ABSTRACT:
A computer-implemented graphics program for drawing a spline. The spline is drawn using a first method in the graphics program. Thereafter, the graphics program seamlessly switches from drawing the spline using the first method to drawing the spline using a second method, in response to a first user command. Further, the graphics program may also seamlessly switch from drawing the spline using the second method to drawing the spline using the first method, in response to a second user command.
