Algorithm (Workflow)

The function appsavegcaSTL is designed to save the current figure in MATLAB as an STL file. It is part of the SolidGeometry library and was created by Tim Lueth. The function does not take any input parameters and operates on the current figure in MATLAB.

Input Parameters

There are no explicit input parameters for this function. It operates on the current figure, which is accessed using gcf (get current figure) in MATLAB.

Process

1. The function begins by calling VLFLofgca, which is assumed to extract vertex list (VL) and face list (FL) data from the current figure. This function is not defined in the provided code, but it is expected to return two outputs: VL and FL.
2. Next, the function VLFLwriteSTLb is called with VL and FL as arguments. This function is responsible for writing the vertex and face data to an STL file. The specifics of how this function operates are not provided, but it is assumed to handle the conversion and saving process.

Output

The function does not return any output to the MATLAB workspace. Instead, it writes the current figure's geometry data to an STL file, which is a common format for 3D models.

Assumptions

• The current figure contains valid geometry data that can be represented as a vertex list and a face list.
• The functions VLFLofgca and VLFLwriteSTLb are defined elsewhere in the SolidGeometry library and perform as expected.

Conclusion

The appsavegcaSTL function is a straightforward utility for exporting the geometry of the current MATLAB figure to an STL file. It relies on other functions within the SolidGeometry library to extract and write the necessary data.
