/**
|
|
* @class vtkCone
|
|
* @brief implicit function for a cone
|
|
*
|
|
* vtkCone computes the implicit function and function gradient for a cone.
|
|
* vtkCone is a concrete implementation of vtkImplicitFunction. The cone vertex
|
|
* is located at the origin with axis of rotation coincident with x-axis. (Use
|
|
* the superclass' vtkImplicitFunction transformation matrix if necessary to
|
|
* reposition.) The angle specifies the angle between the axis of rotation
|
|
* and the side of the cone.
|
|
*
|
|
* @warning
|
|
* The cone is infinite in extent. To truncate the cone use the
|
|
* vtkImplicitBoolean in combination with clipping planes.
