Algorithm (Workflow)
This function, SGfittingsample, is designed to create a solid geometry for fitting experiments. It is part of the SolidGeometry library and was introduced in version 4.9. The function takes a single input parameter and returns a solid geometry object.
Input Parameters
- d: A vector containing a distance and a series of radii. The first element is the distance, and the subsequent elements are radii.
Output Results
- SG: The resulting solid geometry object.
Algorithm Steps
- The function begins by creating a base solid geometry using the SGsubtract function. It subtracts a union of surfaces from a box.
- The input parameter 'd' is processed using the getfuncparams function, which extracts the first element as the distance and the rest as radii.
- The maximum radius is determined using the max function.
- A profile line (PL) is created using the PLshaft function, which takes the radii and distance as inputs.
- The profile line is then rotated to create a solid geometry using the SGofCPLrot function.
- The height of the solid is calculated based on the number of elements in 'd'.
- A circular profile is created using the PLcircle function, which is then extruded along the z-axis using the SGofCPLz function.
- The solid geometry is refined by subtracting the extruded circle from the rotated profile using the SGsubtract function.
- Surface edge points are removed using the SGremsurfedgepoints function to clean up the geometry.
- Transformations are applied to the solid geometry using the SGTset function to set the front and back transformations.
- If no output is requested, the function plots the solid geometry using SGfigure and SGTplotalpha functions.
