3D Navigation with Camera settings
May 5th, 2006, 2:54am  
I've been using transforms (translate and rotateX/Y) for keyboard/mouse navigation of 3D scenes.  I'd want rotation, translation and zoom via mouse and keyboard.  Here is an example:
 http://www.backspaces.net/models/GraphViz/applet/

But I'm told its much better to do this via moving the camera.

Is there a demo of this sort of thing?  I'd want to change the scene center and camera x,y and z values which are in the camera(...) function.  But upX,Y,Z don't make sense to me.  And would I also need to use frustum(..) and perspective(..)?

Sorry for being such a newbie!  A search didn't clarify the details, alas.

I cant say if it is better or worse than they way you are doing it, but have you taken a peek at the OCD library?
