The first affine transform.
The second affine transform. This affine transform is concatenated to the first affine transform.
A new affine transformation matrix. That is, t’ = t1*t2.
Concatenation combines two affine transformation matrices by multiplying them together. You might perform several concatenations in order to create a single affine transform that contains the cumulative effects of several transformations.
Note that matrix operations are not commutative—the order in which you concatenate matrices is important. That is, the result of multiplying matrix
t1 by matrix
t2 does not necessarily equal the result of multiplying matrix
t2 by matrix
