4K4D: Real-Time 4D View Synthesis at 4K Resolution

Figure 1 . Photorealistic and real-time rendering of dynamic 3D scenes. Our proposed method reconstructs a 4D neural representation from multi-view videos, which can be rendered at 1125×1536 resolution with a speed of over 200 FPS using an RTX 3090 GPU while maintaining state-of-the-art quality on the DNA-Rendering [12] dataset. It is also noteworthy that our method reaches over 80 FPS when rendering 4K images with an RTX 4090. Detailed performance under different resolutions using different GPUs can be found in Tab. 5.
