Not at all Mike. Thanks for letting me know. Glad you found it useful.

Cheers,

Thanks for this, Andy! You have explained something that has eluded me for a while into an exceptionally simple concept. Thanks for this!

Thanks Avik.

My advice would be to not focus on the specifics of any particular package yet. The problem is that each 3D app usually has it’s own way of handling the maths. By looking at the app first, you’re putting the cart before the horse.

Try learning the theory first. It might seem like more work, but it provides a good consistent foundation to start from.

To that end, I can totally recommend having a look at the videos here:

If you need Houdini specifics, then http://forums.odforce.net/ is the place to go.

Often, it can be easier in Houdini to do the maths by writing code with the Inline VOP. You can find more information on that here: http://www.andynicholas.com/?p=19

Cheers,

great post. made it sound like a piece of cake!
I’d like to know more about operational mathematics involved with SideFx Houdini. Can you 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!

You must have been my teacher at University. I would have 20 (A) in Math… Damn!!!! It’s so simple and I never understood what was about. Next year I’ll finish it fou sure. “Golden material” as Mario said. And it makes me feel that no one ever explained it to me in a simple way. Thank you for sharing.
