This isn’t the fourth dimension of time we’re talking about, but another spacing dimension. See this added paragraph of the present text for a drawing of it. First, imagine a color that doesn’t currently exist.

For those not familiar with Redshift, it's a different render engine for Cinema 4D that uses your graphics card to do the rendering. This is the zero curvature case that completes the constant curvature and the other with positive constant This gives you an unforgettable experience and will always leave a smile on the faces of children and adults alike.
