ScaffoldM3C: A Multimodal Sequential Monte Carlo Framework for Generative Stable Construction Planning
ScaffoldM3C uses a multimodal Sequential Monte Carlo (SMC) model to autonomously plan 3D structure assembly. It generates stable, block-based plans by treating construction as a probabilistic next-block generation task. The model ensures physical stability by explicitly considering the utility of scaffolding blocks during the planning process, leading to superior physical stability and faster inference compared to existing methods.
