Function Documentation

double geometry::area (  Vertex *  p1, Vertex *  p2, Vertex *  p3 )

Calculate area of triangle (p1/p2/p3). Version: 16 jul 2002 Date: 16 jul 2002 Definition at line 16 of file geometry.cpp. References Vertex::x(), and Vertex::y(). Referenced by DelaunayMeshGenerator::generate().

double geometry::distance (  const line &  l, const point &  p )

Get distance of point to line. Version: 17 jul 2002 Date: 17 jul 2002 Definition at line 39 of file geometry.cpp. References distance(), geometry::line::p1, geometry::line::p2, geometry::point::x, and geometry::point::y.

double geometry::distance (  const point &  p1, const point &  p2 )

Calculate distance from point p1 to point p2. See also: distance(double, double, double, double); Definition at line 30 of file geometry.cpp. References geometry::point::x, and geometry::point::y. Referenced by distance(), and intersect().

bool geometry::intersect (  const line &  l1, const line &  l2 )

Test intersection of lines l1 and l2. Returns: true if lines intersect, false if lines do not intersect. Definition at line 55 of file geometry.cpp. References distance(), geometry::line::p1, geometry::line::p2, geometry::point::x, and geometry::point::y.
