Instant-NGP Mip-NeRF360 3DGS Ours Ground truth Instant-NGP Mip-NeRF360 3DGS Ground truth Ours Figure 1. FA-NeRF is a frequency-aware framework to capture both the overall scene structure and the high-definition tiny details within a single model, e.g., the clear petal of flowers and sharp texture of wings of the butterfly. Instead, other methods give an over-smooth rendering and lose excessive details. Please see the Supplementary Video for an immersive roaming experience.
