Notes on Linear Transformations
- stefan_ 7y agoIt'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).

- JadeNB 7y agoIn 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 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 https://math.stackexchange.com/a/251566 .
- pacala 7y agoYou are correct, thanks.
- roperzh 7y agoHey! 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.
