Perfect, thank you! This very nicely shows the meaning of
metallic/roughness terms in PBR.

I added the image and links to
https://github.com/michaliskambi/x3d-tests/wiki/What-is-PBR-and-why-do-we-want-it-in-X3D%3F

I also added the arrows and text (metallic/roughness=0.0/1.0) on your
image. The image (in XCF version, where one can easily edit the text)
is on https://github.com/michaliskambi/x3d-tests/tree/master/pbr/images
.
