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.

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.

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
