Abstract: Generative models have recently made remarkable progress in the field of 3D
objects. However, their practical application in fields like engineering
remains limited since they fail to deliver the accuracy, quality, and
controllability needed for domain-specific tasks. Fine-tuning large generative
models is a promising perspective for making these models available in these
fields. Creating high-quality, domain-specific 3D datasets is crucial for
fine-tuning large generative models, yet the data filtering and annotation
process remains a significant bottleneck. We present MeshFleet, a filtered and
annotated 3D vehicle dataset extracted from Objaverse-XL, the most extensive
publicly available collection of 3D objects. Our approach proposes a pipeline
for automated data filtering based on a quality classifier. This classifier is
trained on a manually labeled subset of Objaverse, incorporating DINOv2 and
SigLIP embeddings, refined through caption-based analysis and uncertainty
estimation. We demonstrate the efficacy of our filtering method through a
comparative analysis against caption and image aesthetic score-based techniques
and fine-tuning experiments with SV3D, highlighting the importance of targeted
data selection for domain-specific 3D generative modeling.
