I'm a professor of mathematics at the University of North Carolina Asheville. I've also done a fair amount of consulting work over the years focusing on scientific and data visualization.
I'm happy to be part of the first Observable Ambassador's cohort.
Rotating the scenes is fairly awkward. You might want to consider adding X3DOM's turntable navigation:
scene.append("navigationinfo").attr("type", "turntable");
Unfortunately this doesn't play well with your axis setup and initial viewpoint.
Hi, thanks for sharing this really neat library. Does giving color here to create_indexedLineSet actually do anything? I want to change the line color but it seems not.
That's correct, color is not currently implemented for indexedLineSet. I believe that X3Dom (on which PlotX3D is built) does provide a way to color an indexedLineSet but that I didn't implement it.
