Create a lookup table of the terrain's height.
| [in] | _subsampling | Multiplier used to increase the resolution. Ex: A subsampling of 2 in a terrain of 129x129 means that the height vector will be 257 * 257. |
| [in] | _vertSize | Number of points per row. |
| [in] | _size | Real dimmensions of the terrain. |
| [in] | _scale | Vector3 used to scale the height. |
| [in] | _flipY | If true, it inverts the order in which the vector is filled. |
| [out] | _heights | Vector containing the terrain heights. |
