crv(3G) crv(3G)
NAME
crv - draws a curve
C SPECIFICATION
void crv(points)
Coord points[4][3];
PARAMETERS
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
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.
