3.4.2 SCPLU/SCPLV

1.

Function

Draws a polyline in the U/V-coordinates.

2.

Call

CALL SCPLU(N,UPX,UPY,UPZ)
CALL SCPLV(N,VPX,VPY,VPZ)

3.

Explanation of Parameters

N	(I)	The length of array UPX, UPY, UPZ
UPX, UPY, UPZ	(R)	An array of length N. Gives the (X, Y, Z,) coordinates for the points of a polyline in UC.
VPX, VPY, VPZ	(R)	An array of length N. Gives the (X, Y, Z,) coordinates for the points of a polyline in VC.

4.

Notes

(a)

N must be larger than 2.

(b)

The attributes of the polyline are set by SCSPLI.
