rtx

Path tracing renderer and utilities for three.js built on top of three-mesh-bvh.

Combined repo for the RTX-Remix runtime and toolkit

THE FIRST DLSS 5 MANAGER

Implementation of Peter Shirley's Ray Tracing In One Weekend book using Vulkan and NVIDIA's RTX extension.

LuxCore source repository

DLSS 5 NR on your whole Windows desktop, in real time with Boost, FG, etc. RTX 30/40/50, 12 languages, user presets, recording with audio, one-window mode.

High-Performance Rendering Framework on Stream Architectures

A High Performance Compute Shader Based Mesh Pathtracer in Unity3d without RT Cores

Puts DLSS 5 neural rendering into games that never shipped it, and brings the game's own DLSS up to date - super resolution, ray reconstruction, frame generation. Scans your library, picks one of eight routes, fetches every part from its publisher at run time, then says what happened. One exe, no admin; uninstall puts the game back.

A New Cross-Platform 2D 3D Game Engine

RTX Global Illumination (RTXGI)

Lighthouse 2 framework for real-time ray tracing

Embeddable physically based renderer

Vulkan Real-time Path Tracer Engine

Carefully-crafted PBR textures for every block, faithful to vanilla, in three variants: Vanilla RTX, Normals and Opus. The default ray-traced look for Minecraft Bedrock.

Data visualisation and ray tracing in Python based on OptiX 9.1 framework.

Graphics API wrapper is written in C++ on top of DirectX 12, Vulkan and Metal 4. Provides main features including ray tracing.

Vulkan ray tracing glTF 2.0 renderer — RTX path tracer with PBR materials, AI denoising (DLSS, OptiX), and scene editing. NVIDIA open-source sample.

Oh my God, it's free for everyone; we won't sell this.
