Several shaders (like parallaxAt) refer to the normal, tangent and binormal as vertex input parameters. The normals can be either calculated automaticaly or defined in the vertex tag:
Code:
<v x="-6.878592" y="-1.970000" z="2.705635" u="0.138820" v="-0.683297" nx="-0.000000" ny="0.000000" nz="-1.000000"/>
this is clear, but how about the tangents and binormals?

You might want to join the IRC channel at #crystalspace @ freenode.net and ask thebolt or res.
I doubt many other people but them would know about that, and I don't think they ever come in this forum...
