## What it is
OpenSceneGraph is an open-source high-performance 3D graphics toolkit written in Standard C++ and OpenGL, providing a robust scene graph technology. It is widely used in visual simulation, games, virtual reality, and scientific visualization, though new projects are directed to its successor, VulkanSceneGraph.

## Use cases
- render 3D scenes with a scene graph in C++
- build visual simulation applications
- create virtual reality or training simulators
- scientific visualization of 3D models
- load and render 3D model formats in a game or tool
- cross-platform OpenGL rendering engine for desktop apps

## When to choose
- you need a mature, battle-tested OpenGL scene graph in C++
- you maintain or extend an existing OSG-based application
- you need broad platform support including older Unix systems
- you target OpenGL rather than Vulkan

## When to avoid
- you are starting a new project - VulkanSceneGraph is the recommended successor
- you need modern Vulkan features or latest GPU capabilities
- you want a high-level game engine rather than a graphics toolkit

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, game-engine, simulation
- domain: graphics, simulation, cross-platform
- platform: cpp, windows, cross-platform
- tags: scene-graph, opengl, 3d-graphics, visual-simulation, cmake, vcpkg, game-development, macos, linux, ios
