Helix Toolkit is a collection of 3D components for .NET, providing XAML/MVVM-compatible scene graphs and 3D rendering for WPF, WinUI, and Avalonia applications. It includes a custom DirectX 11-based 3D engine built on SharpDX, geometry builders, and 3D model import/export via Assimp.

Use cases

• render 3D scenes in a WPF application
• build 3D data visualizations in .NET
• import and export 3D models in C#
• create MVVM-compatible 3D scene graphs with XAML
• display 3D meshes and geometry in WinUI or Avalonia apps
• build a custom DirectX 11 rendering engine in .NET

When to choose

• you need 3D graphics in WPF, WinUI, or Avalonia with XAML/MVVM support
• you want a high-level .NET wrapper over DirectX 11 for 3D rendering
• you need 3D model import/export (Assimp) in a .NET application
• you're building scientific or engineering 3D visualizations in .NET

When to avoid

• you need cross-platform GPU rendering beyond Windows-targeted UI frameworks
• you want a full game engine rather than a component library
• your project is not on the .NET ecosystem
• you need Vulkan or modern graphics APIs (the next-gen engine is still experimental)
