Template plane class with some intersection testing methods. More...
#include <plane3d.h>
Template plane class with some intersection testing methods.
It has to be ensured, that the normal is always normalized. The constructors and setters of this class will not ensure this automatically. So any normal passed in has to be normalized in advance. No change to the normal will be made by any of the class methods.

| bool irr::core::plane3d< T >::isFrontFacing | ( | const vector3d< T > & | lookDirection | ) | const [inline] |
Test if the triangle would be front or backfacing from any point.
Thus, this method assumes a camera position from which the triangle is definitely visible when looking into the given direction. Note that this only works if the normal is Normalized. Do not use this method with points as it will give wrong results!
