WebJun 8, 2024 · Photon mapping works by tracing photons from the light sources into the scene and storing these photons as they interact with the surfaces or volumes in the scene. KeyShot implements a full progressive photon-mapping algorithm on the GPU that’s capable of rendering caustics, including reflections of caustics. WebWe present a modied photon mapping algorithm capable of running entirely on GPUs. Our implementation uses breadth-r st photon tracing to distribute photons using the GPU. The photons are stored in a grid-based photon map that is constructed directly on the graphics hardware using one of two methods: the r st method is a multipass WebApr 10, 2024 · Low-level任务：常见的包括 Super-Resolution，denoise， deblur， dehze， low-light enhancement， deartifacts等。. 简单来说，是把特定降质下的图片还原成好看的图像，现在基本上用end-to-end的模型来学习这类 ill-posed问题的求解过程，客观指标主要是PSNR，SSIM，大家指标都刷的很 ... board games new 2022
