I want to create a 2D skeletal animation using JavaScript library to make interactive 2D animations in the browser.
I'd like to create a human body. Let's consider this simple scenario to better explain what I want to achieve. I have a text box where I can enter an instruction like "say Hi", then the body should raise a hand up and give hi five. I am working to draw the both images and make them show up at every time.
When Init() : I show the body (Image One)
When I request to say Hi : I show the next body taking the hands up (Image two)
And I do animation by creating a HTML5 canvas, the same way as: http://jsfiddle.net/FZyA3/
The problem is that I have to make more than 50 instructions. It's heavy to draw all the scenarios where I have common cases. Is there any open source character to use, like Three.js and babylon.js?
Is there any other better solution, like pixelising the arm and making it movable within an HTML5 canvas?

It's an editor which comes with an JS-runtime.

I'm looking to implement a video editing feature like that of featured here https://clideo.com/video-editor.
I'm planning to use Vue 3 with a Laravel backend, but is there an ideal framework to use for a web application like this, or should I just try to reverse engineer/hack my way to a working implementation?
Sorry if this is the wrong place to ask, I just haven't been able to find an answer.
Thanks
Video editor consist of two important parts
1)A Timeline that represents sequence.
2)A Output window to show output of timeline.
-Clideo uses div and html elements positioning to generate timeline but a better alternative is to use Canvas and draw a timeline on it just like in veed.io
-For video output again you have to use canvas and webGL to draw each and every frame one by one.
you wont be able to edit video on backend and send edited multimedia for each change user makes you need to find a way to do in on client using webcodec.
For the choice of framework if you are having canvas and webGL do all the rendering of timeline and output then it dosent matters you will spend more time with drawing functions.
Almost every video editor has a timeline. But only in some of it (https://wave.video/tools/video-marketing/promo-video-maker) is divided into several ranges. An additional advantage will be the grid on the line. You can also easily manage layers and frames.
I am making a math teaching web page (URL below) and want to use JavaScript to create a wipe-in effect of a Canvas drawing. As you can see on my page, I have drawn a series of rectangles in a pattern. When the student enters the correct answer, I want to draw Fig. 5 using a wipe-in effect. What would be the best way to do that?
My thought at first would be to create a function that draws the entire pattern, then cover it with a white box that decreases in size, but I would surmise that doing it that way would cause a fluttering effect rather than a clean wipe.
Any ideas for how best to accomplish this? Thanks in advance for the help!

I would like to implement an image collage, where the photos are arranged on the page within a 'Word' object.
This is really hard to explain, this maybe why I haven't found any examples on the web. But as an example, let's take the word 'HTML'.
I would like to create a shape on a canvas on the screen, and then have photos transition onto the screen (easing, sliding, flying) and then arranging themselves sporadically around that shape. Then have the images clickable/zoomable. If possible, draggable as well within the shape.
Now, my first question, is this achievable, and how would I go about doing something like this?
I don't know too much surrounding HTML5 canvas, and am using this project to get my teeth into it. So I would really like to know briefly how something like this could be done.
thanks!
You can do something like a mask in photoshop you would get an image with invisible area with the shape you want to mark and then put the world image in the background.

I'd like to know how to make the faces of a 3D slideshow interactive i.e adding links on it.If creating multiple faces or walls is the way to go does that mean I put a layer over each wall and is so how would I do that?
In the end each wall should be able to be treated individually but all still in this cube form.
This is the slideshow I'm talking about

Thanks alot for your time!!
Well, they aren't really html objects. The "walls" are created using the canvas tag - which basically just means javascript. If you want to make it more interactive, I'd recommend that you look into CSS animation instead. You could probably achieve the same results using CSS. Search google for CSS animated cube or something like that.
I'd like to display the image, then let the user create multiple rubber-band selections on the image. Each mouse-down creates an additional selection. Has anyone seen an implementation of this technique in javascript?
I did use this image cropper script. It uses a rubber band to select the crop area. The code is pretty simple to follow and you could probably modify it to do what you want. Selecting overlapping areas would probably be a bit of a challenge though.
