StyleSDF: High-Resolution 3D-Consistent Image and Geometry Generation
This addresses the challenge of creating realistic 3D content for applications like graphics and VR, representing an incremental improvement by combining existing techniques.
The paper tackles the problem of generating high-resolution, 3D-consistent images and detailed 3D shapes from single-view RGB data, achieving results with visual and geometric quality superior to state-of-the-art methods at 1024x1024 resolution.
We introduce a high resolution, 3D-consistent image and shape generation technique which we call StyleSDF. Our method is trained on single-view RGB data only, and stands on the shoulders of StyleGAN2 for image generation, while solving two main challenges in 3D-aware GANs: 1) high-resolution, view-consistent generation of the RGB images, and 2) detailed 3D shape. We achieve this by merging a SDF-based 3D representation with a style-based 2D generator. Our 3D implicit network renders low-resolution feature maps, from which the style-based network generates view-consistent, 1024x1024 images. Notably, our SDF-based 3D modeling defines detailed 3D surfaces, leading to consistent volume rendering. Our method shows higher quality results compared to state of the art in terms of visual and geometric quality.
