How to display an object mesh continually update with the Labview 3D photo object

I have a stream of update permanently of 3D images that can be represented in a mesh (a film in 3D if you want). I want to display in the 3D image object so that whenever I acquire a new 3D image that it is displayed. Examples are rare, and I couldn't find anything that dealt with this particular issue.

Currently (in a FOR/loop WHILE) for each iteration I create an object of the scene, set the geometry as an object mesh newly created, set the texture and it wire eventually to the 3D image. This implementation seems a memory leak (Task Manager shows permanently increases the used memory and processing speed will eventually drop). I guess that's because I recreate the object for each iteration. Problem is, I can't find something that would let me release/delete the object once I'm done with the framework. All the examples I found only deal with the creation of the 3D object once and manipulating.

What is the appropriate way to code this?

You just need to use the "narrow" VI on reference photo 3D like this code below. It runs inside the loop.

Now, if you're dealing with the mesh, then you should use the set the mesh to change the points inside the loop and then just close the reference after the code is done. Look at this code below. The trick is to recover the object using Typecast (to more specific reference VI) reference.

Also, look at examples of shipping to:

C:\nivs_dev\2013\InstallTo\ProgramFiles\National Instruments\LabVIEW\examples\picture\3D Picture Control

and especially the with Meshes.vi.

  • Restrictions does not not after ISO put 10.0.1 update with the new iPhone 7

    Restrictions does not after ISO put 10.0.1 update with the new iPhone 7 any which option of ranking app I don't choose no changes are made.  All the patches?

    Thank you

    Hello Launcher,

    Thank you for bringing your question about Restrictions here in Apple Support communities. My understanding of your question is that you change the Restrictions, but no change is noticed. I tried the same on my iPhone 6 Plus running iOS 10 and noticed a similar situation. Please allow me the opportunity to explain how the Restrictions is designed to work. First, I put my limitations for applications, do not allow Apps and together 4 +, which basically means everything beyond 4 + will be blocked from buying. Then I went to the App Store and the first app that caught my attention was NCIS: hidden crimes. This app is rated 12 + and is definitely an application I would not want my toddler to help. It is that Restrictions come into play. When I type on NCIS: hidden Crimes, the Get option is grayed out. Restrictions does remove all apps, songs, books, etc. from view, but it will prevent the purchase, download, and install all applications rated above the setting you choose when you set up restrictions. It's the help article that discusses the Restrictions and prevent purchases: Use Restrictions in order to avoid buying on iPhone, iPad, or iPod touch.

    I checked on the restrictions help articles, and I understand where it can be a bit confusing. In the help article Use Restrictions on iPhone, iPad and iPod touch, it says "You can use Restrictions, also known as parental control, to block or limit specific applications and features on your iPhone, iPad or iPod touch." This means in fact that apps, features or services (rated above that helped you, or if you have turned off completely) can he no longer appears on the device if the restriction is activated and starts blocking them. I also tested this by activating Restrictions and turned the cursor for Safari to off. When I went back to the home screen, Safari doesn't show any more and I could no longer use it.

    I hope this helps to clarify how the Restrictions. If my understanding of the issue was not accurate to the issue that you are experiencing, I will be happy to pursue this issue with you. Please indicate exactly what you took measures, and what expectations you had or the some restrictions, applications, features, or services you are restricted. Thanks again and have a great rest of your day!

    Is this a known bug, and is there any fix for it?

    Thank you

    I have not tried running your code, but here are some possible solutions:

    1. There is a primitive to write the value of a control by index (added in ~ 2013). This is designed to be used others live too and should work like a local.
    2. You can send data using another way (like a queue, etc.).
    3. Use the Ctl Val.Set method.
    4. Do not use a chart. Use a chart and manage the buffer yourself. You can find some examples if you're looking for graph XY.

  • 1013 JDev how 2 display number on a specific attribute on the output text table?

    Page 1: I created a form of parameter with 7 top search criteria fields and table of results of search or a Table read-only ADF downstairs. The setting is based on the application of top link where each parameter is as the corresponding field in a table and works very well!

    For Page 2: I want the page looking at the same research, same parameter table of search results albums and even down with the addition of display also count on a particular area so that when someone enters data into the fields of setting up, he would always check the table and show the results of all fields, but in the last column do a count on this field (totally separate from the default number of records to search entire JDEV).

    Is it possible to create as a count or count (*) function at the level of the line of text out? I tried to create a view based on a Select sql statement a, b, c, d, count (e) table, group by a, b, c, d, e and when I dragg this object that contains this sql statement from the data control panel, it gives me the correct regulation of all areas, including the last column to display the number of records for this field , but together does never change based on what has been entered in the parameter, it is as if he is not yet connected to it. For ex: I want to display the number of all students within the setting of the East region, on the contrary it shows total number for all regions, not specific to East.

    Hello:

    I worked on a very simple application form ADF search against table Scott.emp in the Oracle database.
    Now I see what you mean. The idea is probably you shouldn't directly drag and drop control of your data: directly in your jspx as «ADF search form» Here are the steps:
    (1) create your entity object, the view object and I'm in the model layer; (You have already done this, you do not have entity and your view may come of TopLink request;)
    2) double-click the View object in your project of "model"; Add a connection variable: type Bind_deptno Number. It's read in a number of dept on the search engine;
    (3) change the SQL statement of the Emp View object on the same place as 2); WHERE Emp.Deptno = NVL (: Bind_deptno, Emp.Deptno) this indicates ADF if the binding variable is bound to a value
    then use this value, or if it is null, just ignore it. That's the tricky part;
    (4) create a new JSF called "Search.jsp', which will be the search engine;
    (5) from App Module, select EmpView1 (EmpView is updatable, EmpView1 is read-only, but it is not serious on the research plan), drag and drop the EmpView1 on your
    Search.jsp as an array of the ADF (not a search ADF form). This ADF table then displays the result of the research;
    (6) of the control Module of the App, go to EmpView1 data, drag and drop a "ExecuteWithParams" on your search engine like settings-> parameter ADF
    Form, this will tell ADF you want to set the variable binding as an executable looking for shape parameter.
    That's all! and you're good to go. Do the same for the other variable binding (you have 7 search criteria, so you have set 7 bind variable by using the same logic here.
    Good luck and don't forget to mark my answer as "correct" it to make me a few partitions.

    Best regards

    Sanchez.

    Double-click the validation button, to link Action property dialog will appear and then create a method of bean managed for the validation button.
    Then, add the following code to the method:

    public String saveButton_action() {}
    BindingContainer links = getBindings();
    OperationBinding operationBinding = bindings.getOperationBinding ("Commit");
    Object result = operationBinding.execute ();
    Note "!" operator has been removed from the default code.
    {if (OperationBinding.GetErrors (). IsEmpty())}
    FacesContext ctx = FacesContext.getCurrentInstance ();
    FacesMessage saveMsg is new FacesMessage ("saved successfully");.
    ctx.addMessage (null, saveMsg);
    }
    Returns a null value.
    }

    Then, restore the ActionListener value.

    I hope this helps.
