How to create 3D webpage like link??
And give some examples like this type.
You need the three.js, and the three.js github link
three.js
JavaScript 3D library
The aim of the project is to create an easy to use, lightweight, 3D library. The library provides , , CSS3D and WebGL renderers.

I would like to know how I can go from a 3d model to a moveable in browser model. An example of this would be the roblox website. If you go to any player profile there is a character model that you can move around. My model has a .obj format. Would this format be compatible with the technology roblox uses?
Export your model in Maya to a wavefront(.obj) file. Then you could use a library like three.js, along with this script to load and view .obj files within the browser
obj to three.js JSON
Programming the moveable camera can also be done using the library. If you want to use the default formats, it will be tricky as you may need to write the parser yourself if there isn't one and the spec is freely available.
Just wondering if anyone can guide me into how this site was built: https://tylko.com/shelf/bookshelves/
I've seen fabric.js in use, but not sure how to go from there. Is there any platforms or services that would assist in creating this or it's a heavy custom-build project?
Thanks

This was built using a technology called WebGL
Based on your question, I understand that you are new to the field of 3D graphics, so I would highly recommend a higher level called 'Three.js' https://threejs.org
I recommend this because using WebGL from scratch is a very daunting experience, while Three.js is simply to use by comparison.

I know that Adobe 3D pdf support JavaScript. So, I have JavaScript code in Three.js for 3D models in 3D world.
Is it possible to have same (or similar) code in 3D pdf?
I mean, I load 3D models, and do things with 3D models and have that all in 3D pdf?
What do I have to have to have this?
Can I create scene with Adobe API?
Is it free, Adobe API?
You can add JavaSCript to a 3D Annotation using Adobe Acrobat manually or just about any PDF library tool that supports Rich Media Annotations or will allow you to access objects at the COS dictionary level. I can advise better if you can tell me what programming languages you are most proficient at. One thing to note is that there is no physics engine or collision detection in the Acrobat JavaScript for 3D API, you'd need to add that yourself... though it is certainly possible.
Does webGL contain push/popMatrix? and if not, how would I go about recreating them?
No, WebGL is based off of OpenGL ES 2.0, so there is no built in matrix management or fixed function pipeline. The model view and projection matrices need to be completely managed in your own code and passed to shaders at draw time. You really don't need push and pop matrix if you are using a scene graph or some kind of other similar scene management system. All you really need is a good matrix and vector math library.
If you are still set on using push and pop matrix, you could simply use an array of matrices, and write functions like push and pop that simply save your current matrix into the array and push or pop the index down.
I would get the OpenGL ES 2.0 programming guide if you need more help with transitioning to WebGL. The book's website here: http://opengles-book.com/ contains a download link to some source code with demos for a variety of platforms and languages including WebGL. It also contains a decent math library if you need it.
From what I see here and there, there is no native support but you can easily build such a stack with an Array.
I want to write chess in JavaScript but I am pretty new to JavaScript. Can somebody tell me good 2d library for JavaScript if exists ? Is there possible to write 3d objects with JavaScript ? Any advice is helpful
You should take a look at Raphaël and processing.js.
The processing.js reference lists a few 3d primitives so you can render 3d objects, at least in a limited manner.
Re: 3D objects in JS, Check out three.js for an excellent 3d library. It supports WebGL, Canvas, SVG rendering (WebGL being significantly faster in browser that support it).
Get a new browser if necessary (e.g. chrome dev build) and check out some of the webgl demos.
