How to render point cloud data in browser with iTowns2

I am attempting to use iTowns2 (https://github.com/iTowns/itowns2) to visualize point cloud data in the browser. According to the README: "[iTowns'] first purpose was the visualisation of street view images and terrestrial lidar point cloud."
From this I glean that there should be instances of people using iTowns to visualize point cloud data somewhere online. I've been looking for days and I can't find an example of someone using iTowns2 to visualize point cloud data in the browser.
The example in the GH repo renders a globe in the browser but no point cloud. There is a iTowns/iTowns2-sample-data repo which has a bunch of point cloud data but no instructions on how to use the data or references to other resources.
Has anyone used this package to show point cloud data in the browser? Does anyone know an article or resource that demonstrates doing this with iTowns2? Does anyone know of a different library for rendering point cloud data with examples and/or better documentation?
Ideally I would be able to track down the source code for something like this: http://www.itowns-project.org/#demo

The documentation is quite ambiguous, and judgind by the Github issues it looks like the library is under heavy refactoring.
I took a quick look to this repo and realized that it is just using Potree for point cloud visualization:
http://potree.org/
So you can just use Potree directly. Wich is better documented.
In addition to this, it's quite trivial to set up your own point cloud visualizer using Three.js.
Just take a look at the Points object:
https://threejs.org/docs/#api/objects/Points
And this example:
https://github.com/mrdoob/three.js/blob/master/examples/webgl_buffergeometry_points.html
Three.js also includes some 3D format loaders, like ply:
https://github.com/mrdoob/three.js/blob/master/examples/webgl_loader_ply.html
If you are interested in using las files you might also want to look at:

Let's provide a early 2018 update! (source: I'm a maintainer)
iTowns now supports visualizing pointclouds directly. You can test it here: http://www.itowns-project.org/itowns/examples/pointcloud.html
If you want to test your own data, please visit http://www.itowns-project.org/itowns/examples/pointcloud.html?selector=1
We currently support results from PotreeConverter, and lopocs. We plan to add 3dtiles pointcloud format soon.
We indeed used potree for pointclouds before, but that was not ideal, a bit because we diverge on some technology/design choices, but mainly because using potree prevented us to tightly integrate pointcloud visualization in iTowns. For instance, iTowns stops its rendering loop when it has nothing to do (saves a lot of cpu), and potree does not. It also allows us to implement our own culling/SSE/network priority... heuristics.
Potree has currently better graphic post-treatments of pointclouds, although we also plan to add EDL and other improvements (occlusions for instance) soon. And of course, the advantage of iTowns is that it's not limited to pointclouds, but can display a variety of data type, from rasters to vectors, see the examples page and especially this example of a pointcloud on a globe.
But the main difference between these 2 projects is that Potree aims at being a standalone viewer (AFAIK), whereas iTowns is more a framework to implement your own app! Potree remains a big source of inspiration for us concerning pointclouds, big kudos to their maintainer :-)
(Btw, the github has moved to https://github.com/iTowns/itowns)

Create a 3D Bar Chart in AS3 and HTML5

I have to create a 3D Bar chart in Flash(AS3) and HTML5 which takes up input from a source and generates the graph, and they both should look alike, so what options do i have?? i mean are there any open libraries which will assist me to do it? (it should be Open Source)
Any help would be appreciated..
Thanks

I would imagine you would maybe want to start with something like Haxe to have a common framework that compiles to multiple languages. I'm not aware of any charting libraries that use Haxe (or are built using Haxe rather), or that are written to have a parallel between AS3 and HTML/JS. Instead of having to use something like Haxe or writing multiple versions in different languages and having to keep them up to date you could have a server side java handle generating the chart (returning bitmap data), the only issue with this is if you want interaction on the chart which puts you sort of in the same boat again.
Another option is to roll your own I did something like a "3d" bar chart while out camping one weekend (took two full charges of my laptop battery, but got it done without the internet).
http://www.shaunhusain.com/charts/
http://www.shaunhusain.com/charts/srcview/
I actually put it in that charts folder with the intention of circling back around to clean this up and do Pie/Line ones with similar 3d effect (not actually using any 3d).
There's some decent tutorials on writing your own charts, so long as they don't get too crazy with the design you could probably DIY. Plus whichever language you're weaker with you can just port to every time, so you start strong then learn how to convert.

