Product Information
Key Features of ViewCrafter: Taming Video Diffusion Models for High-fidelity Novel View Synthesis
ViewCrafter takes advantage of the powerful generation capabilities of video diffusion models and the coarse 3D clues offered by point-based representation to generate high-quality video frames with precise camera pose control.
High-fidelity Novel View Synthesis
ViewCrafter can generate high-fidelity novel views of generic scenes from single or sparse images using video diffusion models.
Point-based Representation
ViewCrafter uses point-based representation to provide coarse 3D clues for generating high-quality video frames with precise camera pose control.
Iterative View Synthesis Strategy
ViewCrafter adopts an iterative view synthesis strategy that involves iteratively moving cameras, generating novel views, and updating the point cloud.
3D-GS Optimization
ViewCrafter can facilitate more consistent 3D-GS optimization by progressively completing the initial point cloud and synthesizing novel views.
Real-time Rendering
ViewCrafter can facilitate immersive experiences with real-time rendering by efficiently optimizing a 3D-GS representation using the reconstructed 3D points and the generated novel views.
