Detailed Description

template<int dim>
class ConeBoundary< dim >

Boundary object for the hull of a (truncated) cone with two different radii at the two ends. If one radius is chosen to be 0 the object describes the boundary of a cone. In three dimensions, points are projected on an arbitrarily oriented (truncated) cone described by the two endpoints and the corresponding radii. Similar to HyperBallBoundary, new points are projected by dividing the straight line between the old two points and adjusting the radius from the axis.

This class is derived from StraightBoundary rather than from Boundary, which would seem natural, since this way we can use the StraightBoundary::in_between() function.

As an example of use, consider the following code snippet:

Triangulation<dim> triangulation;
Point<dim> p1, p2;
p1[0] = -1;
p2[0] = 1;
const ConeBoundary<dim> boundary (1, 0.5, p1, p2);
triangulation.set_boundary (0, boundary);
triangulation.refine_global (2);

This will produce the following meshes after the two refinements we perform, in 2d and 3d, respectively:

Deprecated:
The boundary classes have been deprecated in favor of the more general Manifold classes. For this class CylindricalManifold is an appropriate replacement for spacedim==3, else StraightManifold can be used.

Constructor & Destructor Documentation

template<int dim>
ConeBoundary< dim >::ConeBoundary ( const double  radius_0,
const double  radius_1,
const Point< dim >  x_0,
const Point< dim >  x_1 
)

Constructor. Here the boundary object is constructed. The points x_0 and x_1 describe the starting and ending points of the axis of the (truncated) cone. radius_0 denotes the radius corresponding to x_0 and radius_1 the one corresponding to x_1.
