Export questions

Hello,

I am currently working on writing a Collada Exporter for one of our software projects. We would like to export a very simple scene:

a cloud of points (static)
a camera (including camera parameters, animated)

Could someone point me to a very simple example file especially for the camera movement? What’s the correct way to define a “point” (a marker would suffice). I created nodes for every point, when imported into 3dsmax they show as bounding boxes.

Many thanks

Markus
