SGisIntersectingBB
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Geometric Queries
Introduced first in SolidGeometry 4.9, Creation date: 2020-01-16, Last change: 2025-09-14
returns all facets of a solid that are crossed/intersected by a bounding box
Description
The bounding box can also be a SGofBB Solid Geometry, and it is also possible to transfer the bounding box by a HT Frame like SGofBBui.

Syntax
[SGi,si,ci,SIL]=SGisIntersectingBB(SG,bb,[T])
Input Parameter
SG: | | Solid Geometry |
bb: | | bound bog or second solid |
T: | | Transformation matrix for bb |
Output Parameter
SGi: | | Solid that has faces that are crossed/intersected by the BB |
si: | | facets of SG (not SGi) that are crossed/intersected by BB |
ci: | | facets of SG (not SGi) that belong to the same surfaces of si |
SIL: | | Sort Selection and Index list used to create SGi using VLFLselect |
Examples
SG=SGofCPLcommand('c 4, h 10 m 4, dupg 3 3 1 20');
