Create 3D comments in PDF 3D

[[email protected]]

First of all, congratulations to the developers for this great component.

I'm using it to generate PDF documents containing a 3D model. I have seen that from Acrobat Reader it is possible to generate comments on a specific coordinate of the 3D model, and I would like to know if this is possible to do it directly from code using Spire.PDF.

Thank you very much for your help!

Hi,

Thanks for your inquiry and sorry for the lately reply as weekend.
Sorry that our Spire.PDF doesn't support adding 3D comments at present. We will add the new feature to our future upgrade list. Once it is achieved in the future, we will let you know. Besides, could you please provide a desired file so that our DEV team can better investigate it? Thanks in advance.

Sincerely,
Anna

            //Add a new page to it.
            PdfPageBase page = doc.Pages.Add();

            //Draw a rectangle on the page to define the canvas area for the 3D file.
            Rectangle rt = new Rectangle(0, 80, 200, 200);

            //Initialize a new object of Pdf3DAnnotation, load the .u3d file as 3D annotation.
            Pdf3DAnnotation annotation = new Pdf3DAnnotation(rt, @"..\..\..\..\..\..\Data\CreatePdf3DAnnotation.u3d");
            annotation.Activation = new Pdf3DActivation();
            annotation.Activation.ActivationMode = Pdf3DActivationMode.PageOpen;

            //Define a 3D view mode.
            Pdf3DView View = new Pdf3DView();
            View.Background = new Pdf3DBackground(new PdfRGBColor(Color.Purple));
            View.ViewNodeName = "3DAnnotation";
            View.RenderMode = new Pdf3DRendermode(Pdf3DRenderStyle.Solid);
            View.InternalName = "3DAnnotation";
            View.LightingScheme = new Pdf3DLighting();
            View.LightingScheme.Style = Pdf3DLightingStyle.Day;

            //Set the 3D view mode for the annotation.
            annotation.Views.Add(View);

            //Add the annotation to Pdf.
            page.AnnotationsWidget.Add(annotation);

            String result = "CreatePdf3DAnnotation_out.pdf";

            //Save the document
            doc.SaveToFile(result);
