/** |
||||||
|
* Used for TerrainQuad to find neighbours that are not part of the |
||||||
|
* same quad tree. Normally TerrainQuads function in a quad tree and |
||||||
|
* use the neighbour methods getRightQuad, getLeftQuad etc. to update |
||||||
|
* LOD values of the terrain (and for some other routines). |
||||||
|
* |
||||||
|
* With this you can have a parent, control or spatial, that manages a group of |
||||||
|
* TerrainQuads by linking them together through these four methods. |
||||||
|
* |
||||||
|
* The general orientation of TerrainQuads and their sun-quads is as such: |
||||||
|
* |
||||||
|
* |
||||||
|
* +-- x+ ----> |
||||||
|
* | |
||||||
|
* | 1 | 3 (quadrants) |
||||||
|
* z+ --+-- |
||||||
|
* | 2 | 4 |
||||||
|
* | |
||||||
|
* \/ |
||||||
|
* |
||||||
|
* Your implementation will still have to manage getHeight, getNormal, and |
||||||
|
* most other Terrain.java interface methods; often by offsetting the XZ |
||||||
|
* coordinate parameters. |
