"Bits-to-Photon: End-to-End Learned Scalable Point Cloud Compression for Direct This repository contains the official implementation for the paper: Frequency-Modulated Point Cloud Rendering with Easy Editing (CVPR 2023 Highlight). 000 points where it starts lagging. In this paper, we present Point2Pix as a novel point renderer to link the 3D sparse point clouds with 2D dense image pixels. This method first attempts to bridge the 3D Gaussian Splatting and point cloud rendering, which includes several cascaded modules. While commodity GPUs provide a continuously growing range of features and sophisticated methods for accelerating compute jobs, many state-of-the-art solutions for point cloud rendering still rely on the provided point primitives (GL_POINTS, POINTLIST, …) of graphics APIs for image synthesis. vsgPoints - VulkanSceneGraph Point Cloud rendering Cross platform, open source (MIT license) C++17 library and example set for rendering large point cloud data using VulkanSceneGraph.
