fast::DataBoundingBox class
#include <FAST/Data/DataBoundingBox.hpp>

Defines the extent of a spatial data object.

Contents

This 3D BoundingBox class is used to define the extent of a data object, which is used when rendering to determine placement of the view camera

Constructors, destructors, conversion operators

DataBoundingBox(Vector3f pos, Vector3f size)
Create a bounding box from an offset pos and size.
DataBoundingBox(Vector3f size)
Create bounding box from a size vector, assuming data starts at origo.
DataBoundingBox(const std::vector<Vector3f>& coordinates)
Create bounding box from a set of coordinates.
DataBoundingBox(MatrixXf corners)
Create bounding box from a 8x3 matrix of corner coordinates.
DataBoundingBox()
Create an uninitialized bounding box.

Public functions
