* height value at each grid point. Note that the height values are not copied into the shape
* but are shared instead. The height values can be of type integer, float or double.
* When creating a HeightFieldShape, you need to specify the minimum and maximum height value of

* that for instance, if the minimum height value is -200 and the maximum value is 400, the final
* minimum height of the field in the simulation will be -300 and the maximum height will be 300.
