Syntax
template<typename COLL_DATA_PROVIDER, typename KDOP_IDX_TYPE>
struct TkDOPLineCollisionCheck :
public TkDOPCollisionCheck< COLL_DATA_PROVIDER, KDOP_IDX_TYPE >,
public TkDOPCollisionCheck< COLL_DATA_PROVIDER, KDOP_IDX_TYPE >
Remarks
This struct holds the information used to do a line check against the kDOP tree. The collision provider gives access to various matrices, vertex data etc. without having to use virtual functions.

 |
FVector4 | LocalDir | |
 |
FVector4 | LocalEnd | |
 |
FVector4 | LocalHitNormal | Normal in local space which gets transformed to world at the very end. |
 |
