4d objects

For an object living in a 4D space, visualizing is harder, but writing down equations is not. Your 4D space is just a set of 4-uplets $(x,y,z,t)$, and you can still project points $(x_0,y_0,z_0,t_0)$ in your surface onto "hyperplanes", such as the set defined by the equation $t_0=0$. live 4d result sgp hari ini
