Functions

double lsst::sphgeom::getMinSquaredChordLength (Vector3d const &v, Vector3d const &a, Vector3d const &b, Vector3d const &n)
 Let p be the unit vector closest to v that lies on the plane with normal n in the direction of the cross product of a and b.
 
double lsst::sphgeom::getMaxSquaredChordLength (Vector3d const &v, Vector3d const &a, Vector3d const &b, Vector3d const &n)
 Let p be the unit vector furthest from v that lies on the plane with normal n in the direction of the cross product of a and b.
 
Angle lsst::sphgeom::getMinAngleToCircle (Angle x, Angle c)
 getMinAngleToCircle returns the minimum angular separation between a point at latitude x and the points on the circle of constant latitude c.
 
Angle lsst::sphgeom::getMaxAngleToCircle (Angle x, Angle c)
 getMaxAngleToCircle returns the maximum angular separation between a point at latitude x and the points on the circle of constant latitude c.
 
Vector3d lsst::sphgeom::getWeightedCentroid (UnitVector3d const &v0, UnitVector3d const &v1, UnitVector3d const &v2)
 getWeightedCentroid returns the center of mass of the given spherical triangle (assuming a uniform mass distribution over the triangle surface), weighted by the triangle area.
