NAME    [Toc]    [Back]

     crv - draws a curve

C SPECIFICATION    [Toc]    [Back]

     void crv(points)
     Coord points[4][3];

PARAMETERS    [Toc]    [Back]

     points    expects an array	containing the four points that	define the
	       curve. The routine expects 3-D points (x, y, and	z coordinates
	       for each	point).

DESCRIPTION    [Toc]    [Back]

     crv draws a cubic spline curve segment (defined by	the four submitted
     points) according to the current curve basis and precision.

     The curve segment is approximated by a sequence of	straight lines.	 All
     lines use the current linestyle, which is reset prior to the first	line
     and continues through subsequent lines.  Other line modes,	including
     depthcueing, line width, and line antialiasing, also apply	to the lines
     generated by crv.

     After crv executes, the graphics position is undefined.
