Computational geometry
template<class real_type >
real_type	ttl_util::scalarProduct2d (real_type dx1, real_type dy1, real_type dx2, real_type dy2)
	Scalar product between two 2D vectors.
template<class real_type >
real_type	ttl_util::crossProduct2d (real_type dx1, real_type dy1, real_type dx2, real_type dy2)
	Cross product between two 2D vectors.
template<class real_type >
real_type	ttl_util::orient2dfast (real_type pa[2], real_type pb[2], real_type pc[2])
	Returns a positive value if the 2D nodes/points pa, pb, and pc occur in counterclockwise order; a negative value if they occur in clockwise order; and zero if they are collinear.
Utilities involving points
template<class PointType >
vector< PointType * > *	ttl_util::createRandomData (int noPoints, int seed=1)
	Creates random data on the unit square.
