Excited to share our work, Know3D, which connects LLMs' reasoning ability and knowledge to 3D generative models. This increases the controllability and plausibility of unseen parts in the generated 3D shapes. Paper: Project page:

We can control what would be hallucinated in the back view using text prompts and make it more structurally plausible. HF: Code is coming soon:

This is such a clever and practical idea! 🔥 Integrating LLM knowledge to guide unseen regions in 3D diffusion models is a game-changer for making generated shapes way more plausible and controllable. The back-view examples look super impressive love how a simple text prompt can fix structural issues without any extra 3D data. Congrats on the work, Can't wait for the code release. This feels like a big step toward more intelligent 3D generation.

I wonder if the fine-tuned Qwen also have the editing capability of the front-view image in a way that maintains the original pose? Would be interesting to enable the 3D edit. Very nice work!

Yes, I think this could be a promising way to achieve 3D editing without using 3D editing training data, by leveraging strong image editing. In our current version, we only finetune it to generate the backview, which cannot do this. But I think this is promising.

3D-LLM: Injecting the 3D World into Large Language Models paper page: Large language models (LLMs) and Vision-Language Models (VLMs) have been proven to excel at multiple tasks, such as commonsense reasoning. Powerful as these models can be, they are not grounded in the 3D physical world, which involves richer concepts such as spatial relationships, affordances, physics, layout, and so on. In this work, we propose to inject the 3D world into large language models and introduce a whole new family of 3D-LLMs. Specifically, 3D-LLMs can take 3D point clouds and their features as input and perform a diverse set of 3D-related tasks, including captioning, dense captioning, 3D question answering, task decomposition, 3D grounding, 3D-assisted dialog, navigation, and so on. Using three types of prompting mechanisms that we design, we are able to collect over 300k 3D-language data covering these tasks. To efficiently train 3D-LLMs, we first utilize a 3D feature extractor that obtains 3D features from rendered multi- view images. Then, we use 2D VLMs as our backbones to train our 3D-LLMs. By introducing a 3D localization mechanism, 3D-LLMs can better capture 3D spatial information. Experiments on ScanQA show that our model outperforms state-of-the-art baselines by a large margin (e.g., the BLEU-1 score surpasses state-of-the-art score by 9%). Furthermore, experiments on our held-in datasets for 3D captioning, task composition, and 3D-assisted dialogue show that our model outperforms 2D VLMs. Qualitative examples also show that our model could perform more tasks beyond the scope of existing LLMs and VLMs.
