SharpGL

Build status codecov GuardRails badge

Unlock the power of OpenGL in any .NET application. SharpGL wraps all modern OpenGL features, provides helpful wrappers for advanced objects like Vertex Buffer Arrays and shaders, as well as offering a powerful Scene Graph and utility library to help you build your projects.

Example of SharpGL

Check out the Samples, they're a great place to start learning how to use SharpGL.

Getting Started

SharpGL is made up of a number of packages, you can install whichever package or packages you need!

Package Link Overview
SharpGL SharpGL Core All OpenGL functions wrapped and ready to execute, as well as all OpenGL extensions.
SharpGL.SceneGraph SharpGL SceneGraph The SceneGraph library contains a full class library which models key 3D entities.
SharpGL.Serialization SharpGL Serialization The Serialization library contains utilities to load data from Discreet, Wavefront and Caligari file formats.
SharpGL.WPF SharpGL WPF SharpGL for WPF includes the Core as well as OpenGL controls to drop into your WPF app.
SharpGL.WinForms SharpGL WinForms SharpGL for WinForms includes the Core as well as OpenGL controls to drop into your WinForms app.

Install SharpGL packages with NuGet, either by using the Package Explorer or the Package Manager tool, e.g:

PM> Install-Package SharpGL

Compatibility

SharpGL has built in support for OpenGL support, newer functions can be loaded on demand as needed. The table below shows the compatibility across frameworks and platforms.

OpenGL

Currently SharpGL has built in bindings for OpenGL 4.0 - functions from later versions can be loaded at runtime as needed.

Framework Compatibility

All components support the .NET Framework 4.0 onwards, .NET Core 3.0 onwards and .NET Standard 2.1 onwards. Some components also support earlier versions.

Component .NET Framework .NET Core .NET Standard
SharpGL 4.0+ 2.0+ 2.0+
SharpGL.SceneGraph 4.0+ 2.0+ 2.0+
SharpGL.Serialization 4.0+ 2.0+ 2.0+
SharpGL.WinForms 4.0+ 3.0+ 2.1+
SharpGL.WPF 4.0+ 3.0+ 2.1+

Platform Comptability

Compatability across platforms is supported via framework specific components.

Platform Support
WinForms on Microsoft Windows via SharpGL.WinForms
WPF on Microsoft Windows via SharpGL.WPF
UWP on Microsoft Windows Work in Progress
Xamarin on Microsoft Windows Work in Progress
Xamarin on MacOS Work in Progress
Xamarin on Linux Work in Progress

Legacy Versions

The Visual Studio 2017 version of the codebase, which supports the .NET Framework only, is available on the release/2.x branch. However, this branch will not be maintained going forwards. The current mainline still supports the .NET Framework.

Developer Guide

To build the code, clone the repo and open the SharpGL, Samples or Tools solution. The Extensions solution is used for the Visual Studio Project Templates and requires additional components - you can find out more on the Wiki on the 'Developing SharpGL' page.

You can also use the following scripts to run the processes:

Script Notes
config.ps1 Ensure your machine can run builds by installing necessary components such as nunit. Should only need to be run once.
build.ps1 Build all solutions. Ensures that we build both 32/64 bit versions of native components.
test.ps1 Run all tests, including those in samples.
coverage.ps1 Create a coverage report. Reports are written to ./artifacts/coverage
pack.ps1 Create all of the SharpGL NuGet packages, which are copied to ./artifacts/packages.

These scripts will generate various artifacts which may be useful to review:

artifacts\
  \tests                  # NUnit Test Reports
  \coverage               # Coverage Reports
  \packages               # NuGet Packages

Releasing

To make and publish a release:

  1. Update the *.csproj files with the new version number
  2. Create the version tag (e.g. git tag v3.2.1)
  3. Push the code and tags (e.g. git push --follow-tags)

AppVeyor will automatically push the release to NuGet and GitHub.

Sample Applications

There are a large number of sample applications that show how to use SharpGL. Check out the 'Samples' solution to see the samples that are available.

WinForms - Ducky Sample

This sample shows how to load an object file with materials, using the Serialization library. It also has great support for internationalization (thanks odalet)!

Ducky Sample

This sample demonstrates:

  • Loading *.obj files and associated materials
  • Building polygons from *.obj files
  • Arcball rotation

Note that this sample uses immediate mode OpenGL, which is officially deprecated.

WinForms - Extensions Sample

This sample shows how to use OpenGL extensions. It demonstrates this by using the 'bump map' extensions.

Note that this sample uses immediate mode OpenGL, which is officially deprecated.

Extensions Sample

WinForms - Hit Test Sample

This sample shows how to use to perform hit testing with SharpGL. It uses the Scene Graph to support this.

Note that this sample uses immediate mode OpenGL, which is officially deprecated.

Extensions Sample

WinForms - Modern OpenGL Sample

This sample shows how to use modern OpenGL capabilities which are Shader based, by showing a vertex and fragment shader.

Extensions Sample

WinForms - Native Textures Sample

This sample shows how to load textures into OpenGL using pure OpenGL functions. However, the Texture object from the SceneGraph will be much easier to use!

Note that this sample uses immediate mode OpenGL, which is officially deprecated.

Native Textures Sample

WinForms - Particle Systems Sample

This sample shows how to build a simple particle system with OpenGL.

Note that this sample uses immediate mode OpenGL, which is officially deprecated.

Native Textures Sample

WinForms - Polygon Loading

This sample shows how to load polygon data with the Scene Graph and Serialization libraries.

Note that this sample uses immediate mode OpenGL, which is officially deprecated.

Native Textures Sample

WinForms - Radial Blue

This sample shows how to use a Radial Blur effect in OpenGL.

Note that this sample uses immediate mode OpenGL, which is officially deprecated.

Native Textures Sample

WinForms - Render Contexts Sample

This sample demonstrates the different types of render contexts which are available, and how they affect performance and the extensions available.

Native Textures Sample

WinForms - Render Trigger Sample

This sample shows different ways to render; either on a timer or on demand.

Native Textures Sample

WinForms - Scene Sample

This sample demonstrates the Scene Graph which can be used to manage and render geometry.

Note that this sample uses immediate mode OpenGL, which is officially deprecated.

Native Textures Sample

WinForms - SharpGL Textures Sample

This sample demonstrates how textures can be loaded using the SharpGL Textures object, which greatly simplifies texture management.

Note that this sample uses immediate mode OpenGL, which is officially deprecated.

Native Textures Sample

This sample demonstrates how to use NV_DX_interop(2) to accelerate drawing using DirectX.

WPF - Object Loading Sample

This sample demonstrates how to load objects in a WPF OpenGL project.

WPF - Simple Shader Sample

This sample shows how to use a simple shader.

Simple Shader Sample

WPF - Tea Pot Sample

This sample shows how to quickly and easily render geometry.

Simple Shader Sample

Documentation

All documentation is available on the Wiki.

SharpGL Visual Studio Extensions

There are project templates available for SharpGL WinForms and WPF projects - just search for SharpGL on the Visual Studio Extensions gallery, or get the extensions directly:

Please be aware that these extensions have not been maintained over time and I am looking for support in maintaining them.

Credits, Sponsorship & Thanks

SharpGL is written and maintained by me. Special thanks go to the following contributors:

  • robinsedlaczek - Code and documentation updates, tireless patience while I get through a backlog of work!
  • odalet - amazing work on internationalization and making the serialization code work in all locales
