Algorithm (Workflow)

This function, appuireadSTL, is designed to read an STL file and visualize its contents using the SolidGeometry (SG) library. Below is a detailed explanation of the algorithm and its parameters:

Input Parameters

Algorithm Steps

  1. The function begins by calling VLFLui, which is responsible for loading the vertex list, face list, filename, and pathname from a user interface. This function returns the values to SG.VL, SG.FL, fname, and pname.
  2. It checks if SG.VL is not empty, indicating that the STL file was successfully loaded.
  3. If the vertex list is not empty, the current figure is brought to the foreground using figure(gcf).
  4. The current axes are deleted using delete(gca) to prepare for new data visualization.
  5. The user data of the current figure is set to SG using set(gcf,'UserData',SG), storing the geometry data within the figure.
  6. The function VLFLplot is called with parameters SG.VL, SG.FL, and 'm' to plot the geometry in magenta color.
  7. The title of the plot is set to the filename using title(fname).
  8. Lighting is added to the plot using VLFLplotlight with parameters (1,1) and (0,0.9) to enhance the visualization.

The function does not have any switch conditions, and it primarily focuses on loading and visualizing STL files using the SG library.
