Adding 3D to a scene object Axes

I try to use the "Create 3D axis VI" (http://zone.ni.com/reference/en-XX/help/371361K-01/lvpict/create_3d_axis/) to add a set of axes to my scene of mesh object. The mesh changes with time (actually from measures) and must therefore be in a loop. Put the VI 3D axes in the loop works, but creates a horrible memory leak, as the VI creates new objects in each race. Do not put in the loop creates "1055 error to Invoke node; Possible reasons: LabVIEW: object reference is not valid. "error. Can someone please suggest a way around this?

In addition, I have need the sphere to create in the VI. This is because I couldn't add axes without wiring something to the Drawable of the invoke node entry.

Thank you!

Add the objects outside of the loop.  Take the exit of the 'Drawable Set', cast to a reference of mesh and he in the loop wire.  Then, in the loop, simply modify the data required for the primitive in each loop and call the method 'Redraw' the control of 3D image.  The 3D image is reference based, which means that the reference points object drawable to the REAL object in memory that is under development.

In addition, when you are not using the output of "Drawable Set" or "Add an item", you MUST tie a knot 'Close Reference' out there.

  • is it possible to apply the sort on the columns added to a dynamic display object?

    Hi all


    We use JDeveloper Studio Edition Version 12.1.3.0.0 and deployed on GlassFish Server Open Source Edition 3.1.2.2 (build 5) and connect to the SQLServer database.


    We have created a dynamic display object in the AM Impl, all objects in view columns are added dynamically.


    All lines are displayed correctly, but when sorting columns data disappear. (point of view are being refreshed, of course).

  • Adding a listener click scene

    Hi all

    I added an earpiece on stage to close a loader object when it is clicked on the stage. The problem is the click seems to affect the loader object for (basically when you click on the charger it calls the click function attached to the stage). Is this normal? I guess it's logical, but is possible to add a listener to the scene which excludes some items?

    Thank you

    events bubble in flash if yes, who expects this behavior.

    to prevent the propagation of the event, you can use:

    e.stopImmediatePropagation)

    in your handler for Chargers (where e is the event).

  • Adding mobile layout of entire objects breaks

    When I add an object (shape or image) that extends to the sides of the layout of my page layout condensesin the browser or window preview. Remove these items solves the problem. But I want to run some elements to the edge. No idea how to solve this problem?

    The site can be accessed at http://www.workshopdigital.com.au/Palomino . I also reproduced this problem with another test site.

    The question can be seen when viewing the site on an iphone.

    Your mobile site is very well on an iPhone. Looks like you figured it out.

    While adding a 100% width, you just need to make sure that the edges of the rectangle/text frame lines up on the grid of the bounding box and not extending beyond these lines otherwise could cause the layout to not fit the mobile screen completely while making the area gray to appear leading moving. In addition, you should consider optimizing images for mobile networks like the here a http://www.workshopdigital.com.au/palomino/images/main-2742x497.png> is almost 650 KB in size.

  • Adding a line to an object now changes the form...

    What the hell is happening?

    I apply a stroke to an object and shape change, radically!

    Also, I select a part of a path and use the keys for this boost over a little, but the selection does not move, the other part of the track don't! What gives?

    Herbiedriver,

    If this may be something related to snap to grid of pixels, you can select the entire document and untick finally align on the pixel grid in the Transform palette and uncheck also align new objects to the pixel grid in the options of the Launcher. It is crucial that the checkbox is disabled completely, not just a - which also count as ticked.

    It may be noted that even align with the pixel grid is cleared with all the selected objects, align new objects to the pixel grid is checked as the creation of new objects will result in these new objects being aligned, even when they are created from existing objects that can happen with Pathfinder operations.

    You can avoid the types of documents with the default (RGB for the web and other) or change the default value for such documents.

    Or you can try to disable the GPU performance by clicking on the icon of the rocket in the bar of the App, or on the top of the menu bar, deselect the box Performance GPU. You may also uncheck performance GPU in your preferences.

  • Adding new user defined Library objects

    Illustrator CS3 on Mac.

    Is there a way to ad a new color to a library of shades defined the user, or a new symbol for a user defined library of symbols. I have libraries of shades for all my customer accounts and sometimes a new color needs to be added and there are always modified as part of this library symbol. I always create a new library personalized with the existing and the new colors. It goes the same for symbols. It's a pain.

    Any help much appreciated. Thank you.

    Find your library file, open, and add a color and do a shade and save.

