Abstract:Holes, thickness, layers, and functions are key operations of tessellation,whenever representing and materializing patterns in building surfaces. The first three formrelated operations can expand traditional patterns from 2D to 3D, and should be implemented through combination with specific material and construction techniques. Concurrently, the function, such as enclosure, lighting, insulation, shading, etc. is another sort of important elements for tessellation. In addition to developing the visual effects of patterns, rethinking tessellation can further integrate those patterns with material characteristics, joints, and functions, and can bring more possibilities to architectural design.
