B-Splines bezier
See also: Splines by interpolation, Splines by control points, B-Spline from scattered points , Convert into b-spline.
Menu access : Curves | Splines
Description:
Creates a spline curve constraint by its control points, using a Bezier algorithm.
The difference of this curve with the other ones is that on Bezier case the move of one point will influence the complete curve.
The degree of the resulting curve is the number of points minus 1.
General philosophy:
Choose BEZIER in the list
Select the curve starting point.
Select the different control points.
Select on the STOP button when the last point is selected.
Example(s):
Specific point(s):
You can select a point several time
in order to raise the influence of this point on the curve.
Thanks to the function "Edit | Insert", you can dynamically
insert a knot or a point into
a basic b-spline.
Insert= POINT allows to insert a new point and modify the b-spline geometry.
Insert= KNOT allows to insert a new point without modifying the actual b-spline geometry.
Available modification(s):
The 
icon allows you
to move a point of the curve or the curve itself.
The 
icon allows you
to change the influence on the curve of a specific point.
