Algorithm (Workflow)
The function BBconcat is designed to concatenate two bounding boxes, BBA and BBB, and produce a new bounding box BBC that encompasses both input boxes.
Input Parameters
- BBA: A bounding box or a solid object. If it is a solid, it is converted to a bounding box using the function
BBofSG.
- BBB: Another bounding box or solid object. Similarly, if it is a solid, it is converted to a bounding box using
BBofSG.
Output
- BBC: The resulting bounding box, defined by the minimum and maximum extents in the x, y, and z dimensions: [xmin, xmax, ymin, ymax, zmin, zmax].
Algorithm Steps
- Store the original inputs
BBA and BBB in BBAorg and BBBorg for potential plotting later.
- Check if
BBA is a solid object using isSG. If true, convert it to a bounding box using BBofSG.
- Check if
BBB is a solid object using isSG. If true, convert it to a bounding box using BBofSG.
- Initialize
BBC with the values of BBB.
- Calculate the minimum values for
xmin, ymin, and zmin by comparing the corresponding values of BBA and BBB.
- Calculate the maximum values for
xmax, ymax, and zmax by comparing the corresponding values of BBA and BBB.
- If no output is requested (i.e.,
nargout==0), plot the resulting bounding box and the original inputs using SGfigure and SGplotalpha functions.
