I am not sure about the usage of the macro DT_THETA(dt)[i]. It calculates the angle(θ) of the rigid-body, every time step? What is i?

I encountered this problem too, do you remember the meaning of DT_THETA(dt)[1]?

DT_THETA(dt)
orientation of body-fixed
axis vector

0 means along x axis
1 - y
2 - z
