Member Function Documentation

const Point & Shape::center ( ) const [inline]

access to center data member. Definition at line 65 of file Shape.h. Referenced by Cone::Cone(), Cons::Cons(), Hype::Hype(), Sphe::Sphe(), Tubs::Tubs(), Hexahedron::addPlane(), Tube::calculateSurfaces(), and Volume::distanceToEnter().

Shape & Shape::copy ( ) const [virtual]

non-virtual subclasses figure out how to return a copy. Definition at line 13 of file Shape.cxx.

virtual double Shape::distanceToEnter ( const Ray & r, double maxStep = FLT_MAX ) const [pure virtual]

Reimplemented in Volume.

double Shape::distanceToLeave ( const Ray & r, double maxStep = FLT_MAX ) const [pure virtual]

return the distance along the Ray to leave (if inside ), or enter (if outside). Can be negative if the origin of the Ray is close to the surface. maxStep is the largest distance required. returns FLT_MAX if no intersection Reimplemented in Volume.

int Shape::getBoundaryIndex ( const Point & p ) const [inline, virtual]

allows client using distanceToLeave to associate an index with a boundary, identified by the point. Reimplemented in Volume. Definition at line 45 of file Shape.h.

double Shape::getMaxDimension ( ) const [inline, virtual]

should be calculated by a subclass which is meant to be the maximum distance from the center. Reimplemented in Volume. Definition at line 51 of file Shape.h.

int Shape::inside ( const Point & x ) const [pure virtual]

is the point inside the volume? Reimplemented in Volume.

int Shape::lastBoundaryIndex ( ) const [inline, virtual]

distanceToLeave sets index of left boundary: client can use. Reimplemented in Volume. Definition at line 48 of file Shape.h.

void Shape::printOn ( std::ostream & os ) const [virtual]

print info about this object. Reimplemented from GeomObject. Reimplemented in Cone, Cons, Hype, Sphe, Trap, Trd1, Trd2, Tube, Tubs, and Volume. Definition at line 25 of file Shape.cxx. Referenced by Volume::printOn(), and Sphe::printOn().

GeomObject & Shape::transform ( const CoordTransform & T ) [virtual]

virtual method to perform transformations that must be implemented by subclasses. Reimplemented from GeomObject. Reimplemented in Volume. Definition at line 32 of file Shape.cxx. Referenced by Volume::transform().
