so I'm wanting to have various sized triangle particles fly in from a random direction (all over the screen) and then assembles to spell the word "Zoid". I have been looking and three.js looks to be the API that I should use for this kinda stuff.
What three.js example should I be looking at?
I am not looking for someone to make this for me, I am only wanting the name of the technique/animation.
http://anime-js.com/ take a look at this seems like a pretty good framework for animated javascript

Well, may there is a way to make curved shape div... or at least to fake it. All I want to do is to bend div as it looks like a bit curved in 3D. I don't need any features as in video. If there is a way to do this in javascript/jquery tell me plz.
Another possibility is to use the perspective CSS property, I created a web photo gallery wall using this method, with similar results that you are looking for.
I used this website to help me build my gallery:

I have background on Canvas 2D context, but i want to perform a 3D animation like this one, is Three.js library the best choice to do such animation? Can you point me to some useful tutorial or documentation that may help. Thanx in advance.
That's one of the most common choices.
As WebGL enables OpenGL without the need for libraries, you might also do it with just Vanilla JS but that would be harder as WebGL doens't offer much more refinement over the raw and crude OpenGL.
Apart three.js, you could also try GLGE or PhiloGL but as Three.js is the most popular I would recommend to go for it if you have no specific requirement.
Looks like the demo you linked to is using a canvas library called Clay.js. Not one that I've personally heard about until now. For 3d in canvas the most popular one I know of it Three.js as you already mentioned. It has the benefit of supporting webGL as well (browser based openGL variant).
Three.js has limited documentation and some examples but outside of some books you may buy there isn't a lot of hand holding. You basically need to dive in and start coding. Here are some online resources that may help you get started (not necessarily all focused on THREE.js):

To make it easier to work with THREE.js Jérôme Etienne created a project called tQuery which you can think of kinda like jQuery. A wrapper to make it easier to get your hands dirty. Here's a video where he shows how to create a webGL game in 10 minutes.
I'm trying to create line graphs like the one in the image below.
It needs to have a very light weight(in kb), and needs to have points that I could hover(for a tooltip about that point, like in the image). I don't need pie charts or anything like that, just line graphs like above.
I'm just not sure how to go about it best, I don't know canvas, and i'm assuming that might be pretty complex trying to do what I need with canvas. I know jQuery decently well.
I'm wondering: Is there a very light weight framework/plugin that would allow me to do just the bare essentials like in the image? If not, how would you suggest going about this with jQuery?
All I need are the lines drawn, with points that I could trigger a hover on, I can take care of the tooltip and all that, i'm just trying to figure out how to draw all the lines the match up with the grid, and get the little circle elements in the right position.
Thanks so much.
ps: light weight to me is not more than a few kb, because I want them to be interactive(not just a static image), but i'm not going to have so many of them that I need a huge jquery plugin, just something small.
Also: I'm trying to make it so it's responsive, and shrinks to fit a phones screen.
SVG sounds just like what you are looking for. You can use a library such as JQuery SVG or Raphael (based on Prototype.js) to make it easier.
Google Chart API is very solid and easy to use. Here is an example of a simple Line Chart
http://code.google.com/apis/ajax/playground/?type=visualization#line_chart
You can also Interact with the charts you create:
https://google-developers.appspot.com/chart/interactive/docs/basic_interactivity
https://google-developers.appspot.com/chart/interactive/docs/events
I don't know how lightweight you could possibly get to do what you want, for that kind of thing I would normally use flot.
If you are not planning any manipulation on the graphs. Use a PHP library called pChart
Check out Google Charts. It looks like the perfect thing. It doesn't use flash, so it's smaller than some, and it has tooltips. As a bonus, you can use live data on the web.
Hi I'm looking for a way to create a panorama view with a 360 degrees photo. I need a solution to do create something like QTVR. There is a lot flash based software out there (I'm trying to avoid that) and also some javascript/prototype/jquery solutions. But none of the solutions I've found have the behaviour I'm looking for. I want to eanable users to look around (just horizontal). Furniture objects on the pictures should react on mouseover, so that I might have multiple "layers" to distort. Is there a way to manipulate images in pure javascript or with jquery so, that it looks like they where bent cylindrical? Or does anyone know good libraries that support that kind of image manipulation? Might webgl be a good solution? I don't really know how to start. Is there anyone who could give me a hint. I'm just looking for a direction. google didn't bring me usable results.
Check out three.js
http://mrdoob.github.com/three.js/examples/webgl_panorama_equirectangular.html
Also, you could possibly do some of the image manipulation via canvas.
https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Pixel_manipulation_with_canvas
It might be easier (with canvas) to just have a fully processed panoramic image, and figure out which pixels represent your interactive object. Then listen for mouseovers on those pixels.
try out http://panorado.com/en/PanoradoJs.php
There you'll find an excellent HTML5/JS based Viewer.
There are lots of tool to do that. Have you tried www.vtility.net ? Im not sure if it had mouse over layering. But it was the only SEO friendly that I have found.
I am trying to develop a system that will render a preview of a what a product might look like with embossing.
In order to do this, I am essentially going to composite two images together. In order to do this correctly, I am building a system using mainly JavaScript that allows a background image to be chosen. Someone will then draw a quadrilateral on this image that represents the correct proportions of the composite image.
This image, which is rectangular, will be distorted to match the four coordinates that comprise this quadrilateral using Imagick.
The piece I'm a little hazy on is the JavaScript. It doesn't need to support multiple browsers, Webkit or FF is fine.
At a minimum, it should put a rectangular shape comprised of four points. These points can then be manipulated at will and a line would be drawn between the points to help the user visualize the effect.
This is a crude description, but the best I have. In a perfect world, I'd love to do something similar to this , but with more flexibility. http://jqueryui.com/demos/resizable/#aspect-ratio is also a good example of something similar to what I'm envisioning, but with less constrained transformations.
I've investigated Raphael.js, which looks promising too but I'm weary of reinventing the wheel.
Any thoughts? Am I missing any obvious JavaScript libraries/implementations that might be useful here?
EDIT: I ended up using Flash and this AS3 class: http://www.rubenswieringa.com/blog/distortimage
It was a pain, but I got it working. I'm leaving this up in case someone wants to opine on a javascript technique.
