Text2Light: Unleash Immersive Realism through Text-Driven Photorealistic 3D Scene Rendering

Opportunity 

Embark on a journey into the heart of immersive digital experiences with this state-of-the-art AI technology, capable of generating photorealistic rendering of HDR 3D scenes. Given a text-driven scene description as input, Text2Light generates a high-quality HDR panorama.  

As the metaverse and virtual reality reshape the way we interact with the digital world, the demand for such AI-driven HDR 3D scene generation has never been greater. Whether it's exploring breathtaking virtual landscapes or designing the next iconic virtual destination, this free-form text photorealistic rendering technology sets the standard for what's possible. High-quality high dynamic range images (HDRIs), particularly HDR panoramas, are crucial in creating photorealistic lighting and 360-degree reflections for 3D scenes in computer graphics. These HDRIs are in high demand due to their ability to imbue scenes with stunning realism. However, the process of capturing HDRIs is notoriously challenging, underscoring the need for a versatile and user-friendly generative model that allows even non-experts to intuitively control the generation process. Despite significant advancements in the field, existing state-of-the-art methods continue to grapple with the synthesis of high-quality panoramas, especially for complex scenes.  

Technology 

Text2Light generates photorealistic rendering of HDR 3D scenes. This zero-shot text-driven framework empowers users to generate HDRIs with resolutions exceeding 4K, all without the need for paired training data. Text2Light interprets a free-form textual description of the scene provided by the user, synthesising a corresponding panorama in a low dynamic range (LDR) and low resolution format. This step serves as the foundation upon which the subsequent enhancements are built. Following panorama generation, Text2Light employs super-resolution and inverse tone mapping to elevate the LDR panorama in both resolution and dynamic range, resulting in a final HDR panorama of exceptional quality.
