Detailed Description

QHeightMapSurfaceDataProxy takes care of surface related height map data handling. It provides a way to give a height map to be visualized as a surface plot.

Since height maps do not contain values for X or Z axes, those values need to be given separately using minXValue , maxXValue , minZValue , and maxZValue properties. X-value corresponds to image horizontal direction and Z-value to the vertical. Setting any of these properties triggers asynchronous re-resolving of any existing height map.
