Curve Operations

The functions available fall into four distinct groups,

1)	Separate functions involving two groups of curves, where the result is of the form:
	<Rn> = <G1n> [OP] <G2n>
2)	Separate functions involving only one group of curves, where the result is of the form:
	<Rn> = [OP] <G1n>
3)	Single output from only one group of curves, where the result is of the form:
	<R> = [OP] <G1(1...n)>
4)	Separate functions involving three groups of curves, where the result is of the form:
	<Rn> = <G1n> [OP] <G2n>[OP] <G3n> Currently the only function that has 3 curves groups as input is the VEC operation

1) Separate Functions On Two Groups These functions display a menu in which two groups of curves may be selected, (see right). You must define one or more curves in group #1, and group #2 must be:
either	A group of as many curves as there are in group #1.
or	A single curve. Every curve in group #1 is applied to this curve.
or	A constant value, entered in the Key in : text box.
You can pick curves in either group from their menus, or type a range into the Key in: box. NOTE : the order in which they are processed is ascending sequential, not the order in which you define them .

2) Separate Functions On A Single Group

These functions display a menu in which one group of curves may be selected, (see right).

Operations apply separately and uniquely to each selected curve.

As before, the order of processing is ascending sequential, not the order in which you define them.

3) Single Output From A Single Group

These functions require a single group of curves as input like the functions above. The output is a single curve.
