A solid understand of the basics of linear algebra at least, like an introductory high school or university course.

You need to know at least complex numbers, vectors, matrices, and their operations.

and what about kinematics/inverse kinematics?
what are their requirements? the same? since they're inside quaterions and rotation matrices.

A solid understanding of kinematics :P
It comes with every introductory physics course and it's pretty simple.

i'm currently at my second year of high school.
do you think i can try to learn it?
i have already advanced math and physics knowing for my age.

5 :)
Where should i start learning quaternions? linear algebra?

First, 2 + 2 is 4. And quaternions are very complicated, expect a lot of work to learn them.

I'm sure quaternions are fairly easy. You're only adding a fourth axis of rotation, right? Diagrams help a lot with this sort of thing.
But to be honest, I really only use the matrix since quaternions I never bothered with.

you can really work with inverse kinematics without using quaternions?

What's wrong with a college student playing Roblox?

And no, you don't need quaternions for inverse kinematics.

Inverse kinematics are simple force vectors with trigonometry. You need those two, which I found are in mid years of HS or HS physics.

I could be in college playing Roblox, but I just forum and sometimes make models which are basically libraries, but some of the stuff I make can save you a HEADACHE... such as sounds playing in regions...

So... how could i write inverse kinematics? Because, i think i need some knowings of kinematics first...

hah.

ye i found out its not that difficult

but my method is just super crappy and its kinda difficult to make a c00l one

i know that inverse kinematics hasn't an analytic resolution.
that's why they use quaternions in IKs?
