Detailed Description

template<typename Item, typename NodeData>
class mitsuba::StaticOctree< Item, NodeData >

Generic single-reference static octree.

This class is currently used to implement BSSRDF evaluation with irradiance point clouds.

The Item template parameter must implement a function named getPosition() that returns a Point.

Constructor & Destructor Documentation

template<typename Item , typename NodeData >
mitsuba::StaticOctree< Item, NodeData >::StaticOctree ( const AABB &  aabb,
uint32_t  maxDepth = 24,
uint32_t  maxItems = 8 
)
inline

Create a new octree.

Parameters
maxDepthMaximum tree depth (24 by default)
maxItemsMaximum items per interior node (8 by default)

By default, the maximum tree depth is set to 16

template<typename Item , typename NodeData >
mitsuba::StaticOctree< Item, NodeData >::~StaticOctree ( )
inline

Release all memory.
