Detailed Description

template<class T, class CellT = DefaultCell<T,8>>
class Geometry::HGrid< T, CellT >

Hierarchical voxel grid.

In many cases we wish to save on the storage requirements of volumes. A hierarchical voxel grid is a volume representation where the volume is divided into box shaped regions, and each region is represented only if it contains voxels. This class template is for such a grid.

Member Function Documentation

template<class T, class CellT = DefaultCell<T,8>>

const T& Geometry::HGrid< T, CellT >::operator[]

(

const CGLA::Vec3i &

p

)

const [inline]

Read only access to a voxel in the grid.

Reimplemented from Geometry::AncestorGrid< T, HGrid< T, CellT > >.

template<class T, class CellT = DefaultCell<T,8>>

void Geometry::HGrid< T, CellT >::store	(	const CGLA::Vec3i &	p,
		const T &	vox
	)		[inline]

Store a voxel vox at position p in grid. The Cell will automatically subdivide if it is not already subdivided.

Reimplemented from Geometry::AncestorGrid< T, HGrid< T, CellT > >.
