Member Function Documentation

init()

template<typename NodeT, typename RayT, typename AccT, typename CoordT = Coord>

__hostdev__ bool init ( const RayT & indexRay )

inline

Initialize the TreeMarcher with an index-space ray.

ray() [1/2]

template<typename NodeT, typename RayT, typename AccT, typename CoordT = Coord>

__hostdev__ RayT & ray ( )

inline

ray() [2/2]

template<typename NodeT, typename RayT, typename AccT, typename CoordT = Coord>

__hostdev__ const RayT & ray ( ) const

inline

step()

template<typename NodeT, typename RayT, typename AccT, typename CoordT = Coord>

__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.
