A QLogicalVertex simply references through to the data - in a QGeometryData for a particular vertex, providing accessors to fetch - position, texture coordinates, and other values. - - Create a QLogicalVertex referring to a particular QGeometryData instance: - \code - QGeometryData data; - data.appendVertex(QVector3D(1, 2, 3)); - - // construct a QLogicalVertex referring to the first vertex in data - // the QGeometryData is implicitly shared with lv - QLogicalVertex lv(data, 0); - // lv.vertex() == QVector3D(1, 2, 3) - \endcode - This is inexpensive and no new storage is allocated for the actual data, - just the reference and index. - - With logical vertices instances referencing large QGeometryData instances, - avoid modifying the instance: - \code - // careful - assigning to a QLogicalVertex which refers to an external - // QGeometryData will result in a possibly expensive copy-on-write - lv.setVertex(3, 2, 1); - \endcode - - Create a QLogicalVertex with its own QGeometryData internally: - \code - QLogicalVertex lv; - // no copy on write here - internal QGeometryData is not shared - lv.setVertex(1, 2, 3); - \endcode - - Assign an instance of QLogicalVertex: - \code - QLogicalVertex lv2; - lv2 = data.logicalVertexAt(0); - \endcode - Although lv2 gets its own internal QGeometryData which is then immediately - thrown away by the assignment, because of lazy initialization in - QGeometryData the cost is negligible. - - Use the fields() and hasField() functions to determine if a particular - field is present in the vertex. Accessing non-existent data will cause - an assert in debug mode (from the underlying QArray), and give - undefined behaviour in release mode. - - \sa QGeometryData, QGLBuilder -*/ - -/*! - \fn QLogicalVertex::QLogicalVertex() - Constructs a new invalid QLogicalVertex which has no data. -*/ - -/*! - \fn QLogicalVertex::QLogicalVertex(QGeometryData data, int index) - Constructs a new QLogicalVertex referencing the \a data at \a index. - Note that if this QLogicalVertex is modified, by calling vertex() or - setNormal() for example, then a copy-on-write for \a data will be - triggered. -*/ - -/*! - \fn QLogicalVertex::QLogicalVertex(const QVector3D &a) - Constructs a new QLogicalVertex with a vertex set to \a a. -*/ - -/*! - \fn QLogicalVertex::QLogicalVertex(const QVector3D &a, const QVector3D &n); - Constructs a new QLogicalVertex with a vertex set to \a a, and normal set to \a n. -*/ - -/*! - \fn QLogicalVertex::QLogicalVertex(const QVector3D &a, const QVector3D &n, const QVector2D &t) - Constructs a new QLogicalVertex with its vertex value set to \a a, normal set - to \a n, and texture set to \a t.
