Gained a better understanding of the glFrustumf today. Had some discussions with Kevin and some colleagues that he brought in. They were really helpful and seriously intelligent.
We realized that the normalized device coordinates always ranges from -1.0 to 1.0 on both the x and y axes. Hence, during the translation of window coordinates to normalized device coordinates, I have to scale the values down. With this, I was able to translate the positions properly.
The next thing that I am trying to solve is the problem with perspective. If the zNear and zFar values are not in the positive range, we would not be able to see any perspective. If we have perspective, the translation of coordinates would not be displayed in the way that we want it to be. Hence, I would have to spend more time trying to understand how this works on Monday.
Spent some time looking into swipe gestures as well. Earlier this week, I was only able to do swiping in one direction, left to right. I found out that we are actually able to swipe up, down, left and right. Now the next thing that I want to look into is if swipe gestures would work when I have pan gestures added to the view. These gestures does not seem to work well on the simulator. I might probably request to try this out on a real device to see if it's a limitation on the simulator.
