Our past experiments demonstrated that there is no benefit to building a general purpose WebGL renderer for EaselJS. Modern canvas implementations already do a great job at rendering arbitrary 2D content on the GPU, and they use native code to do the heavy lifting. We’re not going to beat them in JS. However, it is possible to realize huge performance benefits with WebGL if you place appropriate r

Please note that SpriteStage & SpriteContainer classes are now deprecated and have been replaced by the much faster and easier to use StageGL! As WebGL becomes more widely supported in browsers, we’re proud to announce that after working in collaboration with Mozilla, a shiny new WebGL renderer for EaselJS is now in early beta! Following research, internal discussions, and optimizations, we’ve man

We are happy to announce that another tagged dot-release of CreateJS has been pushed live to GitHub! We have worked hard on stabilizing the libraries and APIs, and have made lots of great improvements in this release. EaselJS Updates to mouse interaction, events, and features Lots of documentation updates, corrections, and better code samples Bug fixes, including several identified by the communit

Update: Limited support for calculating bounds has been added. Read more here. I get asked a lot why EaselJS does not support width and height values on DisplayObject instances. It’s an obvious feature to add, and would enable a lot of secondary functionality. On the surface it seems like it would be easy to implement, but gets a lot messier when you start digging in. Shapes Vector shapes are one

The latest version of TweenJS (1.0) has a completely rebuilt plugin model, and ships with a much more robust set of plugins. … Continue reading → Scaling and Stretching with the ScaleBitmap Class We are always looking for ways to optimize, simplify, or create better workflows in CreateJS, and the ScaleBitmap is a great example of this. Using an old Flash approach, the ScaleBitmap class, shipped in
