RainyGS: Efficient Rain Synthesis with Physically-Based Gaussian Splatting

b) Rainy Novel View Synthesis (a) Multi-view Rain Free Inputs (c) Rain Intensity Control Figure 1. Using multi-view images as input (a), RainyGS constructs 3D scenes with physically-based Gaussian Splatting techniques to enable efficient and photorealistic rain synthesis (b). Our approach provides users with flexible control over rain intensity, from light drizzle to heavy downpour (c), achieving high-quality, realistic rain effects in a computationally efficient manner.
