Algorithm (Workflow)
This function, SGinspect, is designed to zoom in and inspect specific vertices or facets of a solid geometry object. It is part of the SolidGeometry library and was introduced in version 4.4.
Input Parameters
- SG: Represents the solid geometry object containing vertex and facet information.
- vi: A list of vertex indices that the user wants to inspect.
- fi: A list of facet indices that the user wants to inspect.
Algorithm Steps
- Retrieve the vertex indices (
vi) and facet indices (fi) from the input parameters using the getfuncparams function.
- Ensure that the vertex indices are in column format. If they are not, transpose them.
- Initialize an empty list
VL to store the vertices to be inspected.
- If vertex indices are provided, append the corresponding vertices from
SG.VL to VL.
- If facet indices are provided, append the vertices corresponding to these facets from
SG.FL to VL.
- Call the
zoompatch function with VL and two scaling factors (0.01, 0.01) to zoom into the specified vertices and facets.
- Plot the vertices in
VL using the VLplot function with red asterisks ('r*').
- Determine the edges of the specified facets using the
ELofFL function.
- Plot the edges using the
VLELplots function with green lines ('g-') and a line width of 2.
