For the relationship between three-dimensional space and buildings or to landscapes, it is possible that many imaginary spaces and buildings can be created within three-dimensional space. As we try to put the buildings in three-dimen-sional space onto a flat sheet of paper and interpret the picture from different perspectives, we can bring forth the visual system of our own, with the creative style a bit like that of Cezanne and Picasso. If we look at objects and landscapes from different angles as multiple angles and appearances are placed in the same picture and then intertwined with different horizontal lines, the author will always pay special attention to the structure of building, so that the picture can be presented in a flat plane, or it regarded as real building. To use geometric shapes, one can have sketched out the subtle relationship between two-dimensional plane and three-dimensional space, the world beyond the plane, and the interactive relationship between the physical and virtual.
