Creating the shape of the basic element is the most important step. Starting with the extrusion of the circle to create a pillar that branches off in four directions in the upper part, the tree-resembling structure is developed. Nevertheless, in contrast to a tree, the form is very regular. In the plan view, it can be inscribed into the square.
Thanks to the branches, going from the central point of the square to its corners, four triangular areas are created. In this step, mathematical calculations have to be applied to set the bending level of edges and specify points to create a net of sub-structure within the triangular areas.
While one module is created, it is possible to multiply it in two directions to create a wireframe that resembles the building. The modules should join each other providing a continuous curvy cover.
