Hi deepak,
It should be simple in normal cases.
Lighting up the scene should solve this.

thank u Mr.Sivan, i found that if we light the text with very low angle, we can feel the depth as the shadows fall inside the bevelled areas, and also we can solve the problem by adding more depth to extrusion.
