Constructor & Destructor Documentation

LagrangeCurve1::LagrangeCurve1	(	pMeshEnt	in_vtx1,
		pMeshEnt	in_vtx2
	)

input is an ordered pair of mesh vertices, which defines the direction pointing from xi1 to xi2 in the barycentric coodinate system.

Member Function Documentation

int LagrangeCurve1::v_eval ( Point1d  in_xi, Point3d &  out_xyz  )

protectedvirtual

input parametric coord is xi1, and value of xi1 goes from 1 to 0, from the left end of the curve to its right end

Implements ParametricCurve.
