The lack of support of Open GL in Java FX 2 forces us to use Swing?

Hello

We are about to begin the development of a major UI in Java. Of course, we prefer this implementation in Java FX 2, rather than Swing. However, we need return 3D models heavy (generated from several CAD files) with superposition of 3D point clouds with ~ 400 K points. We already have an implementation of Swing that supports this, based on the JOGL API. What I understand, there is no support for JOGL or similar OpenGL wrapper Java FX 2. Instead, Java FX 2 seems to aim at a high level 3D API. Based on previous attempts to use similar high-level API in .NET (for example WPF 3D) world, high-level 3D API usually are not suitable when working with complex 3D models and.

Therefore, I would like to ask for suggestions on what to do here. Do we have to develop our new Interface in Swing because of this? Or the JavaFX announced SwingNode can be used to encapsulate such a complex Swing component? If so, how performance would suffer from the packaging of JavaFX? If the SwingNode does not resolve the problem and so we need to implement the main application in the swing, consider still implement the subviews non - 3D with Java FX 2 or must go us to Swing all the way? Our developer group has experience of the swing, but no Java FX. Yet he felt no good start the development of a new user interface - what we maintain for many years from now - using an application framework obsolete. We are about to decide our way forward here and would appreciate any thoughts on this topic.

Thank you

See this StackOverflow question: How to use OpenGL in JavaFX?

It seems that the best answer for you is the addition of a node OpenGL JavaFX.

An OpenGL node not yet added to the JavaFX platform.

Like you have a team of people experienced in 3D development and Java and all corresponding JavaFX code is open source, I encourage you to consider creating an OpenGL or working with Oracle to create node one and (if you're inclined) contributing to the development of back to the JavaFX code base.  If you are interested in this, contact the openjfx-dev mailing list.

> Don't we need to develop our new Interface in Swing because of this?

I don't think so.

> Or the JavaFX announced SwingNode can be used to encapsulate such a complex Swing component?

I don't know, but apparently not quite the right approach for me.

It seems that a dedicated OpenGL rendering node would be a better fit, as long as you don't need other functions of Swing in your SwingNode.

> If Yes, how performance would suffer from the packaging of JavaFX?

I think that if you had a JavaFX node that was a Swing node that has treated OpenGL performance would be probably worse than a knot of JavaFX managed OpenGL directly.

> If the SwingNode does not resolve the problem and so we need to implement the main application in the swing, consider still implement the subviews non - 3D with Java FX 2 or must go us to Swing all the way?

Of either way would work, but I do not recommend mixing technology for your application, unless you have to.

There are a few considerations with mixture of JavaFX and Swing:

1 swing widgets a different aspect of the JavaFX widgets (and it's not trivial to make it look the same).

2. you get two boxes to tools and then mentally switch between them during the development (it's all just annoying).

3. He must be (very) attention to the problems of thread as each toolkit has its own main thread.

4. There are some bugs mix JavaFX and Swing (Search JFXPanel in the incident manager) that would not just happen if you weren't mix libraries (most of these bugs have been addressed, but some are exceptional).

5. the Swing features will not change, he's good at what he does, but he won't change and improve.

He wasn't there (very) experimental by merging the application threads to JavaFX and Swing, making it a model of combined programming a little more pleasant to deal with, but remains to be seen if this experimental feature becomes a default value for both platforms.

Unless you want to reuse existing extended Swing libraries (like NetBeans RCP), a pure JavaFX application seems better (as long as the node OpenGL can be developed).

> Our developer group has experience of the swing, but no Java FX.

There are similarities, prior knowledge of the Swing are an advantage, but there are a lot of new things to learn in JavaFX (and a few things to unlearn the likely swing).

My 2 c... good luck with your project.

  • Why the lack of support for iTunes store failures?

    As much as I love Apple products, being is not only an owner of an iMac, MacBook Pro, iPhone and iPad, but also a shareholder, I wonder why the company is either not willing to admit when there are interruptions in the iTunes store, or whether they are simply end in recognizing him on their map of the system state.

    When I called today (September 21, 2016 at about 11 p.m. EDT) to report the error, I was getting ("your application is temporarily unable to process'), when I tried to manage my subscriptions and activated the devices, Apple tech support person acknowledged that he also could not also see the same sections for himself under my account management. Yet, when he passed me along a representative of iTunes, the rep said that he knew no problems or outages at all. Yet, the "Downdetector" site said interruptions common to iTunes through the country. I live in Washington, D.C.

    Except for problems with the iTunes store, Apple has provided me with support superb customer whenever I called to solve the problem with my devices (iPhone, iPad, iMac and MacBook Pro). I'm frankly puzzled why they aren't equally useful when I called to solve problems of access while trying to access my account in the iTunes store.

    You know you talk to other users on these forums of users, and Apple are not here. And speculation on the policies or procedures of Apple is not allowed on these forums. If you wish to contact Apple use the "contact us" at the bottom right of each page here.

  • Official word on the lack of support for Ubuntu 9.10 as host?

    Is there any official word on why Ubuntu 9.10 is not supported as a host for Workstation 6.5 or 7 Workstation? Ubuntu 9.10 incorporates many features that are very useful, but I can't upgrade to it until I can be sure that VMware Workstation is supported in this regard.

    Looks like VMware Workstation 7.01 was released Friday and now includes support for Ubuntu 9.10 as a host and guest.

    My iCloud and shared calendars has stopped working in MS Outlook today.  They worked yesterday.  Now, I get the error message "cannot open this series of records.  The information store cannot be opened?  I tried the fix standard support.

    Same thing here.  Looks like Windows did an automatic update during the night, and now nothing iCloud associated work (calendars, contacts, etc.)

    I also noticed that the error message: "could not load file or Assembly ' MOM." Implementation ' or one of its dependencies.  The system cannot find the specified file. "It started after restarting the Windows Update as well.  I imagine that the two are related in the same problem to iCloud.

  • Disable the Passport to the supplier portal Support does not

    I have an existing application for the sale which has been marked as being supported for all devices BB10.  When the passport was released, the current version has been updated automatically show their support for the Passport (which is a hell of an assumption to make, but not the topic of the post)

    As the app is not supported for the Passport, I opened a session in the supplier portal and disabled support for the passport of the current version.  Connection again today, I see that it is still the case.  All the changes you want devices are controlled and passport is not.

    Screen grap of audit this Passport is disabled: http://tinypic.com/r/34gscw9/8

    However, I have just confirmed that in AppWorld, this application is available for the Passport.  Downloaded and installed smoothly (appears broken due to lack of support of passport)

    Did I miss something?  Users are complaining it is understandable that the app is broken for passport and this is wrong our rating

    Thanks in advance

    Hi people,

    A few things;

    (a) before a new device being available in the provider portal (and more if you launch to the public) we send all the BlackBerry World suppliers and let them know the new device, to provide links to resources, etc.  We also note that if your application supports a similar device (and not fail all of the tests made in-house), we will add the new device to your list of supported devices.  The realization of this is not ideal for some/many publishers, we also provide a link where you can opt-out of this process; allowing you to take your time and add the new device on your own schedule.

    (b) If a new device has already been added to the list of devices supported for your applications through the process described above, and that you want to remove, you will need to check your releases which have previously supported the similar device.  In the case of the passport for BlackBerry, you will need to check any release that supports the Q10 BlackBerry and BlackBerry passport to remove from the list of supported devices.

    Hope this helps to clarify.
