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.

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).

Particle Effect For UGUI is a Unity package for rendering ParticleSystem effects directly inside the uGUI canvas system. It uses Unity mesh baking APIs and CanvasRenderer instead of requiring a separate camera, render texture, or canvas. Particle effects can be sorted alongside regular UI elements by sibling order. The package supports Mask and RectMask2D components for clipping particles within interface regions. Trail modules, multiple materials, CanvasGroup alpha, and animated material properties are also supported. It works across overlay, camera-space, and world-space canvases as well as URP and HDRP rendering pipelines.

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

ColladaLoader is a free open source C# Library that enables developers to load and display Collada 3D Model files (.DAE) in DirectX 10 using the SlimDX SDK. Partitial .X file support. More info: http://www.tomsdevshack.be/projects/colladaloader

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.

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.

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

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.

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

Icarus Scene Engine is a cross-platform, CLS-compliant 3D framework, integrating open source APIs into a cohesive all-open-source, all .NET solution. For Windows, MacOSX & Linux. Uses OpenTK, OpenGL, OpenAL APIs for graphics and audio. Runs on Mono/.NET. Links to FFMpeg for streaming video, and FreeType as a temporary conversion mod to bring fonts into a native XML format. Binary builds of Icarus will be infrequent, roughly every 18 months or so, the GIT code updates regularly on a weekly or twice-weekly basis (or faster if there are urgent issues).

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
