Helix Toolkit is an open source 3D library that is licensed under the MIT license. The MIT license is very permissive and permits use in proprietary software. The library is based on .NET and is currently focusing on the WPF platform. The goal has been to make it easy to work with 3D in WPF, and also provide features that are not included in the standard WPF 3D visual model. Adds variety of functionalities/models on the top of internal WPF 3D models (Media3D namespace). dds variety of functionalities/models on the top of internal .NET Core WPF 3D models (Media3D namespace). Custom 3D Engine and XAML/MVVM compatible Scene Graphs based on SharpDX(DirectX 11) for Universal Windows App. Custom 3D Engine and Scene Graphs based on SharpDX(DirectX 11) for netstandard and .NET Core. Custom 3D Engine and XAML/MVVM compatible Scene Graphs based on SharpDX(DirectX 11) for WinUI 3 (Project Reunion - experimental).

glTFast enables use of glTF™ (GL Transmission Format) asset files in Unity. It focuses on speed, memory efficiency, and a small build footprint while also providing 100% glTF 2.0 specification compliance. glTFast supports the full glTF 2.0 specification and many extensions. It works with Universal, High Definition, and Built-In Render Pipelines on all platforms. Move or copy glTF files into your project's Assets folder, similar to other 3D formats. glTFast uses custom shader graphs that you have to include in builds in order to make materials work. If materials are fine in the Unity Editor but not in builds, chances are some shaders (or variants) are missing.

Open-source, cross-platform 3D rendering engine for .NET and Mono. The Axiom Engine is a high-performance C# port of the powerful OGRE engine and provides full support for DirectX, OpenGL and XNA on Windows, Linux, Android, iPhone and Windows Phone.

ClutterFlow is a CoverFlow clone for the Banshee media player. ClutterFlow uses the Clutter toolkit to harness the OpenGL powers. For more info: http://gitorious.org/banshee-community-extensions/pages/ClutterFlow

GLTF/GLB Windows Shell Extension: This shell extension automatically adds thumbnail images to .glb files in Windows File Explorer and provides a right click menu option to generate a 3D preview image for .gltf files. Supports multi-file select and directory processing. Pre-built Windows x64 installer available at https://buymeacoffee.com/nathancrews/e/255640 LAS/LAZ Pointcloud Windows Shell Extension: This "quick viewer" shell extension provides a Windows File Explorer right click menu option to quickly generate 3D preview images for large and small .las and .laz files. (Disclaimer: Processing time depends on compute hardware) Typical processing time for 100mb .las is about 2 seconds. 25mb .laz file process in about the same times. Files are processed in parallel using available CPU cores. Pre-built Windows x64 installer available at https://buymeacoffee.com/nathancrews/e/255641

OpenArena is a 3d game creation engine. It is a rendering system that can be used for more than just games but it is targeted at games. The basic use being create some game media textures models maps and config files for physics and rules.

As of 2012-10-02, the well-known Tao project became officially abandoned and superseded by another project called OpenTK. However, since OpenTK follows a different way than Tao did, this project tries to carry on with the original design and ideas, but with cutting edge features. The ultimate goal is to have a 1:1 OpenGL binding for .NET, which supports OpenGL 4.x. The project tries to keep as much of the original goals as possible, including licensing, etc.

Irrlicht .NET CP is a .NET wrapper of the famous Irrlicht rendering engine. It provides a full, entirely cross-platform 3d rendering engine working with any .NET language. Moreover it has an extensions library which adds a lot of features to the engine.

An easy to use managed graphics engine. Utilises OpenGL, Direct3D9, and Xna through an abstraction layer. Accompanied by a number of other helpfull tools, for example to simplify input and networking.

The project has moved to https://github.com/greenya/irrlichtlime ----------- The Irrlicht Lime is a .NET wrapper for the Irrlicht Engine. It wraps most of API available in native library, easily allowing you to use 2D/3D graphics in your app, written in C#, VB.NET or other .NET language. Currently Lime is being develop under Visual Studio 2010 with .NET Framework 4.0. It includes bunch of examples and IntelliSense documentation. Lime is not a distinct "engine", it is a wrapper with almost the same architecture witch native Irrlicht Engine has. You do not need to download/compile Irrlicht Engine, wrapper already has it and ready to be used straight from the box.

V3D-Viewer is a Dicom and "Philips V3D 3DRA" Medical Volume Viewer based on .Net and the VTK library. With marching cubes, 3d planes and (3D texture) volume rendering, including histogram transparency and intensity curve selection tool.

The first 3D game engine built in C# for .NET, predecessor to the Visual3D Game Engine (https://www.poweraccess.net/visual3d-game-engine), an All-in-One Game Development Tool for Next-Gen 3D Games, MMOs, Simulations and Virtual Worlds powered by Microsoft XNA.

A tool for finding missing or corrupt images in a sequence. Also generates basic statistics from Exif data. Targeting time-lapse and render-farm users when using post-processing tools such as After Effects.
