    Wacom’s inking technology allows users to exchange their creations between solutions that use the WILL technology. Wacom’s technology allows the ink to remain editable and can be used in different WILL compatible apps, software and services.
  • will collaboration cg

    with ink

    WILL enables real time collaboration with ink. Write and draw on the same canvas without being in the same location or using the same device. Just like real ink on paper, visually beautiful natural strokes are rendered in real time with direct response on the screen.

WILL is supported on:

  • iOS 6 or higher with Objective C
  • Android 4 or higher with Java
  • Windows 8.1 with Windows Store XAML applications with .NET and C++
  • Web with HTML5/Javascript on any browser with full WebGL support

These platforms are not officially supported.  Please contact Wacom and share your intent.

Any development environment for the supported platforms is generally suitable.  However, the demo projects provided along with the SDK require the following IDEs:

  • Eclipse ADT for Android
  • XCode 5 for iOS
  • Visual Studio 2013 or higher and Windows 8.1 or higher

No, WILL is designed to work with any kind of pointer input devices.

Not necessarily, it works with touch or mouse too.

Wacom's browser plugin provided along with drivers or HTML5 Pointer Events when they become more widely supported by browsers.

Productivity demo project is utilising retained mode graphics, while the Creativity demo is utilising immediate mode graphics (directly rendering in bitmap).

Yes, WILL is designed to work in conjunction with other rendering engines, like font type renderers or general 2D graphics libraries.

Yes, images can be imported on the WILL canvas as OpenGL/DirectX/WebGL textures.

WILL SDK provides built-in support for the WILL stroke file format.  If you have questions about file compatibility for your existing application, please contact us under willdevelopers@wacom.com

It is more optimal for handwritten content compared to SVG.  It provides for uniform input independent graphical representation across devices unlike InkML.

Yes, inking tools are entirely parametrized and application developers can design their own tools.

SurfaceView or TextureView on Android, CAEAGLLayer on iOS, SwapChainPanel on Windows 8, HTMLCanvas on Web.

Yes, demo projects provide examples of that.

WILL Core modules are coded in C++ and they are compiled to ASM.JS (subset of Javascript) using Emscripten.

This happens when you open the Creativity and Productivity Demo simultaneously.  It is caused by the fact that both demos share the WILLComponents.xcodeproj as a sub-project.  The solution is to close both demo projects and then to have only one of them open at a time.  

For approximately 1 hour of handwriting with 'felt' tool (9353 strokes having 194090 total control points) the resulting file size is 1103 KB.

For approximately 1 hour of handwriting with 'felt' tool on iPad3 Model MD331FD/A, the performance stats are:

  • File size:  1103 KB
  • Strokes count:  9353
  • Total control points count:  194090
  • Total time for loading file and rendering:  3.595228 seconds
