Algorithm (Workflow)

The function SGplot4 is designed to plot a solid geometry object in four different views using MATLAB. It is part of the SolidGeometry library and is used for visualization purposes.

Input Parameters

• SG: This is the solid geometry object that you want to visualize. It contains the geometric data necessary for plotting.
• varargin: This allows for additional optional parameters to be passed to the function, which are then forwarded to the SGplotalpha function. These parameters can be used to customize the appearance of the plots, such as color or transparency.

Function Workflow

1. The function begins by calling SGfigure, which likely sets up a new figure window for plotting.
2. The plotting area is divided into a 2x2 grid using the subplot function, allowing for four separate plots within the same figure.
3. Each subplot is configured to display the solid geometry from a different viewpoint:
   • subplot(2,2,1); view(90,0); - This sets the first subplot to show a side or left view of the solid.
   • subplot(2,2,2); view(0,0); - This sets the second subplot to show a side or front view of the solid.
   • subplot(2,2,4); view(0,90); - This sets the fourth subplot to show a top view of the solid.
   • subplot(2,2,3); view(30,30); - This sets the third subplot to show a 3D perspective view of the solid.
4. In each subplot, the SGplotalpha function is called with the solid geometry and any additional parameters. This function is responsible for the actual rendering of the solid in the specified view.
5. Each subplot is given a title corresponding to the view it represents (e.g., "side/left", "side/front", "top", "3D").

The function does not return any values; its purpose is solely to create a visual representation of the solid geometry in multiple views.
