As the semester is coming to an end I would like to try to accomplish getting the world builder scene to rotate. From my last video, I really like how the scene can be adjusted by using the leap motion to draw the scene up, down, into, and out of the screen.

Next I would like to be able to rotate the scene along the x axis. So when the hand is closed we would save the position of the hand in the (x,y,z) plane and then rotate about the x axis so that you could see the backside of the figure that you are drawing.

I am hoping to do this action is one finger. When the rotation would be based up the change of x and the finger moves left to right. To accomplish this I will be using the GLrotatef(angle, x,y,z) function where x = change of x and the y and z are both constant. I am having trouble finding a way to calculate the angle for this function. I believe I will need to find the angle between the start point when he hand grabs the world and the ending point when the hand releases the world.

I will be making another video to demonstrate this effect tomorrow.
