With the release of iOS 7, I was anticipating some big leaps forward in browser performance. What I found was quite surprising. Is anyone else experiencing the same thing? Here's a quick [and very casual] video showing what I discovered:
I'm going to take a deeper look into CSS Animations and how they fit (or don't fit) into a modern animator's workflow. You'll see exactly where some of the pain points are for a typical project and how they can bring your workflow to a grinding halt.
Making a DOM element draggable isn't terribly difficult - there are jQuery plugins and even some native HTML5 capabilities in newer browsers. But generic dragging is kinda boring. What about smooth, natural momentum-based continuation after the user releases the mouse (or touch on mobile devices)? What about imposing bounds and edge resistance and silky-smooth redirection to certain landing values that you provide? Or flick/drag scrolling with bounce-back that doesn't look awkward? Or instead of dragging to change the position of an element, what if you want to spin it? Maybe you even want to track the momentum and let it come to rest naturally or rig it to glide to a stop at a certain value, Wheel-of-Fortune style? Yeah, that's a lot more complex. In fact, it can be a real drag to build (sorry, the pun was irresistible).
We're excited to announce several new features in the GreenSock Animation Platform (GSAP) 1.12.0 that will increase not only "real" performance, but "perceived" performance as well. The innovative lagSmoothing() feature allows GSAP to automatically heal from CPU spikes that cause lag, all while maintaining perfect synchronization between all animations. And the new "lazy" rendering helps avoid layout thrashing when many animations start simultaneously.
“ With the incredible functionality, and the mind-blowing customer service, the price of Club GreenSock admission is well worth it! ”
“ @greensock it’s a great library that many people love, and I know you care deeply about performance :) ”
Paul Lewis, @aerotwist
“ It's shocking the @w3c didn't use @greensock as a model of how to do animation via code. Did they even ask animators what they use? ”
Elliot Geno, @ElliotGeno
“ GSAP is just miles and miles ahead of any animation library out there. Great work! ”
“ This stuff is so incredibly amazing I can't believe it. The level of details and options put into these things and the natural instinct GreenSock has for solving everyday problems is impressive. ”
Jens Ahrengot Boddum
“ GreenSock has encouraged me to play with the code, to dream up new and exciting things to do. ”
“ GSAP makes my job fun, because it allows me to focus on creating rich, engaging web experiences, while GSAP handles much of the implementation details behind the scenes. ”
“ After searching around the web for alternatives, I found GreenSock to be the most performant. ”
“ If every library were as robust and reliable as GreenSock’s, the world would be a much better place for software engineers and their clients. I can't think of a better designed or better performing tool, and as a bonus, it's fun as heck to play with. ”
