Pickpoint isn't hitting objects in the 3D scene

Hi all

I have a 3D graphics area on which I draw and manipulate several cubes. I'm trying to use pickpoint to allow the user to interactively click on objects and reproduced the steps in https://decibel.ni.com/content/docs/DOC-4958, which is remarkably similar to my request. Despite this, hit pickpoint always returns false.  Does anyone have any ideas why this could happen, i.e. pickpoint uses a different coordinate system or depends on the rotation/translation scene?

Thank you!

Well, after some time to play, I found the problem. Although it doesn't throw any errors if unwired, PickPoint terminal must be connected to something for the node invoke successfully to find a 3D object.

Don't know why, but I hope this helps someone somewhere down the line.

  • Add/Remove objects of the 3D scene programatically (or show/hide)

    I have a project I'm working on where we need to somehow add/remove objects in a 3D scene but without major lag.  Basically I have a set of objects in the real world I am reproducing in a 3D scene by loading 6 STL files.  I want to display only one of these items at a time.  When the currently displayed object is no longer present I want to quickly view another.

    I tried the subject 'remove' invoke the node without success.  I also tried a few other techniques that people have posted deal with transparency, but without a bit of luck.  It seems to me to recreate the scene when objects change is not an appropriate solution, because it seems to be a long process.

    I was wondering if there is someone who has done this or something similar in Labview.

    These links are for images.  Not for 3D objects.  I had this work with the Object.Remove method.  The main thing to keep in mind is to know what items are currently displayed in places and do not attempt to apply transformations, etc to objects that have been deleted.

  • Hit testing objects in the table problem

    Hey guys, thank you very much in advance for any comments.  These forums are a great help.

    I have a serious problem with a loop in a table. I'm trying to hitTestObject each MC in a table against all other MC in this table.   That part works.

    The problem is that in my statement of hitTestObject, so obviously examines only 2 items at a time.  When touch 2 MC, I put a property called 'Touch' to true.  The problem is they are moving MCs and at one point touching only 2 / 3.  What is happening is:

    The loop runs once as the test Array [0] and table [1].  Say that those who are affected.  She sets their properties 'Touch' true (it's what I want).  THEN it works again test Array [1] and table [2] and finds that they are NOT overlapping.  It this process it defines two of their properties 'Touch' to false, EVEN IF one of them may overlap a different array object.

    I want to individual, set the property to "Touch" for each object in the table.  Currently, these properties are getting crushed even if 2 / 3 objects are superimposed in fact.

    That makes sense?  Essentially the "else" statement is too often called because certain combinations of array objects are not touch, but others are.

    -----------------------CODE BELOW-----------------------

    stage.addEventListener (Event.ENTER_FRAME, hitTestBalls);

    function hitTestBalls(e:Event) {}

    for (var m1:int = 0; m1 < MonsterArray.length; m1 ++) {}

    for (var m2:int = m1 + 1; m2 < MonsterArray.length; m2 ++) {}

    {if (MonsterArray [M1] .hitTestObject (MonsterArray [m2]))}

    MonsterArray [m2]. Touch = true;

    MonsterArray [m1]. Touch = true;

    trace (MonsterArray [m1]. The touching, MonsterArray [m2]. Touch);

    trace (M1, m2);

    break?

    } else {}

    trace (M1, m2);

    trace ("NotTouching");

    MonsterArray [m1]. Touch = false; MonsterArray [m2]. Touch = false;

    }

    }

    }

    While waiting for a response, here's something to consider.  You don't want to affect the Touching false at any time after that you start the analysis, only front...

    function hitTestBalls(e:Event) {}

    first put all wrong

    for (var m0:int = 0; m0< monsterarray.length;="">

    MonsterArray [m0]. Touch = false;

    }

    now test for overlapping - this way you don't overwrite anything with fake

    for (var m1:int = 0; m1< monsterarray.length;="">

    for (var m2:int = m1 + 1; m2)< monsterarray.length;="" m2++)="">

    {if (MonsterArray [M1] .hitTestObject (MonsterArray [m2]))}

    MonsterArray [m2]. Touch = true;

    MonsterArray [m1]. Touch = true;

    }

    }

    }

    }

    And if there be oinky be a pair that overlap as you say, you can add a breakdown; orders to end a loop when a hit is detected.

  • DPS: Judge to use the parameter Raster or vector in the States of the objects when the majority of the page is a photo. What is the best setting for the overall performance?

