Helix Toolkit

Helix Toolkit is a collection of 3D components for .NET Framework.

HelixToolkit: Core components shares across different projects.

HelixToolkit.Maths: Modified Math library carried over from SharpDX project to support System.Numerics library.

HelixToolkit.Geometry: Geometry builder library to support common shapes.

HelixToolkit.SharpDX: Custom 3D Engine and Scene Graphs based on SharpDX(DirectX 11).

HelixToolkit.Avalonia.SharpDX: XAML/MVVM compatible Scene Graphs for supporting AvaloniaUI based on HelixToolkit.SharpDX.

HelixToolkit.Wpf.SharpDX: XAML/MVVM compatible Scene Graphs for supporting WPF based on HelixToolkit.SharpDX.

HelixToolkit.SharpDX.Assimp: SharpAssimp 3D model importer/expoter support for HelixToolkit.SharpDX Components.

HelixToolkit.WinUI.SharpDX: XAML/MVVM compatible Scene Graphs for supporting WinUI based on HelixToolkit.SharpDX.

HelixToolkit.Wpf: Adds variety of functionalities/models on the top of internal WPF 3D models (Media3D namespace).

Examples: Please download full source code to run examples.

Project Build

Visual Studio 2022.

Documentation

Automated Documentation Generation

This project uses DocFX to automatically generate comprehensive API documentation from C# XML comments.

View Documentation:

• API Documentation: Automatically generated and deployed to GitHub Pages
• Build Locally: See Source/Documentation/README.md for instructions

Build Documentation Locally:

Windows:

cd Source
build-doc.cmd

Linux/macOS:

cd Source
./build-doc.sh

The documentation is automatically built and published via GitHub Actions on every push to the main branch.

For more details on writing and building documentation, see the Documentation README.

Notes

1. Right-handed Cartesian coordinate system and row major matrix by default

HelixToolkit default is using right-handed Cartesian coordinate system, including Meshbuilder etc. To use left-handed Cartesian coordinate system (Camera.CreateLeftHandedSystem = true), user must manually correct the triangle winding order or IsFrontCounterClockwise in raster state description if using SharpDX. Matrices are row major by default.

2. Performance Topics for WPF.SharpDX and UWP.

3. Following features are not supported currently on FeatureLevel 10 graphics card:

FXAA, Order Independant Transparent Rendering, Particle system, Tessellation.

4. Wiki and useful External Resources on Computer Graphics.
