View Full Version : "Walking" with gluLookAt()

04-20-2006, 12:22 AM
I am building a 3D engine for a project and am trying to make it possible to walk through my 3D world as follows:

Up and Down arrow: Walk forward / backword
Left and Right arrow look to the left / right

When you press the forward arrow key i want to beable to walk in my line of sight.

I currently am using gluLookAt() to simply move forward and backwords (only in a staight line) I am having trouble implementing the rotation (changing of where im looking) correctly, does anyone have example sorce code or the algorithim for determining a new "look at point" ?
