— Summary

In this paper, we investigate a remotely related question: shape transformation between LEGO models. While many computational algorithms have been developed to construct LEGO models, the problem of constructing a LEGO model using bricks from an existing model has not been explored in open literature. We propose two objectives to optimize the transformation: the movement cost and the reuse rate of LEGO bricks.

This journal page also groups the earlier CAD'17 conference version, which presented the initial LEGO assembly transformation framework.

Problem setting

In this paper, we investigate a remotely related question: shape transformation between LEGO models. While many computational algorithms have been developed to construct LEGO models, the problem of constructing a LEGO model using bricks from an existing model has not been explored in open literature. We propose two objectives to optimize the transformation: the movement cost and the reuse rate of LEGO bricks.

In the broader publication record, this work appears in Computer-Aided Design and Applications, 15(6):796–806. The visual notes below pair the paper’s original figures with a concise reading of the method, experimental setup, and reported results.

Method and visual evidence

The method combines domain-specific measurements with an algorithmic representation that exposes the relevant structure, then refines it into a reconstruction, correspondence, segmentation, measurement, or decision result.

The extracted figures below show the main pipeline and representative experimental evidence.

Results and impact

The evaluation reported in Computer-Aided Design and Applications, 15(6):796–806 uses the extracted figures above to show the method’s measurement, reconstruction, segmentation, matching, or diagnostic behavior on representative experiments. These visuals are paired with the paper’s quantitative or qualitative analysis to make the workflow easier to inspect from the homepage.

Source handling

I extracted 10 candidate image objects from paper.pdf and generated the compressed WebP figures used on this page.
