Detailed Description

Define an infinite plane surface.

Inherits origin and constant normal from Surface. Interpret direction data member of Surface as a unit normal vector from the origin to the surface, has data member for magnitude, for efficiency

Constructor & Destructor Documentation

Plane::Plane ( const Point & o, const Vector & n )

constructor: origin is saved as a reference, n is the vector from the origin to the plane. Note that inside is defined as the side with the origin. second form is equivalent, but allows plane to pass through origin Definition at line 9 of file Plane.cxx.

Plane::Plane ( const Point & o, const Vector & n, double dist )

Definition at line 17 of file Plane.cxx.

Member Function Documentation

Surface & Plane::copy ( ) const [virtual]

make a copy, but using same origin. Reimplemented from Surface. Definition at line 44 of file Plane.cxx.

double Plane::distance ( const Point & x, const Vector & vhat, int inout ) const [virtual]

distance along direction v from point x to enter or leave the surface. Reimplemented from Surface. Definition at line 24 of file Plane.cxx. Referenced by Wedge::distance().

double Plane::how_near ( const Point & x ) const [inline, virtual]

define the geometry. Reimplemented from Surface. Definition at line 54 of file Plane.h. Referenced by Wedge::how_near(), and Wedge::normal().

const char * Plane::nameOf ( ) const [inline, virtual]

makes name available to subclasses using the type info facility. Reimplemented from GeomObject. Definition at line 44 of file Plane.h.

Vector Plane::normal ( const Point & x ) const [virtual]

returns normal-vector at Point x, assuming x to be on the plane. Reimplemented from Surface. Definition at line 38 of file Plane.cxx.

double Plane::offset ( ) const [inline, virtual]

Reimplemented from Surface. Definition at line 40 of file Plane.h.

void Plane::printOn ( std::ostream & os = std::cout ) const [virtual]

print info about this object. Reimplemented from GeomObject. Definition at line 49 of file Plane.cxx.

void Plane::reverse ( ) [virtual]

reverses sense of surface. Reimplemented from Surface. Definition at line 32 of file Plane.cxx.

void Plane::setOffset ( double offset ) [inline, virtual]

must be supplied by subclass if appropriate. Allows the surface to be "moved" by changing the parameter describing the offset of the surface from the origin. Reimplemented from Surface. Definition at line 39 of file Plane.h.
