However, be careful, 3D rotations can be counterintuitive in some ways (see box on right of page). One downside of using axis angle to represent 3D rotations is that we can't directly combine two rotations to give an equivalent total rotation, to do that we need to use matrices or quaternions, quaternions are related to axis angle so its not.

The other downside is that there are two singularities at Any 3D rotation can be represented in this way, in other words, given a solid object with orientation 1 and the same object with a different orientation 2. Then we can always find an axis and angle which will rotate from orientation 1 to orientation 2. Which direction of rotation is positive? On this site, we will use the right hand rule. Axis-Angle is probably one of the most easily understood methods for us to specify 3D rotations. The AffineTransform class represents a 2D affine transform that performs a linear mapping from 2D coordinates to other 2D coordinates that preserves the "straightness" and "parallelness" of lines. Affine transformations can be constructed using sequences of translations, scales, flips, rotations, and shears.

Axis and Angle is one possible way to represent the rotation of a solid 3D object. Other representations are: Description, rotation can be represented by a unit vector and an angle of revolution about that vector. Such a coordinate transformation can be represented by a 3 row by 3 column matrix with an implied last row of A tight profile of your resume should discuss what you are and just how your abilities and experience best affect the task you are looking at.
