QSphereGeometry Class

class Qt3DExtras::QSphereGeometry

The QSphereGeometry class allows creation of a sphere in 3D space. * * * * * The QSphereGeometry class is most commonly used internally by the QSphereMesh * but can also be used in custom Qt3DRender::QGeometryRenderer subclasses. More...

Notifier signal:

void generateTangentsChanged(bool generateTangents)

[read-only] indexAttribute : Qt3DCore::QAttribute* const

Holds the geometry index attribute.

Access functions:

Qt3DCore::QAttribute * indexAttribute() const

[read-only] normalAttribute : Qt3DCore::QAttribute* const

Holds the geometry normal attribute.

Access functions:

Qt3DCore::QAttribute * normalAttribute() const

[read-only] positionAttribute : Qt3DCore::QAttribute* const

Holds the geometry position attribute.

Access functions:

Qt3DCore::QAttribute * positionAttribute() const

radius : float

Holds the radius of the sphere.

Access functions:

float radius() const
void setRadius(float radius)

Notifier signal:

void radiusChanged(float radius)

rings : int

Holds the number of rings in the sphere.

Access functions:

int rings() const
void setRings(int rings)

Notifier signal:

void ringsChanged(int rings)

slices : int

Holds the number of slices in the sphere.

Access functions:

int slices() const
void setSlices(int slices)

Notifier signal:

void slicesChanged(int slices)

[read-only] tangentAttribute : Qt3DCore::QAttribute* const

Holds the geometry tangent attribute.

Access functions:

Qt3DCore::QAttribute * tangentAttribute() const

[read-only] texCoordAttribute : Qt3DCore::QAttribute* const

Holds the geometry texture coordinate attribute.

Access functions:

Qt3DCore::QAttribute * texCoordAttribute() const
