Detailed Description

This class handles spatial domains, i.e. oriented boxes that are represented through a spatial transform and the vector containing the half sizes of the box.

Short name: SBSpatialDomain

Constructor & Destructor Documentation

SBDTypeSpatialDomain()

SBDTypeSpatialDomain::SBDTypeSpatialDomain

(

const SBVector< SBPosition3 > &

positionVector

)

This constructor constructs a domain aligned with the principal axes of the positions contained in positionVector. The principal axes are the eigenvectors of the covariance matrix of the positions. The domain axes are sorted: the first axis corresponds to the longest domain dimension, while the third axis corresponds to the smallest domain dimension.
