Fit Bounding Box ================ Compute the smallest outer, or largest inner, bounding box of 3D data. Input ----- A single 3D volume, a mesh, or a point cloud. Output ------ Either the transformation of the input data is updated, or a resampled output volume is created. Description ----------- For smallest outer bounding box mode, rotation parameters are optimized in order to yield the smallest size of a 3D-rectangular bounding box. In largest inner mode, a full 6D pose is estimated.
