There seems to be a misconception that linear transformations have to look like lines.
- blattimwind 8y agoOne easy way to see that "linear" does not mean "line-like" is looking at matrix transforms: All matrix transforms are linear. And we can do a lot of stuff easily with those, like rotating, distorting, even perspective (with w-normalization).
- speedplane 8y agoAll matrix transforms are linear. And few people understand matrix transforms. The term itself "linear" transform stems more from the contrast to nonlinear equations, but it still "feels" like a bit of a misnomer. Perhaps it should be called "proportional" or "relatable" transform. Ehh, then again, it doesn't really matter, people who don't understand it still won't with a nomenclature change.
