Introducing Scene Dreamer: The Boundless 3D World Synthesizer

Step into the mesmerizing realm of Scene Dreamer, where the possibilities are as vast as your imagination. Scene Dreamer is an extraordinary generative model that bestows the power to conjure expansive 3D landscapes from the very fabric of randomness. What sets this tool apart is its ability to create these boundless realms without the constraints of predetermined 3D annotations, learning directly from the untamed wilderness of 2D image collections.

At its core, Scene Dreamer embodies a principled learning paradigm that combines three essential elements: an efficient and expressive 3D scene representation, a generative scene parameterization, and a masterful renderer that draws inspiration from the rich tapestry of 2D images.

Scene Dreamer harnesses the might of an ingenious bird’s-eye-view (BEV) representation, born from the graceful dance of simplex noise. This representation is composed of two intricate fields: the height field and the semantic field. The height field gracefully captures the undulating surface elevations of the 3D landscapes, while the semantic field weaves in the rich tapestry of detailed scene semantics. Together, they form the canvas upon which your dreams take shape.

What truly sets Scene Dreamer apart is its remarkable ability to encapsulate the essence of a 3D scene with quadratic efficiency. It masterfully disentangles the intricate interplay of geometry and semantics, all while ensuring a seamless and efficient training process.

Scene Dreamer introduces a revolutionary generative neural hash grid, carefully designed to parameterize the latent space, drawing upon the knowledge of 3D positions and the intricate semantics of the scene. This ingenious mechanism encodes a treasure trove of generalizable features across scenes, harmoniously aligning content in a symphony of creation.

Last but not least, Scene Dreamer employs a neural volumetric renderer, meticulously trained through adversarial processes using the wisdom gleaned from extensive 2D image collections. The result is nothing short of astonishing—photorealistic images that breathe life into the boundless 3D worlds you imagine.

Scene Dreamer shines as a beacon of creativity, capable of crafting vivid, diverse, and boundless 3D realms that far surpass contemporary methods. It’s a journey into the uncharted territories of limitless imagination.
