Which bounding box algorithm?
Hi. I am trying to find some information about an algorithm that can generate the following type of bounding box as indicated by the green box around the red polygon "B". I already have an algorithm that generates the bounding box around polygon "A", but I have no idea what the name of an algorithm to produce the kind of bounding around polygon "B" would be called. Some help please. Thanks.
They're called 'Oriented Bounding Boxes' I haven't worked with them so I couldn't tell you how to build one.
Well I can search for information on how to implement this, if that's correct name of this kind of algorithm. I thought it was something like minimum perimeter bounding box, or something. Thanks.
Quote:Original post by kelaklubYes, it looks like you're looking for the oriented bounding box with the minimum area/perimiter. There are at least a couple of algorithms that are commonly used; terms to google for to learn more about these might include 'rotating calipers', 'OBB eigenvectors', and 'OBB covariance'.

Here is a google hit that looks promising. I can't vouch for its accuracy, but otherwise it looks like what you're looking for.
"Object-Oriented Bounding Box" (OOBB) might bring up more specific relevant information ("A" is bounded by an "Axis-Aligned Bounding Box" (AABB))
