3D data visualization

[kamaraju kusumanchi <raju.mailinglists@gmail.com>]

Just wondering what you would recommend for 3-D data visualization? 
Currently our group uses Tecplot. But it is commercial and would like to 
have a free alternative. Gnuplot though excellent for 2D, is not very 
good for 3-D. For example gnuplot cannot plot stream lines, velocity 
vectors etc., Any other suggestions?
