Viewcrafter
Overview :
ViewCrafter is an innovative approach that leverages the generative capabilities of video diffusion models and the coarse 3D cues provided by point-based representations to synthesize high-fidelity new viewpoints of general scenes from single or sparse images. The method progressively expands the area covered by 3D cues and new viewpoints through iterative view synthesis strategies and camera trajectory planning algorithms, thereby increasing the generation range of new viewpoints. ViewCrafter can facilitate various applications, such as creating immersive experiences and real-time rendering by optimizing 3D-GS representations, as well as promoting imaginative content creation through scene-level text-to-3D generation.
Target Users :
ViewCrafter is ideal for professionals such as 3D modelers, visual effects artists, game developers, and virtual reality content creators who need to synthesize high-fidelity new viewpoint videos from single or sparse images. It provides an efficient method for generating high-quality video frames while precisely controlling camera posture, which is crucial for creating realistic 3D environments and visual effects.
