====== Notes on WKT Support ======

Using ''addWKT()'' and ''addWKTToWKT()'' functions custom geometries can be added as a layer.  

These WKT primitives are supported : 
  * POINT
  * LINESTRING
  * POLYGON
  * TRIANGLE
  * MULTIPOINT
  * MULTILINESTRING
  * MULTIPOLYGON
  * POLYHEDRALSURFACE
  * TIN
  * GEOMETRYCOLLECTION

Please specify geometries with a Z component for 3D data.  Data without a Z component will be projected on an imaginary ground plane, calculated using the current photo position and camera height.

Some examples can be found here : http://en.wikipedia.org/wiki/Well-known_text

===== Caveats =====

For multipoint geometries, only the syntax where each point is enclosed by brackts is supported.

  * Supported : <code>MULTIPOINT ((10 40), (40 30), (20 20), (30 10))</code>
  * NOT Supported : <code>MULTIPOINT (10 40, 40 30, 20 20, 30 10)</code>
