// .NAME vtkCylinder - implicit function for a cylinder
|
|
// .SECTION Description
|
|
// vtkCylinder computes the implicit function and function gradient for a
|
|
// cylinder. vtkCylinder is a concrete implementation of vtkImplicitFunction.
|
|
// Cylinder is centered at Center and axes of rotation is along the
|
|
// y-axis. (Use the superclass' vtkImplicitFunction transformation matrix if
|
|
// necessary to reposition.)
|
|
|
|
// .SECTION Caveats
|
|
// The cylinder is infinite in extent. To truncate the cylinder use the
|
|
// vtkImplicitBoolean in combination with clipping planes.
