Indeed writing an all-purpose renderer is much harder, and a historically a moving horizon for computer graphics every year. This is why X3DJSAIL and X3DPSAIL can be used by others. Rendering is avoided intentionally in the design of these libraries and without any impediment to progress, since each library has various export methods for producing X3D and Classic VRML, also for publishing to a web page using X_ITE or X3DOM. Boom presto, wide portability for a large number of X3D-capable tools and viewable rendering anywhere.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><ul style='margin-top:0in' type=disc><li class=MsoListParagraph style='margin-left:0in;mso-list:l0 level1 lfo1'>https://en.wikipedia.org/wiki/Small_matter_of_programming<o:p></o:p></li></ul><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Hope this is now clearer.
