Aditi,
there is already very much done here. Anurag did most of the work in
2012's Summer of Code (http://brlcad.org/wiki/User:Anuragmurty). You
should consult the references Sean gave you, test the voxelize command
in mged and the g-voxel program. In your proposal you should point
out then what you want to do on top of this.
Regards,
Daniel
