Member Function Documentation

template<typename GRID> bool CEntityRayPicker< GRID >::intersects (  const CEntity &    e, const GRID::TSector &    sector )  [inline, static]

Checks entity-ray intersection. Checks intersection of an entity with a ray that is in a given sector. If a sector does not contain a ray, no intersection is reported. Parameters: e  Entity. sector  Sector. Returns : True if intersection occured, false otherwise.

template<typename GRID> void CEntityRayPicker< GRID >::putRay (  GRID &    grid, const D3DXVECTOR3 &    origin, const D3DXVECTOR3 &    dir )  [inline, static]

Puts ray into grid. For all sectors that are touched by a ray, puts the ray into the sector. Does not modify untouched sectors. Parameters: grid  The grid. origin  Origin of the ray. dir  Direction of the ray (can be not unit vector).
