dc.description.abstractBrick elements are very popular and have been widely used in many areas, such as toy design and architectural fields. Designing a vivid brick sculpture to represent a three‐dimensional (3D) model is a very challenging task, which requires professional skills and experience to convey unique visual characteristics. We introduce an automatic system to convert an architectural model into a LEGO sculpture while preserving the original model's shape features. Unlike previous legolization techniques that generate a LEGO sculpture exactly based on the input model's voxel representation, we extract the model's visual features, including repeating components, shape details and planarity. Then, we translate these visual features into the final LEGO sculpture by employing various brick types. We propose a deformation algorithm in order to resolve discrepancies between an input mesh's continuous 3D shape and the discrete positions of bricks in a LEGO sculpture. We evaluate our system on various architectural models and compare our method with previous voxelization‐based methods. The results demonstrate that our approach successfully conveys important visual features from digital models and generates vivid LEGO sculptures.Brick elements are very popular and have been widely used in many areas, such as toy design and architectural fields. Designing a vivid brick sculpture to represent a three‐dimensional (3D) model is a very challenging task, which requires professional skills and experience to convey unique visual characteristics. We introduce an automatic system to convert an architectural model (a) into a LEGO sculpture (b) while preserving the original model's shape features. Real LEGO sculptures (c) can then be built according to the automatically generated results. The results demonstrate that our approach successfully conveys important visual features from digital models and generates vivid LEGO sculptures.en_US
