WebVectors are one of the main building blocks of 3D representation and drawing. They consist of three finite floating-point coordinates, traditionally called x, y, and z. The QVector3D class can also be used to represent vertices in 3D space. We therefore do not need to provide a separate vertex class. See also QVector2D, QVector4D, and QQuaternion.
