Finema,

>> it is possible to map this texture on my own model and not just a sphere ? <<

If your model is a 4 sided patch it will map. See attached. seamless texture on revolved surface.
If your model was a poly-surface it may be possible, however ensure seam map seamlessly may
be difficult.

UPDATED: more complex texture mapped form posted here:
