Property Documentation

height : float

Holds the plane height.

Access functions:

float height() const
void setHeight(float height)

Notifier signal:

void heightChanged(float height)

indexAttribute : Qt3DRender::QAttribute* const

Holds the geometry position attribute.

Access functions:

Qt3DRender::QAttribute *positionAttribute() const

resolution : QSize

Holds the plane resolution.

Access functions:

QSize resolution() const
void setResolution(const QSize &resolution)

Notifier signal:
