP::algebra::Cone3D::get_base_plane

(

)

const

Get the plane supporting the base of the cone.

The cone is on the positive side of the plane.

VectorD<3> IMP::algebra::Cone3D::get_direction

(

)

const

Get the direction of the axis of the cone.

This vector points from the tip into the occupied volume.
