There is a simple extension in view3dscene to specify bump mapping 
(http://castle-engine.sourceforge.net/x3d_extensions.php#section_ext_bump_mapping 
).

There is also a more involved, but also more flexible 
CommonSurfaceShader for InstantReality 
(http://doc.instantreality.org/tutorial/commonsurfaceshader/ ). Although 
I don't know whether it's available in Interchange mode.

I would love to see X3D spec extended to incorporate one of these bump 
mapping methods :)
