I think I want something based on X3DObject in X3DJSAIL, probably as an extension of X3DJSAIL, so your help would be appreciated. I am thinking something like</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>X3DObject obj = X3DObject.generateSemiRandomScenegraph(seed);</p><p class=MsoNormal>X3DObject obj2 = X3DObject.generateCompleteScenegraph(seed);</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Then similar to how toStringX3D() goes down through hierarchy, I would have a generate…Scenegraph(); at each node. I would need some probabilistic or occurrence-based configuration to generate the number of children and which attributes get set and which nodes get generated. My question becomes, how to I generate things which are dependent on each other? Like DEF/USE, Routes, and IndexedFaceSet attributes, for example. I think I can do this through something similar to validation, but I haven’t spent much time thinking about it--generateValid()??? Have you spent anytime thinking about it?</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>What do you think about extending X3DJSAIL, and how do I go about getting my changes integrated? Should I start a similar independent stylesheet which just does generation? Should I output a different language than Java?</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Your thoughts are welcome!</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The only reason I am doing this Is to test the schema. If you have a better approach, let me know!</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Also, if anyone has done any occurrence-based analysis of X3D documents, I would be eager to hear about it.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>John</p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
