AI 3d Scene Generator

What is scene-dreamer.github.io?

SceneDreamer is a GitHub-hosted project developed by researchers from Nanyang Technological University, focusing on generating 3D scenes from collections of 2D images. The goal of this project is to produce diverse landscapes that maintain 3D consistency, offer clear depth, and allow for free camera movement. Featured in IEEE Transactions on Pattern Analysis and Machine Intelligence (TPAMI) in 2023, SceneDreamer utilizes a combination of advanced 3D scene representation, generative scene parameterization, and neural volumetric rendering techniques to generate photorealistic 3D scenes from random noise.

How does scene-dreamer.github.io work?

SceneDreamer generates unbounded 3D scenes from 2D image collections through a series of steps:

1. Data Collection: It begins with a set of 2D images from various sources.
2. 3D Scene Representation: The system employs a neural network to learn a 3D representation of the scenes shown in the 2D images.
3. Generative Scene Parameterization: Next, the system generates parameters for the 3D scenes, ensuring consistent depth and style across the output.
4. Neural Volumetric Rendering: Finally, neural networks are used to render the 3D scenes, enabling free camera movement and photorealistic results.

The project is open-source and available on GitHub, where detailed setup and usage instructions are provided.
