FirstParameter

Returns: The parameter value at one end of the Edge. Not necessarily at Vertex[0]. See Parametric Equations

LastParameter

Returns: The parameter value at the other end of the Edge. Not necessarily at Vertex[1].

getParameterByLength(Float)

Description: Maps the interval [0,Length] to the interval [FirstParameter,LastParameter]

Returns: Float

valueAt(Float)

Description: Returns the 3D vector corresponding to a parameter value.

Returns: Vector

parameterAt(Vertex,[Face])

Description: Returns the parameter value corresponding to a Vertex (3D point).

Returns: Float

tangentAt(Float)

Description: Returns the direction vector of the tangent to the edge at a parameter value (if it exists).

Returns: Vector

normalAt(Float)

Description: Returns the direction vector of the normal to the edge at a parameter value (if it exists uniquely).

Returns: Vector

curvatureAt(Float)

Description: Returns the curvature of the edge at a parameter value.

Returns: Float

centerOfCurvatureAt(Float)

Description: Returns the center (3D point) of the osculating circle at a parameter value.

Returns: Vector
