showing elements within boundary

[vipulsharma144]

Hello 

in the given pen i want to achieve :

 

1) Only the elements inside the circle area to be visible with ease effect of gsap.i.e on increasing the radius they must appear onto screen via gsap and on decreasing similarly should disappear

2) the elements to appear or disappear should be draggable with the container as the max limit of circle.

3) the elements should be clickable.

4) the circle opacity should be reversed i.e right now it is rgba(0,0,0,0.8) inside the circle i want it to be outside the circle so as to give the selection effect

 

waiting for help.

Thank you

Thanks for demo.

 

Unfortunately these are not easy tasks or directly related to GSAP. I think you have your work cut out for you. 

 

You may want to research css clip path or SVG masking techniques.

Frankly, I'm not confident you will get great results combining them with Google Maps (but I'm not entirely sure)

 

The rest of your questions seem related to mapping coordinates of elements in different containers to circular bounds of another element, and that just isn't something GSAP has built in at the moment. 

 

The only thing of marginal help I can reccomend is this demo that Blake created: http://codepen.io/osublake/pen/YXpdYN

It does circular hitTest() which perhaps you could reverse engineer in some fashion to detect when an element is within a certain radius.
