I am new to the application development community and I am trying to customize an application created with ArcGIS Web AppBuilder to switch between 2D and 3D views. I have published 2 maps on my ArcGIS Portal, a 2D and a 3D from the same study area. The switch between the two views is easily done using ArcGIS API for JS, but this means that I will have to add all other widgets by myself. As I don't have the time to learn this from scratch, I have built an application using Web AppBuilder and have added one custom widget to it. However, I cannot make the widget work at all and I was wondering if my idea was even possible. Web AppBuilder only works with one map (2D OR 3D), which makes me doubt that I could insert the link to the 3D map at all in my Widget.js file. Did anyone try to do this?
Update on my issue: It seems that adding a custom widget to switch between views in WAB (developer's edition) is not currently possible.
I've received an answer on my post on the Esri Geonet forum: https://community.esri.com/thread/223878-s-it-possible-to-add-a-custom-widget-to-switch-between-2d-and-3d-view-in-web-appbuilder-developer-edition
"The reason is that WAB 2D currently uses the 3.x API and 3D uses 4.x. The sample in the 4.x samples can switch because it only uses the 4.x API. WAB has yep to solely uses the 4.x API due to all the features that are yet to be implemented. Once the APIs have reached parity then this will be possible."

I'm trying to develop a hybrid app which will deliver a range of simple teaching material to the user. I am planning on using Telerik App Builder in conjunction with Cordoba 3 to create the app. What I cannot decide is how best to package the actual content into the application. I'd like to achieve a separation of the content from the code, and just combine the two when building the delivery packages. (The content is being prepared by a subject matter expert.)
Is there a way I can use Cordova or Telerik AppBuilder to pre-populate a SQLite database as part of the app install process? Or am going about this in completely the wrong way? I have been researching this in the Telerik documentation but without success so far. If someone could point me towards a suitable example or even the correct places in the Telerik or Cordova docs I'd be very grateful!
I recently ran a techie webinar on the topic. The main idea is that you need a centralized system to host this content and this system needs to expose some kind of a service layer that will feed content to your app. To me this seems like a very growing market opportunity, but feels kinda the same as the web 1.0 days where all of us were trying to figure out how to feed cotnent to websites and everybody was building their own CMS in a way.
Telerik Backend Services provides an editing interface, so it can fit some requirements, but it's not a publishing system, plus you may not want to pay developer licenses to your back-end users or provide them with access. The premise of the webinar I am talking about was that we discussed how to integrate with another telerik product - Sitefinity to do this job for you instead. The first 20-25 minutes are an overview of the platfrom, so if you have seen it already, you can certainly jump to ~;0:25 to see the rest
http://www.sitefinity.com/campaigns/webinars/build-content-driven-mobile-apps
Now certainly it doesn't have to be Sitefinity or CMS for that matter, Sitefinity provides a bunch of App Builder related features that are handy, but you technically have a few options:
- Build your own applicaiton and back-end.
- Use any type of CMS or platform that will give your SMEs the back-end interface to publish and the service layer to expose to the app. In the webinar I also go through some neat tricks such as using push notifications upon publishing.
This way you get a clear separation of content and code - you can even get a separation of content structure and code, which is an idea i talk about in greater detail.
I hope this helps!

I want to build an application for mobile (ios,android) and Desktop (Windows) or Web.
The application will look like this: a 3D object which the user can play with the camera perspective around it and some menus.
What I need is to manipulate a 3D Object like torus or tube. by manipulate I mean: change materials and edit the object like a polygon. of course I also need menus and communication to a server.
*Optional: I am not sure if I need to load 3D model from a file.
What I don't understand is should I look for all in one solution or combine a cross platform framework with other libraries? Are Game engine suitable for this task?
My options so far:
Use Three.js with PhoneGap and write in java script
Use OGRE and write in C++ with some cross-platform framework that allow me to write in C++.
I never developed for mobile and I wonder about those cross-platform frameworks: does the application's size is big? does the application runs well? which obstacles should i have comparing writing separate applications for each platform?
Thank you for your help
Might want to look at libgdx .
I am developing a webapp which the most challenging aspect is the 3D model section. It also contains other things such as drag and drop and a sliding bar with arrows each side which the user can go through to select different items.
I have been looking into WebGL but it seems IE doesn't support it without using a plugin. This isn't ideal so I was wondering what other options I have.
Flash? Silverlight? Anything else?
Silverlight is WAY too rare to be used for any meaningful development, and ajax is simply not stunning enuogh. That leaves us with Flash, which in my opinion, is the best of the three options. Flash Player 11 introduces the new Stage3D API which can create pretty stunning 3D graphics. There are also many AS3 libraries for 3D rendering. I prefer Away3D
Just found this, which looks promising.

