u3d file in PDF document?

[fff]

Hi all,

Any small wpf example on how to insert an u3d into a pdf ?

Documentation has nothing, and forum has just a broken link to a winform sample

Seems SF lib has a lot of parameters for that, but these are hard to guess

--> wpf ? any sample ?

Thanks,

Fabrice

Hi Fabrice, 

We have created simple sample to “Insert an U3D into PDF document” in WPF platform. 

Please find the sample from the below link. 

http://www.syncfusion.com/downloads/support/forum/131363/ze/WpfApplication1-713385290.zip  

Please run the sample and let us know if you need further assistance on this.

Hi Sowmiya,

Thanks for the sample - this is the minimal that is at the "Annotation" section.

This sample is using the default Acrobat Reader view:

• object is centered correctly (this is the VERY good point)
• object has no lightning
• background is so dark that almost nothing is visible

The last two are not OK of course. So two options I spend the 2 days to investigate without success so far:

option #1: try to use the default view, but changing is background+lightning+rendering

No success so far. For example, your sample http://help.syncfusion.com/cr/cref_files/windowsforms/pdf/Syncfusion.Pdf.Base~Syncfusion.Pdf.Interactive.Pdf3DBackground.html

does not work, creating an "Either ViewNodeName or CameraToWorldMatrix properties must be specified." error, same error as in many samples in your pdf3d documentation ... likely some breaking changes have been introduced since. (you should escalate on that likely)

Option #2: create additionnal view

This work great to set background+lightning+rendering, ... BUT

Can't work out how to set the cameraToModel matrix, so that the object is centered whatever/wherever the loaded model is. So final user may see an empty view :(

Maybe there is another way with some ViewNodeName to point the camera to the object automatically, but can't work it out either !?

--> Can you help on either method #1 or method #2 ?

Thanks,

Fabrice

Hi Fabrice,  

We have created sample to “Insert an U3D into PDF Document with Pdf3DView” by set the value to the CameraToWorldMatrix. Either ViewNodeName or CameraToWorldMartix must be specified for the creation of Pdf3DView with changing Background, Lighting and Rendering. 

Please find the Sample from the below link :

Please run the sample in your side and let us know if you need further assistance on this.

Hi Sowmiya,

Yes this is like my option #2 that I have now done many timles in the last days.

Please read my previous message: this with fixed cameraToWorld matrix is NOT solving the problem (again read previous to see why)

If you like option #2 as you just did: do you have a way to focus on object, either with node (you mention it but you do not say a solution) or to set automatically the correct matrix to any object that can possibly be located in any direction in the 3D space?

Or do you have an option #1 with corrected bug ? (and benefit from Adobe automatic camera orientation + focus)

Thanks in advance,

Fabrice

Hi Fabrice,  

We have created sample to “Insert an U3D into PDF Document with Pdf3DView” by focus on object with the ViewNodeName. In the creation of additional view with ViewNodeName, Internal name of the Pdf3DView must be specified.  

Please find the Sample from the below link : 

http://www.syncfusion.com/downloads/support/forum/131363/ze/WpfApplication1789943121.zip  

Option 1:  

As we said earlier we must specify the ViewNodeName and internal name to avoid the exception, please refer the updated sample 

Option 2: 

We cannot set the C2W matrix automatically.We have to provide the matrix value manually in the below format. 

[left_x left_y left_z up_x up_y up_z view_x view_y view_z trans_x trans_y trans_z] 

Please run the sample and check whether your requirement achieved at your end. Let us know if you need further assistance on this.

Thanks a lot Sowmiya !

(For others: the project file has some error when reconstructing in VS2015, but the .cs content is perfectly usable)

"Funny" how a simple view.ViewNodeName = "whatever_here_at_least_1_char";

 that brings nothing to the 3D & camera definition ... makes it works (was not in your online examples at time of writing ; should be added to make your examples work)

Thanks again & hope it will help others also.
