It would be nice to have an PRC (U3D) output from Maxima (VTK)
- for including 3D graphics into PDF documents.
So far there is a possibility to obtain VRML files from Maxima
VTK interface and convert them with use of Meshlab into U3D (but without
coloring and axes). See example at
https://www.math.muni.cz/~plch/maxima.pdf.
Or VTK -> IDTF export? With free IDTFConverter we can simply create
U3D files (as in Sage).
With best regards
