Polygon_Volu

Example

a normalized unit square can be define as:
	(-1, -1, 0, 5, 1.0)
	(-1,  1, 0, 5, 1.0)
	( 1,  1, 0, 5, 1.0)
	( 1, -1, 0, 5, 1.0)
	(-1, -1, 0, 5, 1.0)
	Input Data: Field 1-D 4-Space 1-Vector IRREGULAR
                    Colormap (Optional)
	Output data: Geom
	Parameter:
	Number steps:	Number of maximum colors used
	Low data value:	lower color range
	High data value:Higher color range
	INPUT x min:	SW X cornor of the "show box"
	INPUT x max:	NE X cornor of the "show box"
	INPUT y min:	SW Y cornor of the "show box"
	INPUT y max:	NE Y cornor of the "show box"
	Z Scale:	Scale apply to z direction
	Wrap Around:	To specify the "wrap around" of the polygonal volume
	zchoice:	To choice the method for polygonal volume's height
	uniform color:	To set the polygonal volume's color mapping scheme
	Uniform color R:
	Uniform color G:
	Uniform color B:
			To set uniform color for every polygons
