详细描述
The QSurfaceDataItem class provides a container for resolved data to be added to surface graphs.
A surface data item holds the data for a single vertex in a surface graph. Surface data proxies parse data into QSurfaceDataItem instances for visualization.
参见 QSurfaceDataProxy and Qt Data Visualization C++ Classes.
