As far as I know, it is not possible with the combination of these two tools. 
You can surely keep track of the coordinates on igraph's side (either using an 
igraph_matrix_t, or a regular two-dimensional C array) -- the problem is on 
Ubigraph's side because it does not allow you to specify the exact coordinates 
of a vertex (as far as I know).

A possible alternative is to use igraph's R interface from the R language as 
Gabor mentioned, because the R bindings contain a 3D visualization engine that 
you could use.
