I didn't find any documentation about the (12) values describing a polyhedron. Would somebody please enlighten me?

No clue why I didn't find the answer myself that other night... guess I had too much wine :x

Taken from trigger.cpp:

From what I remember, for all practical purposes, even if you do a skewed quadrilateral (non-rectilinear), most of the collision calcs operate on a bounding box generated from the min and max of the quadrilateral so there isn't much point in defining anything but a box.

I tried to use polyhedrons for (size) calculated triggers around doors. Unfortunately the idea failed due to other reasons.

I found that it's much better to work with triggers by changing scale of trigger object instead of playing with polyhedron values.
While in world editor (F11 -> F3), press Ctrl+Alt and move the mouse of the side of trigger - click and drag. Very easy way of making your trigger the size you want.
