The delicate design of paper pop-ups fascinates people of all ages. Since the 1940s, Lego becomes a well-known tool in the field of constructing three-dimensional models. In 2016, a V-fold type Lego pop-up book was published on the Lego ideas platform. This amazing work has led to our computer-assisted tools for designing Lego pop-ups.\nAlthough there have been various studies on paper pop-up books and Lego construction, there is no related research that combines the two. Therefore, based on the observation and analysis of Lego pop-ups, we propose three Lego pop-ups mechanisms. We analyze how to arrange the Lego bricks to form a reasonable Lego pop-up structure through general formulation. Based on the proposed mechanisms, we design a system to generate an initial layout design from the input of two-dimensional images and user-specified mechanisms and parameters. Then, through the proposed optimization model, we compute a stable structure that is easy to assemble in a feasible time even the complexity of the three-dimensional is infinite. We verify the feasibility of the proposed method by various kinds of input images of our system. |
