Differences between WILL 2 and 3
What are the differences between WILL 2 and 3 and do you have any guidance for migrating?
WILL 2 for Windows is based on asm.js (http://asmjs.org/faq.html).
The underlying technology used for inking is WebGL.
The latest version of WILL 2 is v.2.1.0.
The underlying technology used for inking is 2D.
WebGL is also available for complex tools used in sketching apps.
WILL 3 significantly reduces the complexity of canvas interaction and works as an extension of 2D context - it just adds inking functionality.
There is no migration guide between WILL 2 and 3 because WILL 3 provides completely new concepts of path building and technology.
Rendering primitives is almost the same but data format is completely different.
A converter from a WILL 2 to a WILL 3 data file is available if needed.
WILL 3 has several distributions:
wacom-digital-ink.js - UMD distribution - This is used for CDN imports or for bundling.
For bundles additional configuration is required - there are native dependencies which should be excluded from the bundle.
wacom-digital-ink-esm.js - ECMA6 distribution This is used with import/export statements (the next version name will be updated to wacom-digital-ink.mjs)
wacom-digital-ink-cjs.js - CommonJS build This is compatible with NodeJS env (the next version name will be updated to wacom-digital-ink.cjs)
Provides ECMA6 for NodeJS
The package should be available in npm repository one day (depending on legal authorisation).
WILL 3 does not have tutorials or samples yet, but a demo app (based on CDN syntax) and API documentation have been provided.
The demo app provides the basic concepts of Vector and Raster inking. The source is available here: https://github.com/Wacom-Developer/sdk-for-ink-web
You can access the demo app here: https://will3-web-ink-demo.azurewebsites.net
Tool Configurator app:
For WILL 2 see https://developer-demos.wacom.com/ToolConfigurator
For WILL 3 see http://ink-designer.trafficmanager.net/
This provides many new features. Path building is much more powerful and path point geometry configuration is handled much more precisely.
WILL 3 comes with tilt support and control on everything related to path building.
WILL 2 has support for variable size and alpha color channel only - many properties can be varied in WILL 3.
