Description:
|
The second curve gives the direction at each point of the zero cross-section parameter (the u-direction), and the interval gives the parameter (angle) range required in the cross direction. The u-parameter increases clockwise around the spine direction for a positive radius (convex surface) and counterclockwise for a negative radius (concave surface).
