Media9 cross section add section caps by default in view file

3dembeddingjavascriptmedia9

I would like to know how to enable the 'add section caps' feature by default in a predefined view of a 3D object in PDF using the media9 package. Right now the part is hollow after making a crossection with a predefined view and I have not been able to find an answer in the documentation of the media9 package.

Here is the shell part together with the option to be enabled by default:

And here the code in the .vws file:

Maybe there is an option like "sectioncapsvisible=true" somehow?

Any help would be appreciated. Thanks in advance, Thomas

Version 1.23 of package media9 adds two new options, SECTIONCAPPING=true|false and SHOWTRANSPARENT=true|false, for use in the subsection CROSSSECT of a 3D views file. Because these settings do not have a JavaScript representation, they cannot be detected by "Get Current View" of the 3D annotation's context menu and have to be added manually.

For objects which should test if visible or not it is not possible with linestyle=dashed because all line segments are in general shorter than the ones from the dash and they will be sorted before drawn. However, you can delete some segments from such a line:

\documentclass{article}
\usepackage{pst-solides3d}
\pagestyle{empty}
\begin{document}
\begin{pspicture}(-4,-4)(10,10)
\psset{viewpoint=50 45 20 rtp2xyz,Decran=25,lightsrc=viewpoint,lightintensity=1.25}
\psSolid[object=sphere,r=3.5,ngrid=30 30,hue =0 0.5,grid=false]
\defFunction[algebraic]{sectioncut}(t)
    {3.5*cos(0.5236)*cos(t)}
    {3.5*cos(0.5236)*sin(t)}
    {3.5*sin(0.5236)}
\psSolid[object=courbe,r=0,range=-0.75 2.5,resolution=90,
    rm=1 2 88{} for, % delete every second segment
    function=sectioncut]
\end{pspicture}
\end{document}

strokeopacity in general should work and the shadowcolor cannot be modified by now.

[Tex/LaTex] LaTeX 3D PDF with U3D file and media9: add a view at runtime

Update:

Current versions of Acrobat Reader DC allow users to add new 3D views at runtime and to save them with the PDF file. Adding new 3D views does not require recompilation of the PDF from the TeX source anymore.

~~No, this is not possible in AdobeReader.~~

At runtime, a user may manipulate the 3D object in AdobeReader and produce new VIEW sections via the context menu (mouse right click), provided the 3Dmenu option was set during compilation of the PDF. He can add VIEW sections to an existing or to a blank new views-file (via copy/paste from the JavaScript console) and associate the modified views-file with the u3d/prc file via option 3Dviews during the next LaTeX run.

Thus, the user needs the complete LaTeX document source plus the u3d/prc files to be embedded and recompile the whole thing with the new view added.

Note that JavaScript cannot write to files directly, for security reasons.

The views-file is not embedded verbatim into the document, but parsed by LaTeX and translated into PDF objects when compiling the LaTeX document source.
