pdfcraft-annot reads a page's 3D annotations and the model each shows: the /3DD stream, or the stream a /3DRef names (at most four deep, so a cycle ends), decoded within 256 MB and typed PRC or U3D by /Subtype. pdfcraft-engine exposes both on Document. The automation tool model3d_render picks a page's Nth 3D model, parses PRC with pdfcraft-prc, assembles and frames it with pdfcraft-prc-render from a chosen direction (default an isometric-style view, Z up), and returns the image as a PNG. U3D gives an error until a decoder lands. parity misc.3d-view moves to partial.