    I am trying to decide whether to use the parameter Raster or vector in the States of the object when the majority of the screen is a picture (with a modest but important legend for children to read). The legend certainly makes it look more net as vector. But does the photo! The raster setting seems to make the lower-res images in comparison. In my first edition of my application, I thought that raster would be the best setting when the photo was the subject dominating the page. But now, after seeing how strong he looks like vector, (but with almost a refresh of the unacceptable time. Perhaps better on the latest iPad. Most of my readers/students in class will use iPad 2 s, which has a slower processor). I wonder if I should go through the trouble of changing States of photo objects that have the type as well to the vector. It doesn't seem to be as sensitive to a re - draw on the iPad 2 (non-retine)

    Is Filesize hit if I make about 1200 on these objects range from Raster to vector? (It is a huge, highly interactive history book, so I'm curious if acutally go to vector on these photos would reduce the size of the file) What is the best setting for the overall performance?

    I see the freeks screen outside for a bit if you try to pinch and zoom in a vector object (photo) vs raster. Which is disappointing. Does slow down load time/refreshment in frame, which is a little less. I also found that the drop shadows really bad that redraws effect in vector, almost vibrating in a slide show, for example. Thus, in cases where I need shadows, I'm sticking with Raster.

    All tips go ahead?

  • Impossible to move objects with the Selection tool

    So I just installed Illustrator CC, I have now on a trial license.  An hour ago, Illustrator suddenly began to refuse to move objects, while I'm in the selection tool.  I can move objects in the free transform.  I use shortcut keys a lot, so it's really slow me down.  I hit 'V' to click on and then move an object, and then it won't move. I get the error sound, but no dialog box appears to explain the error.

    Because I'm about to bite the bullet and start paying a hefty monthly fee for this program, at my trial runs out, that's enough aggravating circumstances.  Anyone has any ideas what can cause this?

    Looks like there could be a hidden modal dialog open. Hit the ESC key does nothing to release the objects?

  • create the object without the instance name

    Hello

    This is the problem, I have hero shoot bullets and because of that I can't give the objects an instance names and I want to check if the object on the stage or not and it's easy when

    I do var ball: BALL = new BULLET

    If {(bullet.stage)

    addChild (bullet)

    ...

    }

    but the problem only when I love it

    addChild (new BULLET())

    I know that flash to give a name, but how do I check their names?

    if(???. stade)

    Thank you

    Using a table simply to instantiate, then you can add to what you need.

    var balls: Array = new Array();

    Then, when you add a new bullet you can push in the table.

    Bullets.push (new BULLET());

    and if you need to go through them to test if they hit their target or if they should be deleted or whatever, you can loop through them, testing each during his turn in the loop.  If you would like to be removed it is usually better to go back across the table so that you do not skip any.  When you go forward through a table and remove items, the rest all shift down an index to fill the empty space, which means that it is possible to pass on a right after the one you deleted.

  • Deleting objects in the scene

    Hi all

    I have a few items on my stage, I uninstall applications with RemoveChild(). The items appear, however, as indicated in LiveDocs, the question is not destroyed. This means that links/headphones created by this object still exist and create errors (specifically, I'm ' the supplied DisplayObject must be a child of the ')
    "" "appellant"). "

    LiveDocs mentions that if I actually want to delete an object in the scene entirely, I have to use the 'delete' operator, but for the life of me, I can't find any documentation about the existence of such an operator. Any advice would be much appreciated.

  • Smooth against a move sharp objects on the screen

    Hello

    I have a number of applications that show the following behavior: when I click on an object on the display on the screen, the object moves * gently * to its position to another, predetermined by the application, position.

    I see this problem on my iMac.

    When I run the same applications on my MacBook Air the moving of objects from home position in the end still happens but in a * sudden * way - i.e. the object jumps abruptly starting position for the finals. The sweetness of the movement I see on the iMac is no longer exists.

    I love soft travel.

    Applications do not provide any parameter to control the way objects move (gently or brutally), I guess it is somehow controlled by the operating system. A parameter is defined differently on the iMac and the MacBook Air.

    (Both machines run El Capitan 10.11.6)

    Someone has an idea of what could be this setting? Or in any other way, I can have a good moving objects on the MacBook Air?

    Thanks in advance.

    FWIW, I do not know why your etrecheck report has been deleted, but you try to run applications on a 4 GB machine too. You should limit the number of objects, connect, and the number of programs you are running at the same time.

  • HP50g: HP50g - hot to check if the object of the stack is a number?

    How to check if an object on the stack is a number or another type of data? There seems to be no any function to check on 50g.

    50 g advanced users to see, page 1-13:

    "The order TYPE ([left SHIFT] PRG-> TEST-> NXT-> TYPE) accepts any object as argument and returns the number that identifies the type of this object." For example, 'HELLO' TYPE returns 2, the value of a string object. See table of object types in Chapter 3, in the command TYPE, to find objects of calculator and corresponding type numbers.

