This script exports meshes to Nendo file format.
Nendo is (was) a commercial polygon modeler that has about half of the
features found in Wings. The .ndo file format is a simple, uncompressed,
memory dump of structures that represent the mesh objects, uv coords,
and image textures.
Usage:<br>
Select meshes to be exported and run this script from "File->Export" menu.
Supported:<br>
1. Exports meshes only. Hint: use ALT-C to convert non-mesh objects,
and CTRL-ALT-A if you have "dupliverts" objects.<br>
2. Exports Vertex Colors & Radiosity Solutions.
Missing:<br>
Materials and UV Coordinates info will be ignored.
Known issues:<br>
Exports only well-behaved and topologically correct meshes (i.e,
closed meshes, manifolds, meshes imported from wings, etc). The mesh
cannot have duplicate vertices, missing faces (holes), open edges, etc.<br>
PowerUser Hint: In editmode, if CTRL-ALT-SHIFT-M results in a selection,
then your mesh is not a manifold and most likely will not export.
Notes:<br>
Blender & Wings can read/write ndo files with a maximum of 65,535 edges.
Nendo can read/write ndo files with a maximum of 32,767 edges.<br>
If you have a very large mesh that you want to import into nendo, modify
the 'write_edge_table' function to use a signed integer (i.e., ">h") for the 'len(edge_table)'
field.