    You usually save this file in/Users/Username/Library/Application Support / Adobe / Adobe Illustrator CS #/ fr_FR/color chart

    you simply open the library (s) you want and add a shade and save the closed document and then load in the document you need in the future.

  • Unexpected behavior in the curve route 2 generated by script

    All,

    As part of a larger 'application', we generate a number of curves of time vs measurand of our test data.  We are now trying to add several additional graphs of this type, but this time, including signals (curves) on each of the additional graphics, and charts must be created exclusively by a script.  The results are shown in the attached file ("desired output_script generated 2-curve plot.jpg").  However, after you run the script attached ("of report generation Script_2 Curves.PDF"), it seems that there is no displayed curves on the graph resulting, as indicated in the attached file ("real output_script generated 2-curve intrigue, jpg").

    Most of the code to create the chart was captured using the method of 'ctrl-A' on the "Curve and definition of the axis" dialog box after you manually configure the desired graphic.  After the transfer of the captured code to the script, additional lines were added to create the various objects (axes, curves, etc.) and the new objects (since the final graph will be generated 'from') scratch.  I used this method before with great success.

    This problem seems similar to what I had already met (and published information on) trying to add a constant (horizontal line) of a measurand existing against time graph.  Because of this similarity and the resolution of the previous question, I added the PicDefByIdent = 1 directive in scripts, but the results of same behavior if this directive (and the definition of the associated "name-based" curve) is included.  In addition, PicUpdate is called at the end of the script.

    We use DIAdem 11.3 (with TDM Service Pack 1).

    Any assistance anyone can provide this number will be greatly appreciated.

    Kind regards

    Bill Evans

    720-988-3436.

    Bill,

    I'm looking into your question and he's looking for a little, but I have a few things to try now.

    First of all, once you run the script, could you try to refresh the screen to report? PicUpdate should take care of this, but it does not hurt to be excluded as a possibility.

    Secondly, I found this example on our site on the creation of a new chart and plotting to it: https://decibel.ni.com/content/docs/DOC-3994

    And one thing I notice from this example, it's that they give the channels with D2CChnXName and D2CChnYName rather than D2ChnX and D2ChnY, so here's an example of what their definitions of strings like:

    D2CChnXName = EXAMPLE/Time"."
    D2CChnYName = ' EXAMPLE/speed '.

    I suggest to change this in your own code and see if it makes a difference. It is possible that setting the variables 'name' instead of just the X and the Y will solve the problem.

    If these steps do not resolve the problem, do not hesitate to post back and I'll be happy to work on the issue more in depth and help that understand you why this does not work.

  • Hide objects outside the scene

    I recently downloaded a sample FLA file and I see the scene is FIXED on the upper left side of the screen flash and objects outside of the scene does not appear on the screen (like a mask, but there is no layer mask).

    When I create a new file of the scene appears in the middle of the screen and outside the scene objects are not hidden.

  • Adding Advanced action causes objects to not appear

    In Cp5.5 I have a strange situation. I created a questionnaire and everything worked very well. At one point, I noticed that on questions quiz that some just objects are not displayed, or rather, they display very faded, almost invisible. It's just about certain objects:

    • It concerns all the text captions and images added by me (no not objects standard quiz)
    • It's the only objects that appear either not 0 seconds on the timeline, or have "Fade In" effect. The objects that are on the chronology of 0 seconds and not including any transition normally appear
    • It can be easily fixed by removing the Action advanced in "on entry. The tip Action can contain anything or even be empty, it is not serious (currently it contains just "keep"). The fact that "on entrance" suggested Action is the cause of the problem.

    Copy of the slides to a new project does not help, bug moves with the slide. I tried to deconstruct the slide to identify the problem and remove almost everything, but the error is still there. The original quiz must have images that appear in the calendar after 1 second, and of course the quiz must Action Advanced enter. It seems that the only way is to recreate from scratch (no guarantee will not repeat the problem).

    Does anyone have an idea what to do to make it work?

    http://DL.dropbox.com/u/86167389/project.zip

    It seems that your advanced Actions has been corrupted somehow.

    When I removed both of your advanced Actions and implement new, the problem disappeared.

  • Draw two object with sceneMesh

    Hello

    I need two draw two independent vertices in the same 3D graphic models, I put the summits and index them in two different application SceneMesh and I tried to display the model in the same 3D graph but it is not possible. So does anyone have an idea how I can do this and be able to control the two items with a camera?

    Thank you in advance.

    Omar

    Hi Omar,.