    Generally want to DUP the object to the level of the stack 1 first of all, because likely you want to do something with it, after checking his type.  The following RPL program checks the type of the object in level 1 of the pile and adds a string to the stack indicating its type.  Only some of the possible types are checked and a generic "something else" translates to others:

    «
    TYPE OF DUP
    CASE
    DUP 0 == THEN DROP 'real number' END
    DUP 1 == THEN DROP "complex number" END
    DUP 2 == THEN DROP 'chain' END
    DUP 3 == THEN DROP "real array" END
    DUP 5 is THEN DROP 'list' END
    DROP "something else"

  • How do I put FF so hit enter in the address bar refreshes a page if it is already loaded?

    Currently FF do not reload a Web page if you re - enter in the address bar.

    For example, go to your address bar right now. Don't change anything and press ENTER. Note that nothing happens? Even if there was new data on the page, it would not show upward. You must hit refresh on the page refresh in fact.
    EDIT: Good so it was a bad example... because it refreshes rofl. I can't say the same thing to happen for most of the other good sites.

  • 5.6 pages move the object to the background?

    Near as I can tell, there is no way to float an object behind the text in a Pages 5,6 word-processing file.

    I can place the rectangle, select it, but "send to back" do not place behind the text.

    Change the implementation of 'Stay on the Page' or 'Move with the text' does not work.

    I can't believe they have eliminated this option in the recent upgrade, but hope that they were hiding somewhere that I have not watched.

    Someone knows how to do this? (Outside of return to an earlier version of Pages.)

    Photo:

    Using the option "master article" seems wrong and a bit stupid.

    Help?

    What you have discovered is the trade-off between the use of object moving to Section Master in v5.6 Pages, or by using a real word processing in Pages ' 09 v4.3 (below) that allows to define simply object to the background (selectable or not) and he remains behind the text.

  • ActiveX - Word - casting of the objects to the variants

    Hello

    I'm just getting used to the use of Active X to automate the tasks of MS Office. I have the full suite and report generation tool does some things, but there are many others that I have and I give X a go Active (that's basically what NOR do anyway).

    I have problems with some of the methods they have a variant of entry type, but no one tells me what is the format of the Variant. For example, I give you this VI which seems to add a caption to an image. I see the following documentation from Microsoft, which tells me that:

    Documentation of the method

    Label
    Type: System.Object

    Required object. The legend label must be inserted. It may be one of the WdCaptionLabelID constants.

    Title
    Type: System.Object

    Optional object. String to be inserted immediately after the caption (ignored if TitleAutoText is specified).

    http://msdn.Microsoft.com/en-us/library/Microsoft.Office.Interop.Word.range.InsertCaption%28V=Office...

    -So, I should get my variant such as "System.Object" (?). I could probably assume that the title is just a simple string, but where would know that officially? My guess will fail eventually.

    Enum for type of legend:

    http://msdn.Microsoft.com/en-us/library/Microsoft.Office.Interop.Word.WdCaptionLabelID%28V=Office.15...

    -J' tried casting as a string and a number, or work (I guess an enum is a number, I tried 0,1,2)

    Any help would be appreciated, even if this can be more Microsoft is not to document their structure of objects that the problem of NOR, we are working towards the same goal! It is possible that there is another mistake as to why this program does not work, but I still need the General method...

    Note that you must have an input file specified to make the program work.

    COM Interop in LabVIEW execution is tedious for a number of reasons - mainly because of the architectural design of many COM components. Their well-designed components are loosely coupled, but this often means a lot of calls on many objects - many of whom often optional parameters. My suggestion is to use a wrapping to LabVIEW .net is necessary. It is not that it is not possible to apply directly in LabVIEW (obviously), but you need a lot of infrastructure in your code to make sure that you don't lose that same coupling or, more importantly still, readability in your own extension of LabVIEW.

    In your scenario, I would ask myself: is this interface that I am building a long-term solution or a code that I am likely to change often? If Yes, then you could encapsulate COM Interop calls, and actually create a façade allowing the final user (eg. LabVIEW) functionality you need via an interface determined, without exposing the interchangeable parts (COM Interop). However, you must be comfortable said creation .net assembly that can be intimidating if you don't have the experience.

    http://en.Wikipedia.org/wiki/Facade_pattern

    As future support goes - it's a really, really good thing that .net helps keep these old technologies going. Long term support becomes a growing concern for these markets (read - more commercial rather than consumer solutions) and there are millions of apps out there running currently running one of these technologies. It's one of the reasons why I have recommended to you than a façade may be the best solution in the long term - there is always a desktop API. A front will always provide the same interface, whatever it is, if the calling code is not affected when the fact of the way that you interface API.

    PS: Windows 8 exposes the WinRT Basic programming framework, which is based mainly on the... COM I don't see not its predecessor going anywhere for many years yet.
