I’d like to know more about operational mathematics involved with Houdini. Can anyone guide me to some resources on the internet or books. I’m finding it difficult to compute equations for normals and other attributes which require a procedural approach. Thanks in advance!

Could you tell us a little bit more about what you want to do ? Normal is… shading normal or geometry normal ?

normal as in case of both shading and alignment of secondary objects.
