* OGC 06-103r4 6.1.10 specification: |

|
|
|
* A simple Surface may consists of a single “patch” that is associated with one “exterior boundary” and 0 or more |
|
11
|
|
|
* “interior” boundaries. A single such Surface patch in 3-dimensional space is isometric to planar Surfaces, by a |
|
12
|
|
|
* simple affine rotation matrix that rotates the patch onto the plane z = 0. If the patch is not vertical, the |
|
13
|
|
|
* projection onto the same plane is an isomorphism, and can be represented as a linear transformation, i.e. an affine. |
