🚀 Method Overview

RDG is an efficient asymmetric UNet-based super-resolution network for solving the real-time rendering problem. We first propose a dynamic feature modulator for capturing a precise structura information, and then incorporate auxiliary G-buffer information to guide the decoder to generate detail-rich, temporally stable results.

📚 Dataset Generation

We use the Cycles engine to render the scene model and generate the dataset. The figure above illustrates the detailed rendering settings, where we set the maximum number of light samples to 1000, the maximum number of light reflections to 12, HR videos have a spatial resolution of 1920×1080 and 480×270 for their LR counterparts, and the frame rate of the camera is set to 24 FPS. The collected dataset covers different scenarios such as complex textures and geometries, glossy reflections, and fast-moving objects.
