transform_bounds()

template<typename T, int D>

Bounds< VecBase< T, 3 > > blender::bounds::transform_bounds ( const MatBase< T, D, D > & matrix, const Bounds< VecBase< T, 3 > > & bounds )

inline

Transform a 3D bounding box.

Note: this necessarily grows the bounding box, to ensure that the transformed bounding box fully contains the original. Therefore, calling this iteratively to transform from space A to space B, and then from space B to space C, etc., will also iteratively grow the bounding box on each call. Try to avoid doing that, and instead first compose the transform matrices and then use that to transform the bounding box.
