◆ Intersection() [1/3]

std::pair<Bool_t, TGLLine3> Intersection ( const TGLPlane p1,
const TGLPlane p2 
)

Find 3D line interestion of this plane with 'other'.

Returns a std::pair

first (Bool_t) second (TGLLine3) kTRUE - planes intersect intersection line between planes kFALSE - no intersect (parallel) undefined

◆ Intersection() [2/3]

std::pair<Bool_t, TGLVertex3> Intersection ( const TGLPlane p1,
const TGLPlane p2,
const TGLPlane p3

Definition at line 531 of file TGLUtil.cxx.

◆ Intersection() [3/3]

std::pair<Bool_t, TGLVertex3> Intersection ( const TGLPlane plane,
const TGLLine3 line,
Bool_t  extend 
)

Find intersection of 3D space 'line' with this plane.

If 'extend' is kTRUE then line extents can be extended (infinite length) to find intersection. If 'extend' is kFALSE the fixed extents of line is respected.

The return a std::pair

  • first (Bool_t) second (TGLVertex3)
  • kTRUE - line/plane intersect intersection vertex on plane
  • kFALSE - no line/plane intersect undefined

If intersection is not found (first == kFALSE) & 'extend' was kTRUE (infinite line) this implies line and plane are parallel. If 'extend' was kFALSE, then either line parallel or insufficient length.
