Hello, I know this neccessarily doesnt have much to do with JME, however, it does have to do with learning shader language which i shall use in conjunction with jme.
now, i understand 3d vectors and 3d matrix pretty well, however, i am confused of the structure/use/utilization of this 4th dimension
if i am correct they look like
XYZW - 4D Vector
4D matrix
XYZW
X - - - -
Y - - - -
Z - - - -
W - - - -
am I correct on this? how does the W interact which such objects?
Thank you.
A xyzw matrix / quaternion defines a (relative) rotation. The first three values are the axis and the w value is the rotation around that axis.
