While roughly charting reality, we should choose some of the proposed architectural motives and then, summing up these within a system of our own - keeping in mind an imaginary function - we shall create a new interior space.
     We can control the structure of perspective by carefully calculating of the credibility of backside squares. That's why it is so important to trace even hidden edges. The success of our construction is up to the nearest cubic tower's correctness.
     During the planning stage and even later, while setting of surface intersections and material rendering, we shall be firmly supported by subdivisions of our structural grid's basic lines.
