Although curves cannot be shaded or rendered, they are used by other Advanced Visualizer programs. u0 is the starting parameter value for the curve. This is a floating point number. u1 is the ending parameter value for the curve. This is a floating point number.

WebWavefronts are surfaces connecting points with the same phase of a monochromatic wave. For example, one may select all those points where the maximum of the oscillating quantity within an oscillation cycle (for example, the maximum air pressure for a sound wave or the maximum positive electric field strength for an optical wave) is reached.
