Hi Subbu,

It is possible to get the texture and surface normal information by shooting an intersect line from a cursor's 2D location on the window into the world.

But there are also some restrictions for getting the texture information, this method only work when the model's texture is applied in Vizard or a VRML file.

Here is the manual page which describe the method for your information.
http://docs.worldviz.com/vizard/Pick...the_screen.htm

And a simple sample code which I altered from the code shown in the above page.

Best.
Kevin
