Algorithm (Workflow)

This algorithm is designed to process STL files of human surface models. It involves several steps to manipulate and prepare the data for further use or analysis. Below is a detailed explanation of the workflow and the functions used.

Input Parameters

STL File Path: The path to the STL file that contains the 3D model data.
ADAM_C.mat and ADAM_A.mat: Preloaded MAT files containing 3D model data.

Algorithm Steps

1. Load STL Data

The algorithm begins by loading STL data using the SGreadSTL function or by loading pre-saved MAT files using loadweb. This data is stored in variable C for the first model and A for the second model.

2. Fit Model to Bounding Box

The SGshrinktofit function is used to scale the model so that it fits within a specified bounding box. The result is stored back in the variable C or A.

3. Separate Model Components

The SGseparate function is applied to the model to separate its components into distinct parts.

4. Extract Surfaces

The SGsurfaces function extracts the surfaces of the model, storing the result in a cell array Ccell or AC.

5. Arrange and Write STL Files

The SGarrangeSG function arranges the separated components, and SGwriteSeparatedSTL writes these components to separate STL files. The files are named based on the intended use, such as 'Adams for FORM3'.

6. Box Packing

The SGboxpacking function is used to optimize the arrangement of components for packing. The result is stored in SGeos, and the packed model is written to an STL file using SGwriteSTL.

7. Reduce Model Complexity

The SGreduceVLFL function reduces the complexity of the model A to a specified number of vertices (e.g., 30,000).

8. Check Model with MeshLab

The SGcheckmeshlab function is used to verify the model's integrity and compatibility with MeshLab.

9. Plot Model

The SGplotalpha function is used to plot a specific component of the model with transparency settings.

10. Finalize and Close

All figures are closed, and the VLFLlicense function is called to display licensing information.
