Is there a common word that encompasses handling of position, rotation, and scale together?

Question

I'm looking for a name for my class that manipulates 4x4 matrices that handle position, rotation, and scale. Is there a common word that encompasses all three?

(I'm splitting the matrix math into its own file/class.)

Answer 1

transform, or transformation

Answer 2

If you add shear to your list (although rarely used in games), it is generally known in mathematics as an affine transformation.

The general term 'transformation' has been mentioned already, is a usually considered a superset and includes projection transformations as well (which are not affine).

Answer 3

I've seen PRS used (position, rotation, scale), but "transformation matrix" is a pretty informative name, and also covers other kinds of transformations (skewing etc).

Answer 4

I've seen several engines shorten the term to Xform as well.

Answer 5

Some variant of Transform or Transformation would work.
