Notes on Linear Transformations

It's unfortunate that you would mention "Move the object to the desired location", then proceed to ignore it entirely.

Of course that is because translation is not a linear transformation, but you then proceed to also not demonstrate the very common trick used to enable it (so common in fact that GPUs are designed around it).

In case it's not clear, you are (I assume) linking to an explanation of the "common trick" mentioned by stefan_ (https://news.ycombinator.com/item?id=22412340). Specifically, you are linking to a question that necessitates this trick; one somewhat terse explanation of the trick is the answer https://math.stackexchange.com/a/251566 .

You are correct, thanks.

Hey! Thanks for the feedback, you are already the second person to share this with me, so clearly I messed up!

My intention was to do a follow up post with affine transformations, but I failed to communicate that.
