How to set initial view properties when add u3d into pdf using itext7

Question

I added a u3d image to a pdf (according to this example), I found the u3d image is added to the pdf but when I open the pdf with Acrobat I can't see it directly (blank block but the 3D menu), I have to right click the blank block and choose "Part Options -> Fit Visible" to make it appeared. If I am using example teapot.u3d it works (open then see). Is my u3d file too big (3 to 7 MB) but teapot.u3d only 141KB.

Here is the example code I am using:

    public void manipulatePdf(String dest) {
    PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));

    Document doc = new Document(pdfDoc);
    Rectangle rect = new Rectangle(100, 400, 400, 400);

    PdfStream stream3D = new PdfStream(pdfDoc, new FileInputStream(RESOURCE));
    stream3D.Put(PdfName.Type, new PdfName("3D"));
    stream3D.Put(PdfName.Subtype, new PdfName("U3D"));
    stream3D.SetCompressionLevel(CompressionConstants.DEFAULT_COMPRESSION);
    stream3D.Flush();

    PdfDictionary dict3D = new PdfDictionary();
    dict3D.Put(PdfName.Type, new PdfName("3DView"));
    dict3D.Put(new PdfName("XN"), new PdfString("Default"));
    dict3D.Put(new PdfName("IN"), new PdfString("Unnamed"));
    dict3D.Put(new PdfName("MS"), PdfName.M);
    dict3D.Put(new PdfName("C2W"),
            new PdfArray(new float[] { 1, 0, 0, 0, 0, -1, 0, 1, 0, 3, -235, 28 }));
    dict3D.Put(PdfName.CO, new PdfNumber(235));

    Pdf3DAnnotation annot = new Pdf3DAnnotation(rect, stream3D);
    annot.SetContents(new PdfString("3D Model"));
    annot.SetDefaultInitialView(dict3D);
    pdfDoc.AddNewPage().AddAnnotation(annot);
    doc.Close();
}

If I remove this line: "annot.SetDefaultInitialView(dict3D);" I can open and see the image but the background is black and image is dark. I am wondering the PdfDictionary in the example is not suitable for my u3d image. Not sure if different u3d image requires different PdfDictionary or initial view properties? We need to open and see the 3D image but don't know how to set the view properties. Can anyone help on this?
