As in the lower dimension, there are three basic types of transformation: translation, scaling and rotation. We will represent transformations as square matrices (now they will be 4 脳 4). A general point in space relative to a fixed coordinate triad, the row vector ( x , y , z ), ...
The transformation is a 3-by-3 matrix. Unlike affine transformations, there are no restrictions on the last row of the transformation matrix. Use any composition of 2-D affine and projective transformation matrices to create aprojtform2dobject representing a general projective transformation. ...

A 3x3 matrix is used for transformations in a 2D x-y plane. Affine transformation matrices can be multiplied to form any number of linear transformations, such as rotation and skew (shear), followed by translation. An affine transformation matrix has its final column equal to (0, 0, 1), ...
3.2. Matrix Representation for Image Transformation If we subject a pixel to multiple transformations, the result of the previous transformation must serve as the input for the subsequent transformation: Concatenating multiple transformation matrices results in a combined transformation matrix, which we can...