Edit: Disregard, seems the user has to download the executable for it to work.
at the moment flash is most popular plugin for 3D based web apps. which is cross browser, but no mobile browsers support :(
Many technologies and every one have his disatvantages
We’ve created an ASP.NET MVC 4.0 (Beta) web site with Visual Studio 2010. The web site will be used (or viewed) by standard browsers and by mobile devices.
Because of this, we’ve decided to use the new .mobile.cshtml pages offered in MVC 4.0. We basically copy/pasted all the Views and renamed them accordingly (with .mobile in them).
We are now ready to begin playing around the .mobile views…
Considering I have no past experience in mobile development, I’m curious to find out a few things. As an example, I’m trying to create a simple carousel that will gently slide and once it reaches the last image, it will start again at the first one.
I’m grasping at straws to find a simple example and in addition, I keep seeing/reading about Sencha Architect (which I’ve decided to download, only to realize it is some sort of IDE to develop mobile apps…correct me if I’m wrong).
In order to properly start, can anyone explain (or clarify) the differences between why should I use something like Sencha Architect versus using Visual Studio with jQuery Mobile?
Thanks.
You are indeed correct with sencha architect. Like Yourself I was puzzeled but it is designed to work alongside rather than with visual studio which I really have a hard time understanding
Due to senchas unique way in which it creates
Interface components. This doesn't mean you can't use sencha touch with mvc though in the same manner as jquery mobile. You can write your pages in mvc much the same way as you do now and use the applyto method in sencha to attach the sencha widget to it
As for the argument of sencha touch vs jquery mobile its down to you I guess
We are working on a Mind map based webapp as our final year college project. It will be a website where users will be able to create mind maps collaboratively. The user interface will be very similar to what https://bubbl.us/beta/ and hxxp://www.mindmeister.com/ have.
In a nutshell, the users will have access to whiteboard and drawing tools to create mind maps on a whiteboard. The changes made by one user will be visible to other session users. e.g. A session has three users A, B and C. If A changes mind map, it will be visible on whiteboards of B and C.
We were considering Flex, Openlaszlo few days ago but having limited time (about 3 months) for project completion, we binned those. For Flex we will have to learn Actionscript3 and for Openlaszlo there is no IDE support. So both of them won't be good choices.
We have shortlisted Silverlight and Vaadin frameworks as viable choices but we are confused as we don't have any experience with either of them. We need to take these points into consideration while selecting a framework:
Time frame for project - about 3 months, give or take 2-3 weeks
Learning curve for framework - should be easy (Very relative term indeed..In the context, we are familiar with VB6, PHP, Javascript and Core Java)
Necessary graphics related features supported - such as whiteboard, drag-drop widgets, animations(need not be fancy stuff) etc.
Availability of tutorials and good documentation
There are 2 open source mind mapping applications that can be useful for this webapp.
Silverlight - hxxp://silverdraw.codeplex.com/ (a webapp) - More like a POC design.
Java - hxxp://www.xmind.net/ (a desktop app) - Most of the mindmapping features we need are present. If we use Vaadin, we can re-use some code which is a huge plus point.
We are open to other suitable frameworks. Which framework would you choose?
P.S.: Excuse for obscure URLs'. New users are limited to only one hyperlink.
Disclaimer: I'm a member of the Vaadin Team, and do not know Silverlight very well.
I believe both Silverlight and Vaadin would be good candidates for your application, and for both the biggest challenge will be the client-side implementation of the visual mind-map component.
I took a quick look at XMind and it seems to be Swing based, so I'm afraid that the only way to re-use that would be to wrap the mapping component into an applet. You can easily do this with Vaadin, but it will require the Java plugin in the browser.
If you consider implementing the mindmap component without plugins, you have the following options:
Use the Vaadin core components (eg. the Tree, live example here) to visualize the mind map. Vaadin supports drag & drop, so this would be very fast to implement, and you would need to work with only server side Java stuff.
Create a HTML5 component with Vaadin integration for the mind-map. You can do this with the HTML5 canvas, and wrapping it in a Vaadin component is easy, but it'll require that you code the component with GWT. There are several examples on how to manipulate the canvas with Vaadin and GWT.
Create a SVG component with Vaadin integration for the mind-map. As far as I know SVG supports interactive stuff a little better than Canvas, and there are examples on how to interact with SVG using GWT and Vaadin. Note that the support for SVG is lacking especially with the older IE versions.
All of these options are feasible to implement within your timeframe (depending on what extra functionality you want). The first option is by far the easiest to do, but it might not be fancy enough for your requirements.
We have strived to make Vaadin as easy to learn and use as possible, and I daresay that our documentation is very good. In addition we have a very lively community filled with helpful experts. If you need more information on Vaadin just come over to our forums and we'll help you out.
You are kind off answering your own question. Use vaadin it will be a little extra work but then your saving huge amount of time on the mindmap coding.