    This link shows 3D how two objects can be added to the same scene. It also shows how to use object translations can be used to move objects around the stage that can be used to create the illusion of a camera moving objects over the stage window. I used these same methods of implementation when creating a ball game and palette in 3D. Translations can be performed on individual objects too, so you can allow objects change their relative position to each other.

    Is that what you had in mind?

  • Add an object 3d without parent/child relationship.

    Hello

    I have a scene of 3d picture control, I have two objects in there, but when I created the scene I had to use the add object invoke node objects in the scene, so there is a parent/child relationship between the objects, which means that if I move the parent, I also move the child object. Is there a way to create a scene with several objects without the parent/child relationship.

    Thank you.

  • object null reference problem

    Hello all and first of all thanks for reading,

    My problem is this, at my request, I have a textfield located at,.

    This.wholesite_mc.explan_mc.e_mc.cap_talk_txt. Text

    now, normally I can access this text and change it whenever I like using the

    MovieClip (parent).e_mc.cap_talk_txt.text = ""

    and so on

    problem is that I have a help file, which is located in the library and added using addchild().

    When you click on the help icon this function runs

    function helpvisit (): void {}
    btn_help1_mc. Visible = false;
    btn_help1_mc.btn_back_mc.mouseChildren = false;
    btn_help1_mc.btn_replay_mc.mouseChildren = false;
    btn_help1_mc.btn_back_mc.buttonMode = true;
    btn_help1_mc.btn_replay_mc.buttonMode = true;
    btn_help1_mc.btn_back_mc.addEventListener (MouseEvent.CLICK, bclicked);
    btn_help1_mc.btn_replay_mc.addEventListener (MouseEvent.CLICK, rclicked);
    btn_help1_mc.btn_back_mc.addEventListener (MouseEvent.MOUSE_OUT, fighting);
    btn_help1_mc.btn_back_mc.addEventListener (MouseEvent.MOUSE_OVER, bover);
    btn_help1_mc.btn_replay_mc.addEventListener (MouseEvent.MOUSE_OUT, rout);
    btn_help1_mc.btn_replay_mc.addEventListener (MouseEvent.MOUSE_OVER, rover);

    MovieClip (this.parent).e_mc.menubar_full_mc.visible = false;
    jigh10_mc.gotoAndPlay (2);
    MovieClip (this.parent).e_mc.cap_talk_txt.text = "";
    MovieClip (this.parent).e_mc.cap_talk_txt.text = "allows to count the bombs on this piece together!"
    }

    fine so far

    inside the MC aid, there is a clip called jigh10_mc

    and on some images in this example, 247

    I have the following

    MovieClip (parent.parent).e_mc.cap_talk_txt.text = "number of bombs on this piece is ten, you see where it fits on the left?

    Now whenever I run it, everything's fine except that I get an error in the output window saying

    TypeError: Error #1009: cannot access a property or method of a null object reference.

    at::jigh10_mc_92/frame247() [wholesite3_fla.jigh10_mc_92::frame247:1] wholesite3_fla

    I would appreciate any information, that you may have on how to solve this problem.

    ive tried to use functions and counters in jigh10_mc that point to the parent who then replaces the text but I still got the error

    the code seems to run even if I'm not in the help section, as lightning will complain of the same mistake while I'm game section

    Thanks in advance

    fonzio

    When you 'addChild (helpFile)' you can try:

    helpFile.addEventListener (Event.ADDED_TO_STAGE, added);

    added function (e: Event) {}

    trace ("I just added myself to the scene and now I can meet the functions")

    helpFile.removeEventListener (Event.ADDED_TO_STAGE, added);

    do other things now

  • Strange property undefined object

    I created a clip and exported if ACE, naming the class "Tank." The clip has a couple of labels of image with a few photos inside on each label.

    The SWF file opens, it gets added dynamically to the scene as follows:

    var charMC:MovieClip = new Char();
    addChild (charMC);
    charMC.x = 164;
    charMC.y = 624;

    It works fine without error.

    However, further down I have a function that will call this clip and move it into a different image. As follows:

    function someFunction (): void

    {

    a few things

    charMC.gotoAndPlay ("start");

    }

    This does not work, and I get the error "Property not set of charMC access."

    Note This function has not yet been called yet, I get the error when compile the swf file. It makes no sense to me. What I am doing wrong? It seems that the variable/object is in scope, as it has already been set and even added to the scene.

    Where are you declaring and adding the clip?

    If var charMC:MovieClip = new Char();

    is inside a function, then it is not available everywhere, but inside this function.
