basic 4d

The basic idea is to consider a time interval \([t_0, t_0+\Delta t]\), and knowing the positions and velocities of each node of the 4D surface model at time \(t_0\), we can compute its positions at time \(t_0+\Delta t\) (we predefined a threshold value \(\delta \) for the thickness of the 4D surface and any motion between two frames is clamped . queenstown pools 4d . sky77 4d
