Detailed Description
By default, OpenGL supports up to 8 additional clipping planes. Qt3DCore::QClipPlane allows to enable one of these additional planes. These planes can then be manipulated in the shaders using gl_ClipDistance[i] where i varies between 0 and 7. The underlying implementation may support more than 8 clip planes, but it is not guaranteed.
Property Documentation
distance : float
Holds the distance of the plane from the world origin.
Access functions:
| float | distance() const |

Notifier signal:
| void | distanceChanged(float distance) |
normal : QVector3D
Holds the normal of the plane.
Access functions:
