Hello everyone. The title says what I am looking for. I am just wanting confirmation on my understanding of the information that I have on the camera matrix. If any of my understanding is wrong I would greatly appreciate any corrections.
matrix:
x1 y1 z1 w1
x2 y2 z2 w2
x3 y3 z3 w3
x4 y4 z4 w4
Ok, now this is how I understand the above camera matrix.
w1 w2 w3 w4 = camera translation in world space
x1 y1 z1 w1 = X axis orientation of the camera
(strafe? vector)
x2 y2 z2 w2 = Y axis orientation of the camera (or up vector)
x3 y3 z3 w3 = Z axis orientation of the camera
(or view/look at vector)
x1 y2 z3 = scale vector
x1 y1 z1
x2 y2 z2 = rotation matrix of camera
x3 y3 z3
I seen reference to the negative Z axis being the view but not sure what that means exactly. Any hints? Is my understanding correct? I tried searching these forums but never found any definitive information on what parts of the matrix are for what.
Thank you.
