My iPhone app rotates fine in the simulator but when I deploy it on a physical device, rotating is very very sensitive. How can I fix this issue and make sure the screen rotates only when a 90 degree angle is made?

I would recommend manually monitoring the accelerometer....
I assume you couldn't use the built-in autorotate callbacks for your requirements but have to build your own view rotation or alternate views that are controlled by readings from the accelerometer.

I have 12 views which I rotate almost similar to the icons in the home screen when going into homescreen-customization-mode by touching an icon for a few seconds.
I use a 3D transformation code to do the rotations. They have each a duration of just 0....

How big on screen are the images?
CALayer rotations are hardware.

I have a 3D point in cartesian coordinates, how can I get the euler rotation angles of it based on its distance from 0,0,0?

Be aware that Euler angles can be ambiguous: Rich's answer assumes the rotations are applied to Z.

I'm implementing a simple camera system in OpenGL. I set up gluPerspective under the projection matrix and then use gluLookAt on the ModelView matrix. After this I have my main render loop which checks for keyboard events and, if any of the arrow keys...

Swap your rotate and translate calls around :)
Since they post-multiply the matrix stack the last the be called is the 'first' to be applied conceptually, if you care about that sort of thing.

Hopefully easy answer, but I cannot get it.
I have a 3D render engine I have written.
I have the camera position, the lookat position and the up vector.
I want to be able to "tilt" the camera left, right, up and down. Like a camera on a fixed tripod that...

To get the horizontal plane, you can get one vector as the cross product of the up... .
It may not be mathematically optimal, but you could de-compose the camera to look-at vector into three vectors - two that define the horizontal plane, and the up vector .

I'm considering away rotations for "audition" rotations in the fall. I realize that these rotations can be double edged - they help you if you do well but hurt if perceived performance is poor. On the other hand applying to residency simply with a decent...

Fantasy Dinning Rotations
I know this has been posted on here somewhere but I can't find it.
Can someone please help me out and tell me what are the standard rotations for the MDRs on the Fantasy?
for example REARREA

Do not miss either Animator's night! As two adults on the Western, our rotation was ERARREA.
This put us in Royal for Formal night, although that wasn't planned .
