Drawing a 'bounding box' can typically be done with the OpenCV vision software, which the RealSense SDK is fully compatible with. The SDK has a couple of example programs that use OpenCV to do this.

A simpler example of creating a bounding box with OpenCV can be found here:

If you wanted to draw a three-dimensional bounding box, that is a bit more complicated.
