I came up with the engine myself, it uses a simple algorithm to find the x,y,z plot after rotating each point, in this case, eight points for a cube. If you want to know them, I'd be happy to comment them here.
The first thing to consider is how to plot in 3D, I simply plotted ( x , y + z ). This may cause a little problem in looks since the cube in the scenario is a little taller than it is wide, but it still works.
