Model pvz sequence binding at runtime

[RolandRaytchev]

So according to the subject here I want to add some points, which could be helpful, I hope.

- I suspect that the most stable sequences are generated with Creo Illustrate 3.0 and 3.1. Also 4.0 should work.

-When we want to use dynamic pvi  sequences in the HoloLens  we have to extract the .pvi file from the .pvz and upload the pvi sequences file  explicitly in the Studio resource folder. So here an example: 

So in the code below we will set the property of the sequence in the  modelload event (to ensure that the model is already loaded) and then  the code will execute the play of the first step with some timeout of 1 second. Loadsequnece method could also be called from any UI elements (button , change of slider ... etc.)

I think there is no problem to set different sequences at runtime with the method setWidgetProp and play them -but my experience is that it will work only in preview. On the HoloLens the animation will work only if the pvi file are xtracted from pvz and uploaded explicitly to the upload folder. Also, you have to pay attention that the sequence name is deferent (resource folder file name  and the  model property-> sequence)!

// $scope, $element, $attrs, $injector, $sce, $timeout, $http, $ionicPopup, and $ionicPopover services are available

$scope.app.loadsequence = function()
                { $scope.setWidgetProp('model-1', 'sequence', "app/resources/Uploaded/l-Creo 3D - Formgebung.pvi"); 
                  twx.app.fn.triggerWidgetService("model-1", 'play'); 
    }
///////
$rootScope.$on('modelLoaded', function()
               {$scope.app.loadsequence();
                console.warn("$scope.app.loadsequence() executed");                         
                                                               $timeout( function() {
                          $scope.app.loadsequence();
                          console.warn("app.loadsequence() executed");                           
                          $scope.$applyAsync();
                                     }, 1000);
                                          
                                          });

I created mulitple sequences in a model. Now i have binded it with application parameter . i want to know how can i provide values to that parameter at runtime in Home.js or elsewhere.

basically i want to change the sequence by calling different functions.

[dupatel]

Vivek Jain​: Yes, you can initialize and assign values to variables in Home.js and can also write JS functions which you would like to be called in case of some event or activity.

[vjain-21]

I am aware of initializing the variables in Home.js.

I want to know in particular about the sequence property of model and how to set it for multiple sequences.?

[A_Macierzynski · Accepted solution]

Hi,

You need to go to the widget property through the $scope. You can find that your model widget has something called sequence property.

Sequences created in Creo software are saved in PVI format and it is a part of the PVZ model file. You can try to open PVZ file as an archive to see that it contains your sequences in separated PVI files.

So now you can try with two things:

1. Assign the sequence name directly to the property like this: $scope.view.wdg['model-1'].sequence = "mySecondSequence";

2. Try to assign it by path like it is shown above. (it can be painful to figure out correct path).

I didn't test it yet, so you can give me a feedback if it is working as you want.

Regards,

Adam

Also, can check and try

$scope.view.wdg['model-1']['sequence'] = seqname;

[vjain-21]

nope this doesn't work.

[vjain-21]

We cannot directly provide sequence name. We have to find the fully qualified name which is a pain as said.

I had to download the project and go to \src\phone\components\Home.json to find out the qualified name for the sequence.

so  $scope.view.wdg['model-1'].sequence = "Uploaded/l-Creo 3D - wheelassembly1.pvi";  something of this sort works.

[A_Macierzynski]

Glad that I could help. And I can agree that this is painful to get proper sequence name without digging in the PVZ model.

I believe that the first part of path is always the same, so you can make you own JS function which will be just concatenating the path.

Hello

I've tried to use .pvi file in hololens according to proposed solution above and are getting following error.

Uncaught TypeError: Cannot read property 'stepVec' of undefined

    at vuforia-angular.js:1568

And in debug mode I'm getting error on bold marked line:

function loadSequence(url, speed, callback) {

        // ignore speed, native sequencer doesn't have such concept

        var pviParams = {

            modelID: MODEL_ID,

            url: url

        };

        renderer.loadPVI(pviParams, function (sequenceData) {

            // load completed callback

           STEPS = sequenceData.stepVec;

            TOTALSTEPS = STEPS.length;

            FIRST_STEP = 0;

            // if step 0 has acknowledgment, start on step 0, otherwise start on step 1

            if ((TOTALSTEPS > 0) && (STEPS[0].acknowledge === false) ) {

                FIRST_STEP = 1;

            }

            // ThingView might still be on step 0, but the next step to be played is CURRENT_STEP

            CURRENT_STEP = FIRST_STEP;

            if ( callback !== undefined ) {

                callback(undefined, undefined);

            }

        }, function () {

            // load failed callback

            console.log(MODEL_ID + " failed to load pvi " + url);

        });

    }

same issue here, any solutions?!

[ddeoliveira]

I had the same problem. I tried many solution..so far nothing work 100%.

Hi, 

I don't know if I've fully understood the problem that ddeoliveira and whity are experiencing, but this is how I've done something similar:

My model (model-1) has two complete separate sequences (that translated to separate .pvi files inside the .pvz). I've created two buttons that when I click each button, it will execute one of two functions: PlaySequence1 or PlaySequence2. 

PlaySequence1 will select the first sequence associated with the "l-Creo 3D - Figure 1.pvi" file and play all steps.
PlaySequence2 will select the second sequence associated to the "l-Creo 3D - Figure 2.pvi" file and play all steps within that sequence.

Code:

$scope.PlaySequence1 = function() {
 $scope.view.wdg['model-1']['sequence'] = 'l-Creo%203D%20-%20Figure%201.pvi';
 $scope.$applyAsync();
 
 $timeout(function() {
 $scope.$broadcast('app.view["model-1"].svc.playAll')
 }, 400)
};
$scope.PlaySequence2 = function() {
 $scope.view.wdg['model-1']['sequence'] = 'l-Creo%203D%20-%20Figure%202.pvi';
 $scope.$applyAsync();
 
 $timeout(function() {
 $scope.$broadcast('app.view["model-1"].svc.playAll')
 }, 400)
};

Notes on this example:
- I had to rename my .pvz to .zip and extract the files to find the name for the .pvi files (a better way might exist)

- I had to replace all spaces within the file name with %20 for this to work

Please let me know if this is in the direction you are looking for, or not? 

Thanks and all the best,
