This method returns curvature information at a location on the edge.
Required arguments
- parameter
A Float specifying the normalized parameter location on the edge where the curvature is to be computed. This argument is mutually exclusive with the argument point.
- point
A tuple of X-, Y-, and Z-coordinates of a point at which the curvature is to be computed. If point does not lie on the edge an attempt is made to project it onto the edge and use the projected point.
Return value
A dictionary with keys 'evaluationPoint', 'curvature', 'radius', and 'tangent', where 'evaluationPoint' specifies the location at which the curvature was computed; 'curvature' specifies the curvature vector at that location; 'radius' is the radius of curvature; and 'tangent' specifies the tangent to the edge at that location.
Exceptions
The given edge is straight.
