Traditional methods have limitations, but we have a game-changing solution for you! 4K4D is an innovative AI solution that tackles the challenges faced by previous approaches in dynamic view synthesis. It offers remarkable rendering speed while maintaining high-quality results, thanks to its unique combination of a 4D point cloud representation and a hybrid appearance model. The 4D point cloud sequence captures the structure of the dynamic scene, with each point's position modeled as a learnable vector. A 4D feature grid assigns feature vectors to points, which are then processed by MLP networks to predict the point's radius, density, and spherical harmonics coefficients. This approach enhances optimization and robustness. The hybrid appearance model combines the spherical harmonics model with an image blending model to accurately represent the scene's appearance. The image blending network is independent of the viewing direction, allowing for pre-computation after training, thus improving rendering speed. This model leverages the information captured by input images, resulting in enhanced rendering quality. Extensive experiments have shown that 4K4D achieves significantly faster rendering speeds while outperforming state-of-the-art methods in terms of quality. With an RTX 4090 GPU, this solution can achieve up to 400 FPS at 1080p resolution and 80 FPS at 4K resolution.
