## What it is
Pangolin is a lightweight, portable C++ utility library for rapid prototyping of 3D, numeric, and video-based programs, providing cross-platform OpenGL windowing, viewport management, and video input/output abstraction. It is widely used in computer vision and robotics to remove platform-specific boilerplate and visualize data interactively.

## Use cases
- visualize 3d point clouds and camera poses in c++
- abstract video input from cameras in a cross-platform way
- build opengl debugging tools for computer vision algorithms
- tweak algorithm variables live with sliders and a python console
- prototype slam or visual odometry visualization
- render offscreen for headless video processing

## When to choose
- you need quick interactive 3D visualization in C++ for vision or robotics research
- you want portable windowing and video I/O without platform-specific boilerplate
- you need live-tweakable variables and a scripting console during development

## When to avoid
- you need a full-featured GUI application framework with complex widgets
- you are building a production end-user application rather than a research prototype
- you need modern Vulkan or DirectX rendering rather than OpenGL

## Facets
- artifact type: library
- maturity: stable
- function: graphics, image-processing, video-processing, gui, developer-tools
- domain: computer-vision, graphics, robotics, cross-platform
- platform: cpp, windows, wasm, cross-platform
- tags: opengl, 3d-visualization, camera-input, prototyping, slam, linux, macos
