Hi Paul,
depending on what you are trying to achieve, you've got to update the
planes every frame in the way you mentioned.
If your matrix is somehow connected to the View or Modeling matrices,
you need to update them.
You can use a updateCallback or look into the samples for TexGenNode IIRC.

you absolutely need to enable GL_LINE_SMOOTH and GL_BLEND and to setup
