ComboVerse: Compositional 3D Assets Creation Using Spatially-Aware Diffusion Guidance



Generating high-quality 3D assets from ... image is highly desirable ... Though promising results ... in single object generation ... often struggle to model ... multiple objects.


... present ComboVerse, a 3D generation framework that produces high-quality 3D assets with complex compositions by learning to combine multiple models.


1) ... first perform an in-depth analysis of this ``multi-object gap'' from both model and data perspectives.


2) Next, with reconstructed 3D models of different objects, ... seek to adjust their sizes, rotation angles, and locations to create a 3D asset that matches the given image.


3) To automate this process, ... apply spatially-aware score distillation sampling (SSDS) from pretrained diffusion models to guide the positioning of objects.


... ComboVerse achieves clear improvements over existing methods in generating compositional 3D assets.
