Design of LEGO Assembly Transformation

This paper presents a design method for LEGO assembly transformation, addressing the problem of reassembling an existing LEGO model into a different target shape while optimizing the use of available bricks. This conference paper presents the foundational design framework that was subsequently extended in the journal version (Computer-Aided Design and Applications, 2018).
