[x3d-public] Renderer for x3d.py

[Brutzman, Donald (Don) (CIV)]

No renderer is planned for x3d.py.  The stated design notes that “Creating a native-Python implementation for X3D data structures appears to provide the greatest possible portability.”  That has been accomplished successfully.


We have over 4,000 scene graphs built and validated using x3d.py as part of the X3D Examples Archives.  Certainly they show how to create Python data structures containing scene graphs.

 

Building a renderer involves a Small Matter of Programming (SMOP)!  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.

Hope this is now clearer.  Happy new year.

 

all the best, Don

Subject: Renderer for x3d.py

 

Kivy appears to be the best (most community) cross-platform OpenGL library for Python.  Did you explore this option, Doug? 

 

Another, more GUI library is BeeWare Toga.

 

Web-oriented tools are Django and Flask, then choose a front-end.

 

If someone can lay out a pattern for building a renderer using x3d.py as scenegraph, with additional packages for rendering the scenegraph, maybe I can start looking into developing an Interchange profile renderer?
