If you're having trouble understanding Vue's filters, then you could look at my filter tutorial which discusses filters but not procedurals.

I think creating a wood texture that looks good close-up is very difficult using Vue's procedural functions.

For large scale wood production that has no tiling, I've been experimenting with mixing two materials with mapped pictures. The idea is to use the mixing function to break up the tiling.
