need some help with COSM library, if some one knows about ( 

http://www.allosphere.ucsb.edu/cosm/reference.html#cosmnav

Tried to look for cosm author's email, but couldn't find it anywhere, neither on his website.

I would like to know what type of coordinates should be given to the object

for specifying a 3D location of the rendered graphic object.

On the reference it mentions to use X Y Z world coordinates.

Yet what is the exact value range of these world coordinates?

I did some tests, but cannot figure this out, resulting data is confusing.

many thanks in advance

So the range is defined in the cosm.world object using @size 64 where 64 is the radius of the world in OpenGL units. So if you have a world of size 16, the position goes from -16. to 16. However, what leaves one side of the world returns on the other, so if you have a radius of 8 and a position of 10 it'll appear on the wrong side of the room than you might expect.

You can then use cosm.gl.bounds to paint the boundaries of the room created by cosm.world.
