Utilization of Plane Tessellation for Paper Folding and Geometrical Transmittance Pattern for Lampshade Design

In the field of lampshade design, paper folding method has been highly utilized as the non-flat texture by paper folding method can generate beautiful luminance distribution. Especially, if the non-flat texture is composed of curved surface units, luminance distribution in the units is continuous and visually soft. And the method combining non-flat pattern and geometrical transmittance pattern has been already proposed to overlap luminance distribution caused by non-flat texture and that by transmittance pattern. In this paper, plane tessellations are introduced to expand diversity of lampshade design. Two methods were proposed with single tessellation and multiple tessellations. With single tessellation method, a tessellation was used for both paper folding and geometrical transmittance pattern. With multiple tessellation method, multiple tessellations were used for paper folding and geometrical transmittance pattern respectively. To verify the effect of the combination, lampshades with non-flat texture and geometrical transmittance pattern were manufactured and brightness distributions of them were measured.
