includes main-level programReturns the Bezier curve between points.
Examples
Try the main-level example program at the end of this file:
IDL> .run vis_bezier
Routines
result = vis_bezier_binomial(n)Computes the binomial coefficients for a given degree.
result = vis_bezier(x, y [, z] [, n_points=long])Returns the Bezier curve between points.
Routine details
top vis_bezier_binomial
result = vis_bezier_binomial(n)
Computes the binomial coefficients for a given degree.
Return value
fltarr(n + 1L)
Parameters
- n in required type=long
degree of binomial coefficients, 0, 1, 2, ... n
top vis_bezier
result = vis_bezier(x, y [, z] [, n_points=long])
Returns the Bezier curve between points.
The returned Bezier curve will go through the first and last points, but the intermediate points only indicate shape and direction so the curve is not guaranteed to pass through them.
Return value
fltarr(2, npoints)
Parameters
- x in required type=fltarr(n)
x-coordinates of control points
- y in required type=fltarr(n)
y-coordinates of control points
- z in optional type=fltarr(n)
z-coordinates of control points
Keywords
- n_points in optional type=long default=20L
number of points
