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).

NaroCAD is a fully fledged and extensible 3D parametric modeling CAD application. It is based on OpenCascade.

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.

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.

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.

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

VTK.NET is a .NET wrapper for the Visualization Toolkit. With it, you can write Windows Forms applications in C#, managed C++, Visual Basic, or J#. It includes a Windows Forms Control for drag and drop design of forms.

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.

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.

This Windows application supports compilation of FX effect files and HLSL shader files using fxc command line compiler included in DirectX SDK. You can compile many files at time or one file with different settings.

CsGL is OpenGL for the .Net Framework, providing support for OpenGL 1.1 - 1.4 and numerous extensions.

Occasionally you find a triangle mesh, containing errors you would like to fix. With TriMM, the TriangleMesh Manipulator, you can repair, alter or convert triangle meshes stored as .OBJ, .OFF, .PLY or .STL files. You can also create some simple meshes.

2licht's aim is to provide a collection of wrappers for the popular Irrlicht Engine (http://irrlicht.sf.net/). It is still in development; the first wrappers to be released will be the C and Object Pascal interface; followed by a .NET library.

This is project is created to perform boolean operation using DirectX 9.0 with .NET 2.0 and other supported dlls. This is not a final build as i am working on the same. -- The suggestions are always welcome. Thank You.

3DProS is a programming tool. It helps people create 3D animations, design custom 3D controls and solve lots of graphic problems easily, just by drag and drop. Besides a built-in language called MathScript, it also supports Free Pascal and MinGW C++

ActFX is a 3D engine written in C # using XNA and Framework.NET ActFX è un 3D engine scritto in C# utilizzando XNA e il Framework.NET

This was going to be a 3D CRPG written in c++, now it will probably be some sort of CRPG written in C# with DriectX 9.

Intended to be a cross-platform 3D engine and toolkit using the Tao framework and allowing C#/F#/.NET developers to target Mac OS X and Windows with a single build. Also includes accessory tools for managing builds and ports of your game product.

In our plans to develop scientific, three-dimensional model of the cosmos, with its stars, planets, nebula,etc. According to him, you can move, to walk between different solar system, planets and stars seen

A generic hierarchical file format. BHM can be seen as the binary equivalent of XML. It allows flexible hierarchies of any type of data, in a platform-independent way. BHM however trades XML's readability for compactness and speed of processing.
