I am trying to make a mouse animation to interact with my space background, for example like : https://neokcs.com/ if you move your mouse near stars you will see a white line i want something like that if it is possible please give me the code.
Here, Particle JS. Check out this. There are many variances of background available with the same, you can customise it easily.

I am having difficulties on where to begin for what I want to do.
I want to create an image editor on my page. So, suppose that I have an image of a car. Now I want to be able to change the color of each part of the car (hood, doors, wheels, etc). So when I click on the hood of the car, I can go to a color picker and choose a color and then the hood's color will change to the color I selected.
My research has led me to using a canvas element in HTML5 but I have no idea where to begin.
I found a perfect example of what I am trying to do. User's are able to select any part of the shoe and change the color of that part of the shoe.
Can anyone lead me in the right direction to accomplish this?
Any help is appreciated.
You'd have to use JS for this. This other question seems like a good place to start. Change Image Design color Fabric js
On succession of a previous question I tried to find out if the next thing is possible:
Take you have a render, like a soccer player with a transparant background. You add this render to your html & css. The transparant parts are now part of the image 'box'; you can't click on links under the image transparant parts, but you can see them.
Is it possible to make these links clickable? Thus having the image as highest z-index, but still have the links clickable and working.
(the links have a lower z-index because their background then stops under the image, giving a nicer design)
(Or said otherwise: have a .png image with a transparant background not shown as a box, but as only the colored pixels. Preferable only in html/css)
I think it is not possible, to be honest. If you do not yet understand my question, maybe my previous will help you:
need help fixing the link's clickable area
You can use pointer-events to make an event (click in this case) bubble through to the layer below.
No, it's not possible from what I'm aware of. However you can do similar things to what you want that may be useful:
Turn an area into a link using <map>
Use pointer-events:none so that clicks are ignored on the top element
IE 10 provides the non-standard msElementsFromPoint method that allows you to "peek below" an element; you can do that inside the click handler and determine if the click point overlaps an anchor. If it does, triggering that element's click event would do what needs to be done.
Unfortunately I am not aware of similar functionality for other browsers or earlier versions of IE.
I have an idea that I would like your input on how it can be achieved. Essentially, I would like to have a page where page elements would be responsive and animated. Let me give you an example - let's say I point my mouse over a button or an image and it would play an animation like http://hakim.se/experiments/html5/magnetic/02/ around it while mouse is pointing over it, fading away if I point away from it.
Alternatively, it would be cool to have something like http://hakim.se/experiments/html5/trail/03/ flowing from current mouse position to the element that I would like to draw user's attention to. I have little idea on how this can be implemented, thinking that creating a overlay and using element's coordinates would be most appropriate but not 100% it can be done this way. Do you have any recommendations or suggestions on best practices, existing libraries / frameworks that may assist me with this?
Thanks!
I'm having trouble understand how DisplacementMapFilter works. Basically, I'm trying to create a revolving planet through a combination of fisheye/masking.
Also, how do I go about doing this via timeline? I'm not too familiar with coding within it, but this is more of an animation project than anything else, so classes are out of the question. Sorry for the lack of code -- I'm simply stuck.
As noted in the comments above, this probably only answers half the problem;
Generating a displacement map image isn't too difficult with the right tools. I'll assume you're using Photoshop, GIMP, Fireworks, or similar.
It's probably best to work on a 128x128 image or smaller with this method. Some editors have more specialised tools which let you work on pretty much any size of image, but this is a generic process that needs no special tools. You can always enlarge the end result, but the quality will begin to go down.
Start with a gradient fill. It should go from pure black on the left to dark red on the right (specifically 128,0,0). Add a vertical fill from black at the top to dark green at the bottom (specifically 0,128,0), and combine them with a LIGHTEN or ADD filter. You should now have an image which has black, red, green and yellow corners. Flatten it.
Copy this image to another layer / whatever the term-of-choice is for your editor. Apply whatever displacement filter you want to it (maybe a fish eye, maybe a manual smudge, maybe a perspective transform, anything)
Add a third layer between the two. Flood-fill it with dark yellow (128,128,0) and set it to ADD / ADDITION blend mode. Set the top layer to SUBTRACT / SUBTRACTION blend mode.
That's it. You should get a mostly yellow image which will function as a displacement map.
Update:
To use this in the example program (http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/filters/DisplacementMapFilter.html#includeExamplesSummary), replace the createBitmapData function with this:
private function createBitmapData():BitmapData {
return myBitmapObject.bitmapData;
}
where myBitmapObject is the instance name (I think) of your displacement Bitmap. There are tidier ways of setting that up, but this is the easiest.
On Google, move your mouse over the faded out +1 button. You'll notice the image animates with a type of glimmer? Like a light going across the image. They are using an image for this but I'd like to know how to do this in CSS3. Any ideas for on hover? Also, anyone know what this effect is called?
Thanks
In their case, they are using a sprite, and then animating through it.
Unfortunately, it's not yet possible to animate css3 gradients, and background-position seems to have no effect on it. You'll just have to do with images at the moment.
