3D object segmentation is foundational for fields like robotics, 3D generation, and virtual object manipulation. Traditional methods often depend on Vision Language Models (VLMs) using text prompts, which can limit their ability to handle complex, unlabeled datasets. Enter SAMPart3D, a pioneering zero-shot framework that segments 3D objects into detailed parts across multiple granularities—without relying on predefined text prompts. By eliminating text-based prompts and adding advanced segmentation capabilities, SAMPart3D sets a new standard in scalable, flexible 3D object part segmentation.
Removing Text Prompts for Scalable 3D Segmentation
A key innovation of SAMPart3D is its text-free approach to segmentation, which allows for efficient processing of vast, unlabeled 3D datasets. This approach leverages vision foundation models that distill essential 3D features, providing the ability to scale up and learn rich 3D priors. For instance, SAMPart3D successfully integrates with the massive Objaverse dataset, tackling non-standard objects and capturing intricate details. This allows it to segment highly varied objects, making it adaptable for real-world applications in diverse fields.
Hierarchical and Flexible Part Segmentation
SAMPart3D introduces a click-based hierarchical segmentation tool, enabling users to control the granularity of segmentation with a simple click. Similar to GraCo in 2D, SAMPart3D allows for hierarchical segmentation of 3D objects, from large, broad segments down to intricate, fine-grained parts. By adjusting the scale, users can control the segmentation detail, enhancing applications such as 3D editing and part-level animation. For example, as shown in tests with a 3D windmill model, users can modify parts individually, adjusting the angle or shape of specific components for custom animations.
PartObjaverse-Tiny: A New Benchmark for 3D Segmentation
Current datasets often lack the complexity needed to fully evaluate 3D segmentation tools. In response, SAMPart3D’s developers introduced PartObjaverse-Tiny, a benchmark with a diverse range of objects and complex part structures. This benchmark enables a more thorough assessment of segmentation models, making SAMPart3D’s capabilities stand out against other zero-shot segmentation frameworks. Experimental results on this benchmark highlight SAMPart3D’s superior performance, producing high-fidelity part segmentation across a diverse set of objects.
Streamlined 3D Model Customization and Editing
One of the standout features of SAMPart3D is its direct application in 3D model customization and editing. By generating segmentation results that are directly usable in tools like Blender, SAMPart3D simplifies workflows for creators, enabling part-level edits without manual segmentation. This allows for a more efficient process in refining and personalizing 3D models for applications in VR, animation, and game design.
SAMPart3D marks a transformative advance in 3D segmentation, addressing the limitations of traditional methods by removing text dependency and adding flexibility across multiple granularities. With its innovative hierarchical segmentation and new benchmark, PartObjaverse-Tiny, SAMPart3D sets a new standard in scalable, zero-shot 3D part segmentation. This development is poised to enhance various fields, empowering creators with precise control for editing, animation, and model customization in unprecedented ways.
