This applet is both a 3D parametric curve grapher and an applet that illustrates the velocity and the acceleration vectors in 3D. The user enters parametic formulas for the x, y, and z coordinates in terms of the parameter t. The applet plots the corresponding curve. The curve can be traced while the velocity and the acceleration vectors are displayed together with their approximate values. The curve can be rotated in real time with the mouse.

Note: The complete source code for the applet is available in one of our AS3 tutorials: Motion in 3D in the Advanced and Experimental AS3 tutorials section of Flash and Math.
