Detailed Description

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.

Property Documentation

generateTangents : bool

Holds the value of the automatic tangent vectors generation flag. Tangent vectors are orthogonal to normal vectors.

Access functions:

bool generateTangents() const
void setGenerateTangents(bool gen)

Notifier signal:

void generateTangentsChanged(bool generateTangents)

indexAttribute : Qt3DRender::QAttribute * const

Holds the geometry index attribute.

Access functions:

Qt3DRender::QAttribute *indexAttribute() const

normalAttribute : Qt3DRender::QAttribute * const

Holds the geometry normal attribute.

Access functions:

Qt3DRender::QAttribute *normalAttribute() const

positionAttribute : Qt3DRender::QAttribute * const

Holds the geometry position attribute.

Access functions:

Qt3DRender::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)

tangentAttribute : Qt3DRender::QAttribute * const

Holds the geometry tangent attribute.

Access functions:

Qt3DRender::QAttribute *tangentAttribute() const

texCoordAttribute : Qt3DRender::QAttribute * const

Holds the geometry texture coordinate attribute.

Access functions:

Qt3DRender::QAttribute *texCoordAttribute() const

Member Function Documentation

QSphereGeometry::QSphereGeometry(QNode *parent = nullptr)

Constructs a new QSphereGeometry with parent.

void QSphereGeometry::updateIndices()

Updates indices based on rings and slices properties.

void QSphereGeometry::updateVertices()

Updates vertices based on rings, slices, and radius properties
