Making export pluging for Cinema4D. How uv define texture position in xml?

Hi, I'm coding a world xml export plugin for Cinema 4D. Just started with CS, and can't figure out how uv defines the texture position; in "Intro to Building Maps in XML" article, the faces in the cube are textured as

<p>
<v>1</v>
<v>2</v>
<v>3</v>
<v>0</v>
<material>defaultWall</material>
<texmap>
<uv idx="0" u="1" v="0"/>
<uv idx="1" u="1" v="1"/>
<uv idx="2" u="0" v="1"/>
</texmap>
</p>

There are three idx; I suppose they are ids for the uv coordinates. Could be rotation, scale and position, but I have played with the numbers and I can't figure out how they work. Somebody help, please?

Please don't export to thing mesh. Thing mesh is obsolete and will be gone in 1.4. Please use genmesh instead.

Greetings,

Ok. The export plugin is now made with genmesh. The mesh is ok, the uv must be corrected as they are not quite right, but it looks good.

 The first part of the plugin is finished; the mesh is correct and the UV's too. Right now it writes *all* points in each triangle of the object, so for a cube, for example, it writes 36 points, some of them redundant. I'm coding it to optimize the output so only unique points are exported (must be very easy, but it is turning to be a nightmare!). Suppose next step will be submeshes; where are they documented? Only found reference to them in http://cel.crystalspace3d.org/docs/online/manual/MeshObject-Genmesh.html but not a word about indexbuffers as suggested by bookeater2 in http://cel.crystalspace3d.org/docs/online/manual/MeshObject-Genmesh.html

 How indexbuffer (components, type, indices ... ) work?

 Thanks
