Algorithm (Workflow)
This function, CVLzofSGsliceauto, is designed to process a Solid Geometry (SG) object and return a Closed Vertex List (CVL) of all z values that have a significant distance between them. The function is part of the SG-Library and was introduced in SolidGeometry version 4.4.
Input Parameters
- SG: This is the Solid Geometry object that the function will process. It represents the 3D model or shape that is being analyzed.
- dz: This is an optional parameter that specifies the minimal change in the z-direction that is considered significant. If not provided, the default value is calculated as the bounding box size of the SG object divided by 50.
Output Results
- CVL: The function returns a Closed Vertex List, which is a list of all z values that have a significant distance between them, based on the provided or default
dz value.
Function Workflow
- The function begins by calling
CPLofSGsliceauto with the provided SG object and any additional arguments. This function processes the SG object to determine the slices based on the z values.
- The result from
CPLofSGsliceauto is a tuple, and the second element of this tuple is assigned to CVL.
- If no output is requested (i.e.,
nargout==0), the function proceeds to visualize the SG object and the resulting CVL:
- It calls
SGfigure to create a new figure window.
- It sets the view angle to (-30, 30) for better visualization.
- It plots the SG object using
SGplot and adjusts the lighting with setplotlight.
- Finally, it plots the CVL using
CVLplot with a specific style ('.-').
Example Usage
An example of how to use this function is provided in the comments:
SGreadSTL; A=ans; SGrotateservo(A); B=ans
CVLzofSGsliceauto(B);
This example reads an STL file, rotates the resulting SG object, and then calls CVLzofSGsliceauto to process it.
