8c. Control Points

Control points allow you to manipulate the shape and orientation of the currently selected curve. To activate the control points you must first choose a point then either press the Tab key or use the select curve tool to select a curve and the control points will appear when you press the control point button. Each control point controls the length of the curve on its side of the selected point. The shorter the control point line, the shorter the curve length and vise versa. The curve also follows the orientation of the control point line, if you move the control point up and left the corresponding curve will move up and left, but the control points for either curve of a point are on a straight line so the curve on the opposite side will go down (but not to the left, for the outward motion is independent of the other control point). However, clicking the independant control point tool will allow you to individually move the control points. Simulation of invisibility such as in the below example is just one use for control points.