Drawing SysML/UML diagrams in javascript

I have to write an application in javascript using the d3 graphics library to display SysML diagrams. I feel like most of this project is within my grasp but I have no idea how to approach one aspect of it.
Since the application will assume nothing about the complexity, size, or nesting of the diagram, hard-coding rules for how to arrange the blocks would be futile. I imagine significant study has gone into this kind of thing before but I am unaware of what it would fall under or where to look.
Also, does anyone know where to find examples of SysML diagrams in XML format? Any help is appreciated!

Since SysML is a UML2 profile, you might find jsUML2 a useful starting point for your attempts. Basically you could use the jsUML2 to draw the SysML diagram and then use the export function to produce the XML. NB: XMI is the standard for interchange between different tools.

3D development - Javascript/HTML5/CSS3?

I am working on this new project, wich is a new technology for me...
I'm working with Appcelerator Titanium, building this 3d application...
My applications suppose to be something like 3d Canvas...
I mean a ability to add objects to canvas (drag&drop),rotate them (3d),
and most important to rotate the whole Canvas(3d).
From checking the subject came with a lot of Plug-Ins and libraries:
Three.js,WebGl,HTML5 Canvas,CSS3...
The question is-Is anybody have an idea what is the best to use for
this mission?
Thanks!

Three.js makes it super-easy to make primitives and load pre-generated objects (typically from JSON data).
https://github.com/mrdoob/three.js/
Check out the examples at the bottom of the page, and note how little code is necessary to do anything. The only disadvantage is the overhead of a huge library like Three.js, along with the fact that it is still in its infancy and changing slightly by the month. Beyond that, there's not much advice I can give you as I have no idea what kinds of objects you plan to put in this canvas or what the goal if the project is.

Graphing on Rails 3 + dygraphs

I have a very large data set that I'd like to craft into a scaling, zoomable, panning graph that goes back over the course of a decade of data. It appears that the best solution for the job is dygraphs vs other options.
I'm not opposed to other options if any meet the requirements of very high interactivity, so if'n you got someth'n else, please share...
Notwithstanding, I have not found a solid example of using dygraphs with Rails 3 and would really appreciate seeing an example of how to tie this into a dataset very quickly or a link to an example.
Initially I just need to throw all of the content out into the graph to see how it works out and for some analysis, so nothing super fancy's needed.
**EDIT: Just found Highstock. Seems to be a perfect match. In that light I'd like to modify my request to perhaps some examples of utilizing Highstock in this context.

I can't point to any tutorials or lessons. I actually had this exact same problem a while ago, trying to do the exact same thing. My answer is that you just have to generate the HTML/dygraphs functions to plot your data.
In case you are still trying to figure this out, I have created rails app that will interactively let the user choose and plot data from any basic database schema, any database. I'm a total RoR noob, but it works pretty well and is made to be generic and dynamic, as well as add checkboxes and linear regressions to each plot. Its not finished, or fully documented yet but you may find it helpful.
I think you can access it this way:
git clone https://bitbucket.org/zachd1_618/rails-stocks.git
or just get in contact with me if you are for some reason really interested.
I've tested it on multiple databases and different schemas, and it easily handles 50k+ points across multiple graphs.

I see that Highstock is nice too, but you shouldn't have any problems in adapting Dygraphs to what you describe. I have not used it with Rails, but have good experiences with it on Django. The approach would be quite similar: Either you serve the dataset in a separate request, or you generate the dataset within the template layer. The latter is probably the slowest.
