Creating a 3D shape design from free-hand sketches is a challenging task due to the sparse and ambiguous information from sketches. In this work, we propose DualShape, a sketch-based 3D shape design ...

In this paper, inspired by the creative mechanisms of human imagination, which concretely supplement the target model from ambiguous descriptions built upon human experiential knowledge, we propose a ...

In this work, we explore how to effectively generate large-scale 3D scenes using the coarse-to-fine paradigm. We introduce a framework, the Pyramid Discrete Diffusion model (PDD), which employs ...
