Thank you very much for the reply Crossbones. I tried with changing the eye position calculated from rotation vector but don't understand why it is not working. I would like to use OpenGL. Could you provide any related examples? Also could be a more elaborate on how to change gluLookAt function?
Thanks again.

Hi jenny,

RE: " I saw Nate Robbin's tutorial but a confused how to make it work."

Thats not a good sign. You will be struggling with this until you do understand the fundamental concepts that Nate's samples are based on. Have you downloaded the examples and ran them?: Have you played around with the values in them to learn by doing and seeing the effects of changing parameters? You cannot get around doing something like this in order to grasp the fundamental knowledge you need to get to a solution. There are no short cuts. It is a matter of finding material suitable to the way you learn.

So here are a few things to try:

Search on terms like "opengl camera". there is lots of info around: only you know what will suit you.

Start by reading this: http://www.glprogramming.com/red/chapter03.html. Or even scanning it for (more hands on) examples to here:

http://www.glprogramming.com/red/chapter03.html#name8. This stuff is an example of the easiest/simplest and well explained info you must grasp before you try to solve your problem (otherwise you will continually be asking people to hold your hand on every little step of your journey into 3d graphics likely making very little progress).

Let us know if this helps
