There are unknown way to visualize subspace, or vector spaces. You can stretching the width of the x axis, for example, in the right line of a 3d stereo image, and also get depth, as shown below. L R |____| |______| TIP: To get the 3d depth, close one eye and focus on either left or right line, and then open it. This because the z axis uses x to get depth. Which means that you can get double depth to the image.... 4d depth??? :O It's even possible to add 4d depth to a isometric cube, by move left face of the right cube along x axis, and leave the left cube unchanged. Would be awesome, if someone make a game that way! Nice video! :-)
it is an issue of camera panning , a form of projection along x axis. each flame in this clip need much render time that will make huge lag on a game playing.
