That is true, but it's safe to say that the number of people who do understand matrices is far greater than the number of people who understand quaternions. It's also worth pointing out that game engines and graphics APIs all deal in matrices, but don't all deal in quaternions. Mats can do what quats can do, but it's not true the other way around, quats cannot do everything matrices can do. Quats don't help with perspective, non-uniform scaling, or shear, just to name a few.
- user-the-name 5y agoI don't think the "far" part is safe to say, not in this day and age. Also, it is not really interesting what matrices or quaternions "can do". What is interesting is what we can do with them. And quaternions make a lot of things possible that are intractable or at least a huge pain with matrices.
