Hi,
to make the first steps easier for new comers like me, I think it would be good to have 3 good examples of how to visualize with:

• QT integrated viewer
• output to images or 3d-formats (png and obj for example) to disk
• output to numpy arrays to import the data in your prefered 3D package (Houdini, Blender, etc...)

Also having the images on your website/github to point to the according .py in the example folder would help quickly finding the right example for what people want to learn.

All good suggestions! I agree that dealing with outputs and finding the right examples are the biggest current issues :-)
