I am still confused by model-view transformation.

Is the eye-coordinate space a Euclidian space? In other words, does the eye-coordinate space have orthogonal basis with (1,0,0), (0,1,0), and (0,0,1)? Or basis are distorted when perpespective view is used? The reason why I am asking is sometimes it is hard to track relationship among positions of models after rotate and transform.

To make question clear, let's say, after I changed to model-viw mode, I used only rotation and transform. Then, is the model-view matrix exactly same as muliple of the rotation matrix and the transform matrix?

Thank you for any help.
