[x3d-public] Mayavi

Fri Aug 30 13:31:30 PDT 2019

Hi Don, 

Indeed, I have been keeping an eye out for all your ongoing activities on the Python front. Lurking from the shadows, it’s great to see this coming along. I can see that it will really be a key asset for facilitating the generation of models. 

When it comes to mayavi, I suspect that we would get the best use out of it if we could tie the x3d package directly to the “savefig” function of that module. Ideally, the user could then call the high-level functions of mayavi to plot complex 3D functions, shapes, etc … to create x3d content, without the need to worry about the intermediate layers of defining the detailed x3d nodes. 

In other words, we might be talking about a bypass of the VTK exporter inside mayavi - or a revamp of the VTK exporter to use the x3d package. But this of course should be looked at only once the x3d module reaches a reasonable level of maturity/stability.

Either way, I’ll be between jobs in the coming months, but would be happy (and should have some time) to start contributing towards assembling tests and examples for the x3d module based on real astro data. 

Cheers, 
Frédéric

Am thinking that we might be ready in about a month or so to compare whether the new approach can catch up to what you showed in 2015.  Perhaps we might even collaboratively create a jupyter notebook for that reconstruction!

As far as I understand them, the X3D export functionalities of Mayavi are actually those from the VTK X3D exporter, which it wraps around. These have (had ?) a series of annoying limitations which made the process of creating X3D models that way a bit too “manual” for my taste … However, the easy of use of this tool, which is very reminiscent of matplotlib, was more than enough to outweigh its disadvantages (in my opinion).
