Dear All, since ConTeXt lacks support for embedding 3D models (U3D or PRC) into PDF (btw, is pdf annotations support in context/luatex combination fit for end-user or is "in transition"?) I have tried to embed some 3D PDFs from http://asymptote.sourceforge.net/gallery/3D%20graphs/ and http://www.iaas.msu.ru/tmp/u3d/pdf/ using \externalfigure[3dpf.pdf] \startpagefigure[3dpdf.pdf]\stoppagefigure \copypages[3dpdf.pdf][n=1] but only the preview (flat) images show up, not the 3D model, that must appear after clicking on it in Adobe Reader. File size shows that the 3D annotation data was not taken from the 3D PDF file into ConTeXt output. Any advice on possible workarounds? Any hope for ConTeXt fixes? Or making a link to an external PDF file is the only option for now? Sincerely, Michail PS. I have seen the code from Renaud AUBIN in the "U3D (embedded 3D objects)" thread, http://www.ntg.nl/pipermail/ntg-context/2006/020220.html but it is too ugly and old a hack to start any work from.
