[x3d-public] x3d-public Digest, Vol 132, Issue 35

[Andreas Plesch]

For comparison, here is a how the Khronos Flight Helmet model looks
with just a headlight in x3dom.

Explore other models with different IBL and tonemapping here:

The next step for x3dom may be to try PhysicalMaterial outside of
gltf, since sofar the node was almost exclusively used constructed
during gltf import.

Cheers,

Andreas

> - With (Phong) Material in X3D v3 (only diffuse):
