Farid,

	What are you exactly looking for :

1. Read some other file format VTK/ParaView does not support ?
or
2. Make ParaView link to OpenCascade to be able to access the structure ?

For #1, have a look at other readers in VTK, to help you start writting 
your own.

As for #2, have a look at the newly added abstraction layer in VTK:

http://www.vtk.org/doc/nightly/html/classvtkGenericAdaptorCell.html
http://www.vtk.org/doc/nightly/html/classvtkGenericDataSet.html

Those classes are empty nutshell you can plug to third party library 
(such as OpenCascade).

Ps: On a side note you can also have a look at my previous work to read 
IGES file using opencascade lib at :
