Member Function Documentation

__hostdev__ bool init ( const RayT &  indexRay)
inline

Initialize the TreeMarcher with an index-space ray.

__hostdev__ const RayT& ray ( ) const
inline
__hostdev__ RayT& ray ( )
inline
__hostdev__ bool step ( const NodeT **  node,
float &  t0,
float &  t1 
)
inline

step the ray through the tree. If the ray hits a node then populate t0 & t1, and the node.

Returns
true when a node of type NodeT is intersected, false otherwise.
