  Creating 3D textured meshes using generative artificial intelligence has
garnered significant attention recently. While existing methods support
text-based generative texture generation or editing on 3D meshes, they often
struggle to precisely control pixels of texture images through more intuitive
interaction. While 2D images can be edited generatively using drag interaction,
applying this type of methods directly to 3D mesh textures still leads to
issues such as the lack of local consistency among multiple views, error
accumulation and long training times. To address these challenges, we propose a
generative point-based 3D mesh texture editing method called DragTex. This
method utilizes a diffusion model to blend locally inconsistent textures in the
region near the deformed silhouette between different views, enabling locally
consistent texture editing. Besides, we fine-tune a decoder to reduce
reconstruction errors in the non-drag region, thereby mitigating overall error
accumulation. Moreover, we train LoRA using multi-view images instead of
training each view individually, which significantly shortens the training
time. The experimental results show that our method effectively achieves
dragging textures on 3D meshes and generates plausible textures that align with
the desired intent of drag interaction.
