9.23 BezierCurve -- Bezier curve

class BezierCurve( name = "BezierCurve",
pnts = None,
closed = False,
epsilon = 0.01,
subdiv = 4,
show_tangents = False,
curvegeom = None
)

pnts is a list of BezierPoint objects (see section 10.9).

If closed is set to True the last point will be connected to the first point.

epsilon is a threshold value that determines the accuracy of length calculations of the curve.

subdiv is the number of subdivisions that are made to draw the curve using OpenGL.

If show_tangents is set to True the OpenGL visualization will also show the in and out tangents.

You can also pass a previously created BezierCurveGeom object via the curvegeom argument. In this case, the arguments pnts, closed, epsilon, subdiv and show_tangents are ignored.
