## What it is
Veldrid is a low-level, portable graphics library for .NET that provides a unified, API-agnostic interface to the GPU for rendering and compute workloads. It supports Direct3D 11, Vulkan, Metal, OpenGL 3, and OpenGL ES 3 backends, enabling high-performance 2D and 3D applications across desktop and mobile platforms.

## Use cases
- render 3D graphics in a cross-platform .NET application
- build a custom game engine on top of a portable GPU abstraction
- write GPU compute shaders from C#
- create 2D and 3D simulations or graphical tools in .NET
- target Vulkan, Metal, Direct3D, and OpenGL with one codebase
- build high-performance graphical applications for desktop and mobile

## When to choose
- you need a portable, API-agnostic GPU abstraction in .NET
- you want low-level control over rendering pipelines, buffers, and command lists
- you need to support multiple graphics backends (D3D11, Vulkan, Metal, OpenGL) from a single codebase
- you are building a game engine, simulation, or rendering tool in C#

## When to avoid
- you want a high-level game engine with built-in scene management, physics, or asset pipelines
- you need a library with active public development and frequent updates (the maintainer has stopped publicly sharing updates since 2023)
- you are not working in the .NET ecosystem
- you only need simple 2D drawing where a higher-level UI or canvas library would suffice

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, simulation
- domain: graphics, cross-platform
- platform: cross-platform, windows, dotnet
- tags: gpu-rendering, compute, vulkan, direct3d, metal, opengl, opengl-es, 3d-graphics, 2d-graphics, game-engine-foundation, game-development, macos, linux, android, ios
