Algorithm (Workflow)
This function, CPLfillinside, is designed to create a contour that fills another or several contours. It is part of the SolidGeometry library and was introduced in version 4.6. The function primarily operates similarly to CPLfillin.
Input Parameters
- CPL: A Closed Polygon List, which is the primary input representing the contours to be filled.
- Amin: The minimum surface area of interest. If not specified, it defaults to 9 mm², which corresponds to a 3x3 mm area.
- Asam: The percentage of the maximum area to consider. The default value is 0.9, representing 90% of the maximum area.
Output
- CPLN: The resulting inverse polygon after processing the input contours.
Algorithm Steps
- Initialize
Amin to 9 if not provided, ensuring it represents the minimal size of an accepted surface.
- Initialize
Asam to 0.9 if not provided, representing the percentage of all similar surfaces to consider.
- Call the function
CPLfillin with the input CPL and any additional arguments to generate an intermediate contour list CPLI.
- Use the function
CPLbool with the '+' operation to combine the original CPL with CPLI, resulting in CPLN.
- If no output is requested (
nargout==0), visualize the result using SGfigure and plot the resulting contour CPLN in green and the original CPL in red.
Example Usage
The function can be used with sample data as follows:
CPLfillinside(CPLsample(14));CPLfillinside(CPLsample(19));CPLfillinside(CPLsample(21));
