SGconvexHullXYZ

by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - SG/Solids
Introduced first in SolidGeometry 5.3, Creation date: 2023-02-21, Last change: 2025-09-15

creates a convex solid by the intersection of the three projections in X Y Z

Description

ATTENTION: Since 2 boolean operations are used in a sequence, there is a significant risc of non watertight models
Tim Lueth considers this function as unreliable but helpful
(First Version from 2019-07-17 named SGofSGhull)
SGofBB(SG) Creates the Bounding Box Solid in the world frame
SGBB Creates the Bounding Box Solid in the solids frame
SGconvexHull(SG) Create the Convex Hull in in the solids frame
SGconvexHullXYZ(SG) Create the projected Convex Hull in the world frame
