I know how to animate between routes, but how can these animations be made "interactive"? For example, rather than simply triggering a preset slide animation on swipe, I would like the animation to map directly to the user's drag gesture. Another side effect of this type of interaction is that a user should be able to start a transition, but then cancel it using the same gesture.
This sort of pattern seems important for building the sort of animated transitions seen in Google's Material Design. I can accomplish these transitions within a route, but for organizational reasons I would like to be able to do so between routes.
Any examples or descriptions of designs would be greatly appreciated.
I would do this :
Detect touchstart event and trigger behaviour
detect the finger position while moving, and shift your wrapper html element accordingly. Probably with css, like transform3d: translateX( ... )
on touchend, evaluate if the distance is enough to trigger route change
if not, animate back to original position with css transition.
You probably want to have a look at http://hammerjs.github.io/ for gesture detection.
Good luck !

I'm trying to build a similar demo to one of the examples

My problem is as I start using a scroll area, all the pointer events are grabbed by the scroll area and the canvas doesn't receives them anymore, I tried using pointer-events: none but this disables the scroll event as well. I feel like I'm missing something obvious, but I don't know whats the best way to keep the scrolling behavior while having the onClick,onPointerOver,...etc working on my mesh

I Want to create a slideshow of different images for a project with HTML, JS, and CSS. I want to create a scroll function that will move the image slides from left to right based on the movement of the mouse scroll.
If this sounds confusing this link shows exactly what I'm trying to do but due to my lack of experience, I have no idea how to accomplish this. Any ideas would help.

thank you
(I'm a beginner in programming)
The animations used on this site are called scroll-based animations, where the animation progress is controlled directly by the scroll position.
They are implemented by listening to the scroll event that is fired when a user scrolls and updating the styles of certain elements dynamically based on the scroll position.
You can create scroll animations from scratch using JavaScript or implement them using a library like GSAP ScrollTrigger (which is what this specific site uses).
I created a demo similar to the effect you're looking for here: https://codepen.io/nickcil/pen/yLVEZPa
This example uses ScrollMagic to track the scroll position and update the transform property of an element to make the squares move left as you scroll down the page.
How should I create a custom page transition which listens to tap and swipe/drag even?.Suppose, if the page is dragged right/left (while still holding), then drag/slide the page to the value of swipe/threshold. And when the tap is released, if value is equal to or greater than the center of the page or maximum threshold, slide to the next page (link), or else slide back to its original position. Example. I would like to apply it in my jquery mobile app. An example demo would be great. Thank you.
Use a JavaScript library, such as HammerJS for easy touch gesture handling. Swipe is probably what you are looking for.
Also TouchSwipe jquery plugin is commendable, because it's easy to implement and provides swipe, pinch, touch and threshold events and triggers:

I'm building an AngularJS app and am looking to do something a little tricky with animations that I'm not quite sure how to do. One aspect of the app entails animation between views in a panning manner, but the appearance of a single view needs to be maintained. For example, if there is a scene with a square in the center, on view-change that square would appear to leave the screen as if we were panning across (while other elements enter in), all without it feeling like the view has really changed.
I know that ng-animate provides a lot of powerful animation functionality, but I'm stumped on what the best way to maintain the appearance of a single view while transitioning between them is.
Does anyone have experience trying to do this or know of an animation library that would make this possible?
I'll update this question with possible solutions as I find them.
When a view is added, the following classes are added:
.ng-enter
.ng-enter.ng-enter-active
When a view is removed, the following classes are added:
.ng-leave
.ng-leave.ng-leave-active
You can attach CSS 3 transition styles to the classes to achieve the animation effect you want.
If I understand correctly, the 'leaving' animation should pan left to right, and fade-out, starting from a 0px offset. The 'entering' animation should also pan left to right, but fade-in, starting from a negative offset.
Here is an example:

I'm trying to find a Javascript snippet that I can archive the UIScrollView + UIPageControl effect of the iOS using Javascript and CSS3.
Generating the page control to a dot to each view and do the switching is very easy, but the complicated part it is to do the elastic movement.
I would want to do this myself, but it seems to much work to me, like hours of work, tried googling, but I not found anything. I don't like JQuery but the mobile framework doesn't seems to do this.
If I had to do this by myself, do you guys have any suggested approach? I'm thinking in using a parent div, with a bunch of divs inside for each view. Use the parent with overflow: hidden;
and attach event to the parent view and listen to drags and bind to the horizontal scroll offset. This would be a good way? or using css transitions with left or translate-x would be more smooth?
EDIT:
This is what I tried (not working very well): JSFIDDLE
Yeah,
Im not sure about touch swipes, although i think the 'activate' or 'touchstart' handler might be useful. Using CSS3 transitions to achieve the elastic movement is quite smooth, just alter the left or right style property of your internal div and the transfom will move from its current position to where you need it to be.
This is not the worlds bestt example but have a look here
