Summary

LichtFeld Studio addresses the need for high-performance real-time rendering in 3D Gaussian Splatting. It offers researchers and developers a C++ and CUDA-based implementation designed for speed and efficiency, enabling advanced neural rendering applications. The project aims to provide a powerful, accessible, and free alternative to commercial solutions.

How It Works

This project implements 3D Gaussian Splatting using modern C++23 and CUDA 12.8+ for maximum performance. It features a modular architecture separating core logic, training, and rendering components. Key innovations include an MCMC optimization strategy for better convergence and bilateral grid appearance modeling to handle per-image variations, contributing to its claimed superior rasterization speed.

Quick Start & Requirements

Pre-built binaries for Windows are available via releases and nightly builds, requiring no compilation. Users need an NVIDIA driver version 570 or newer. Detailed installation instructions are available on the LichtFeld Studio Wiki.

Highlighted Details

• Achieves 2.4x faster rasterization compared to baseline implementations.
