Introducing 3DVADER: Bridging the Gap Between 2D and 3D Object Generation

Generating images and editing them has become easier than ever with the help of generative AI models. These models act like your personal designer, allowing you to guide the process of creating the images you want to see.

But what about 3D object generation? While image generation has reached a point of photorealism and there have been advancements in video and audio generation, the focus on 3D object generation has been lacking.

The Challenge of Bridging 2D and 3D

We live in a 3D world filled with static and dynamic 3D objects. However, bridging the gap between 2D and 3D is a challenge. This is where 3DVADER comes in.

Introducing 3DVADER: Bridging the Gap

3DVADER specifically tackles the challenge of combining the geometric details of the 3D world with modern image generation techniques. Unlike previous methods, 3DVADER offers a fresh perspective on 3D content generation by addressing scalability and diversity.

Instead of relying on conventional autoencoders, 3DVADER introduces a volumetric auto decoder. This unique approach maps a 1D vector to each object, eliminating the need for 3D supervision and accommodating a wide range of object categories. By utilizing rendering consistency, articulated parts can also be accurately modeled.

One of the obstacles in 3D object generation is the lack of a robust and versatile 3D dataset. However, 3DVADER solves this by leveraging multi-view images and monocular videos to generate 3D-aware content. It can handle the challenges of limited object poses by offering robustness to ground-truth or estimated pose information during training. Additionally, 3DVADER supports datasets spanning multiple categories, ensuring scalability.

Overall, 3DVADER is a novel approach to generating static and articulated 3D assets. Its core is a 3D auto decoder that can utilize existing camera supervision or learn this information during training. It outperforms current state-of-the-art alternatives.
