The pos estate is a price within the variety [0, 1] indicating the present place of the animation, the place zero is at first and 1 is whilst the animation is completed. The rendering functionality in directory nine. 10 handles the calls to the fncs services. directory nine. 10 Rendering Animations jewel. reveal = (function() { ... functionality renderAnimations(time, lastTime) { var anims = animations. slice(0), // replica checklist n = anims. size, animTime, anim, i; // name before() functionality for (i=0;i
