Algorithm (Workflow)
This function, VLFLofPatch, is designed to extract the vertex list (VL) and facet list (FL) from a graphical object, specifically a patch object, in MATLAB. It is part of the SG-Library and was created by Tim Lueth in 2012.
Input Parameters
- h: This is the current object from which the vertex and facet lists are to be extracted. If not provided, the function defaults to using the current axes' patches (gca).
Output Results
- VL: The vertex list of the patch object.
- FL: The facet list of the patch object.
- h: The current object being processed.
Algorithm Steps
- The function begins by setting the variable
h to the current object of the current figure using get(gcf,'currentobject').
- If an input argument is provided, it overrides the default and sets
h to the first input argument.
- The function checks if the type of
h is 'patch' using strcmp(get(h,'Type'),'patch').
- If
h is a patch object, it retrieves the facet list using get(h,'Faces') and the vertex list using get(h,'Vertices').
- If
h is not a patch object, it sets VL and FL to empty arrays and h to 0.
