html5-animation

I need to do an animation frame-by-frame changing a background-position of an element. I need to do this WITHOUT easing or linear animation, just changing the background-position. Is it possible to achieve with css3 animation? Yes it is via the new step-function easing curves property. Instead of "ease-in" etc. use "step-start" or "step-end" which will make the transition happen instantaneously either at the beginning or end of the time period specified in transition-duration. You can also have multiple steps: "steps(N, start | end ])" which will have the transition happen in equally spaced

I have trying to achieve SVG element's animation while adding dynamic DOMs for its animation with jQuery. I generate DOMs with JS, so HTML page does not have any elements for this animation. When I add it dynamically, animation will not start in Chrome(16), however it works with FF(8) The animation would perfect is I remove that dynamic doms which are generated with JS and put them static into HTML page. I have created fiddle for it at : http://jsfiddle.net/cjP6K/7/ where I have put one svg dom static into HTML page, then I have cloned that element with jQuery on document ready, In this scene,

What's the best way to emulate a spinning roulette wheel in HTML5? The wheel spinning should be controllable by some input (i.e., speed of spinning based on some user input). The wheel labels should blur as the wheel spins fast, but as the spinning slows, the labels on the wheel become more and more readable. Are there HTML5 libraries that support this, or do the animations need to be programmed by hand? This also needs to be supported on iOS devices. It can be done in a few lines of CSS. http://jsfiddle.net/YNBxz/1/ – CSS-only (see in Chrome or Safari). http://jsfiddle.net/YNBxz/2/ – with

What is the most accurate way to measure framerates, i.e. FPS, in modern HTML5 browsers? I'm specifically interested in FPS for Canvas animations. http://weblogs.mozillazine.org/roc/archives/2010/11/measuring_fps.html will tell you that trying to measure framerate by counting how often your setTimeout runs is not accurate. The browser can run your Timeout callback multiple times between screen paints. Turns out Mozilla has a window.mozPaintCount https://developer.mozilla.org/en/DOM/window.mozPaintCount available, which should provide an accurate FPS. However, this only works for Mozilla. There

I have a flash animation I am trying to convert to HTML5. Now I have taken out all the images. For example in the hand animation, I have taken images of all hand images. I have made the canvas with the base drawing but I don't know how to replace those images frame by frame. function draw(){ var canvas = document.getElementById('canvas'); if(canvas.getContext){ // canvas animation code here: var ctx = canvas.getContext('2d'); var lhs = new Image(); lhs.src = "images/left_hnd_1.png"; lhs.onload = function(){ ctx.drawImage(lhs, 293, 137); } } else { // canvas unsupported code here: document

In a test application i have a canvas with a simple rectangle on it. The method draw is called every 100ms. as you can see from the code i'm using the Mousewheel to scale everything. What happens now is, that everything is scaled, but i.e. when the rectangle is at 10px,10px and i have the mouse right over it the rectangle is not under the mouse anymore after scaling. (Which is of course right because all units are scaled up to. But what i want to is, that the mouseposition is the "center of the zooming action" like in google maps so the content which is under the mouse before scaling, is under

Hi is it possible to have an effect of flipping a page like a book for HTML5? If so how is it done? Thanks in advance! Here is another page-flip animation done with CSS Animations UPDATE: LINK BROKEN. The methodology is based on Roman Cortes's inspired original . The way this is constructed is that each right page is double-nested inside two divs. The inner div is rotated by 30 degrees around a rotation point above the page inside an outer div so that the page comes into view. The outer div is also rotated into view around the same rotation point by about 15 degrees. It is configured with an
