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
void setDistance(float)

Notifier signal:

void distanceChanged(float distance)

normal : QVector3D

Holds the normal of the plane.

Access functions:

QVector3D normal() const
void setNormal(QVector3D)

Notifier signal:

void normalChanged(QVector3D normal)

planeIndex : int

Holds the index of the plane.

Note: Usually between 0-7.

Access functions:

int planeIndex() const
void setPlaneIndex(int)

Notifier signal:

void planeIndexChanged(int planeIndex)
