I have an Odyssey in the "space" of D3.js, until I found GreenShock.

I wish have found it earlier! I didn't need the (big?) data, just the animation!


Chapter 1

Here is the problem of my gsap-animated page.


When the page opens there is a black strip on top of image instead of 

 $("#field"), {scaleY: 2}


(If you replay, it corrects).


After 5 sec  begining  the animation,  an instand flare fires  in frond and under the tank!

Thanks for the demo. Its always good to work with a reduced test case, so I removed all the extraneous stuff.

I'm able to see that on initial page load, sometimes, you will see a big black bar (as if the image is being pushed down), however when you press the "run" button in codepen it renders correctly (small, equal height bars on top and bottom of image). Still looking into why this is happening.


As for your flare, isn't that just part of the image?

That's because the image hasn't finished loading when that JavaScript runs, so it literally has no height at all, thus transformOrigin:"50% 50%" ends up basically at the very top edge (because again, there's no height, thus 50% of 0 is 0). Either use px like transformOrigin:'550px 157px' or set up an event listener to delay the execution of the code until the image has finished loading. Does that clear things up?
