Detailed Description

utility class for calculating intersection points between geometry primitives

Member Function Documentation

closestPt()

static rw::math::Vector3D<double> closestPt ( const rw::math::Vector3D< double > &  point, const Line &  line  )

static

closest point tests

finds the point on a line which is closest to the point point

intersetPtRayPlane()

static bool intersetPtRayPlane ( const rw::math::Vector3D< double > &  p1, const rw::math::Vector3D< double > &  p2, const Plane &  p, rw::math::Vector3D< double > &  dst  )

static

finds the point on a line which is closest to the point point

closest point pair tests

finds the closest points between two line segments

finds the closest points between a line segment and a triangle

finds the closest points between a ray and a triangle intersection tests

calculates the intersection point between the ray and the plane. If they intersect true is returned and intersection point is set in dst

intersetPtTriTri()

static bool intersetPtTriTri ( const rw::geometry::Triangle< double > &  triA, const rw::geometry::Triangle< double > &  triB, rw::math::Vector3D< double > &  dst1, rw::math::Vector3D< double > &  dst2  )

static

calculates the intersection point between the triangle triA and the triangle triB. If they intersect, true is returned and two intersection points are set in dst1 and dst2

Note

this is not an optimized method
