0 pads, these are rotation matrices, you gotta fix theta and multiply it with an initial matrix that represents displacement, the result is a new reference point that you can use as the next joint of, for example, a robotic arm or video motion frame

Each column is the coordinates of the rotations of (1,0,0), (0,1,0), (0,0,1) respectively. In R_X for example, the first column is on the x-axis and so it doesn't move at all (and (1,0,0) has two zeroes), the other two columns remain on the Y-Z axis and so the x-coordinate remains 0

why would initial matrix represent displacement

is this a joke

....is that not the same as writing y = 1++ or y = y+1

Yes. Some mathematicians also write "z += x-%y2"

% is used in math to indicate rotation around a 3D axis, it's a visual pun of sorts

why would it not be, your displacement is a translation relative to a "reference" origin, which is a previous frame at this point where no rotation has occurred yet.

CUZ THERE IS NO DISPLACEMENT IN a 3D Camera space. oh wait there is.

just draw a vector in a cartesian CS and look how the components change when expressed in a rotated CS. do that for rotations around x, y and z and you get the matrices in the OP

here my friend, i only did a 2D-vector for rotations around the z-axis as it is easier to visualize. the z-component obviously doesnt change for rotations a round z and doesnt play a role in the component for x and y which explains the 0s and 1 ib the 3x3 matrix
