I need help for animation in flutter - animation

I wanted to know if it is possible to replicate this in Flutter, I know of the existence of Heroes but I know that they are only applicable with images.
What would be the best solution?
Example

Yes, this is replicable in Flutter.
Hero doesn't need to wrap only images you can experiment with any element for some really cool animation effects.
Consider reading this - https://flutter.dev/docs/development/ui/animations/hero-animations

Three.js objects masking video

We are creating an animated datavisualization.
We are trying to find out how to use objects to use as a clip mask a video below using three.js. It could be a sprite sheet animation if thats easier.
Here is an example video of the end result:

It must work in IE10, which seems to be a problem finding a solution.
Can someone share an example? Im kind of a newbie to three.js
Let me know if you have any questions.
Thanks in advanced!

create a simple (and visible!) UI slider in Unity 5

![enter image description here][1]please I need some help, this should apparently be something very simple and basic to do, but maybe I'm missing something.
I'm quite newbie to Unity3d, I had no much problem with creating a somewhat flashy 2.D scene (I mean 2D with different layers in Z level), scripts, etc. But I'm having trouble to create a "UI Slider" object: when I create it, it just shows nothing on screen. How can I make it visible? I just need to create a very simple, plain slider whose value can be controlled at runtime by means of a script.
thanks.
Well.. since you give nothing to go on, I suggest that you take a look at a tutorial for the UI:
https://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/using-the-ui-tools
If you have troubles after this tutorial, come back with an example of your problem to make people more willing to sacrifice their time in helping you.
Hope this is somewhat useful
Take a look at the Unity3D docs here.
http://docs.unity3d.com/Manual/script-Slider.html
It should have what you are looking for.

Animation background image in WP8

I have a pattern and set it as a background. I want to make it go up forever (like scene in run endless game)
Please help me.
No tiling effect built into Windows Phone 8 by default. You have to just use None, Fill, Uniform, and UniformToFill if you don't want to build your own or use someone else library/code.
You can easily achieve a Tiling effect by using a Canvas and some rudimentary algebra and graphical calls. But best to learn from example, I guess:

OpenCV compare images

I need help with OpenCV to solve the following problem:
I have some pictures of one place
Each photo compare with the first
in the photos except the first I need to draw the frames where there was a change
Can anyone advise me or recommend a prime example?
That sounds like a job for background substraction.
BackgroundSubtractorMOG2 is the class you will probably want.
I have not used it myself, but here is a tutorial

Canvas sprite library or tutorial

I am looking for some simple library for javascript to manage animations.
I need something realy simple, just to "parse" animation to frames. I want to handle everything by myself, i want just to know, how many frames is in animation and how to get the frame i want.
I did some digging on google, i found one which is realy nice (sprite.js) but it is too big and it will force me to rewrite my app.
Is there simple lib, or a tutorial how to work with animated images? (gif and others).
There is no straight way to get single frame from gif in JavaScript.
