Algorithm (Workflow)
This function, PLBezierC, is designed to generate Bezier splines for a given open point list in 2D. It is part of the SolidGeometry library and was introduced in version 5.2. The function is similar to VLBezierC but specifically handles 2D output.
Input Parameters
- PL: A 2D point list that represents the input points for which the Bezier curve will be generated.
- k: An optional parameter that specifies the number of points on the Bezier curve. If not provided, the default is the number of points in
PL (i.e., size(PL,1)).
Output Results
- PL: A 2D point list representing the generated Bezier curve.
Algorithm Steps
- The function begins by calling
VLBezierC with the input point list PL and any additional arguments provided in varargin. This function generates a Bezier curve based on the input points.
- The result from
VLBezierC is stored in PLN.
- The function then extracts the first two columns of
PLN to ensure the output is a 2D point list.
- If no output argument is specified (i.e.,
nargout==0), the function will plot the original point list PL in red and the generated Bezier curve PLN in green using the SGfigure and PLplot functions.
Example Usage
An example call to the function is PLBezierC(PLsample(6),12), which generates a Bezier curve with 12 points from a sample point list of 6 points.
