This class was introduced in Qt 5.5.

Properties

Public Functions

float distance() const
QVector3D normal() const
int planeIndex() const

Public Slots

void setDistance(float)
void setNormal(QVector3D)
void setPlaneIndex(int)

Signals

void distanceChanged(float distance)
void normalChanged(QVector3D normal)
void planeIndexChanged(int planeIndex)

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)
