Algorithm (Workflow)
This function, SGselectGroupofBBvol, is designed to process a solid geometry object and return the largest solid based on the volume of its bounding box. It also sorts all solids by their bounding box volumes.
Input Parameters
- SGorg: The original solid geometry object that is to be analyzed.
- gtyp: An optional parameter that specifies the group method for analyzing penetration. If not provided, it defaults to 'solid'.
Output Results
- SGN: The largest solid based on the bounding box volume.
- SGall: All solids sorted by the volume of their bounding boxes.
- vol: The volume of the bounding boxes.
- bb: The bounding box of the solids.
Algorithm Steps
- Retrieve the group type parameter using
getfuncparams, defaulting to 'solid' if not specified.
- Analyze the group parts of the original solid using
SGanalyzeGroupParts with the specified group type.
- Ensure the result is in cell format. If not, convert it to a cell array.
- Calculate the bounding box of the solids using
BBofSG.
- Determine the volume of each bounding box using
volofBB.
- Sort the volumes in descending order and rearrange the solids accordingly.
- Select the largest solid (first in the sorted list) and create a copy of it using
SGTcopy.
- If no output arguments are specified, visualize the original and largest solid using
SGfigure, SGplotalpha, and other plotting functions.
