Houdini VEX Volume 2

Upon general request, CmiVFX is proud announce its two first volumes of new series of Houdini videos about VEX and VOPs. VEX is one of these things that makes Houdini really unique. Initially designed to be a powerful shading language, its paradigm has been extended to enable users to create new custom operators (like new SOPs, POPs, CHOPs). With the Houdini visual programming philosophy, VEX comes as a new dedicated context: VOPS where the data flow of your program is represented by custom nodes that wrap mathematical functions. VEX programming is so immense of a field that you could recreate almost half of the nodSOP context, maybe the easiest one to master: this means you'll learn how to create new surface operators, new modeling tools, new deformers with VEX/VOPs. It is at the same time an introduction to VEX concepts that are shared among all the various contexts, that we will reuse in our videos about rendering and shader development, or in videos about particle animation .Seashells, global deformers, water ripples... while being a language reference, these videos are intended to be a great cookbook for useful mathematical formulas.

Seashells
Discover what is behind the algorithmic beauty of seashells, how nature is doing math, producing out of the same mathematical model an immense diversity of beautiful seashell silhouettes. Water Ripples: Learn how to simulate water ripples due to raindrops collision on the surface of a lake. Connect your VEX operator to a particle system and let it rain!

Multiple Inputs: In the same spirit as Renderman's DSO ( dynamic shared object), learn how to use several inputs in a VEX SOP, so that you can have helper geometries. The possibilities are endless, and you can now see Houdini's SOPs and CHOPs as an abstract extension of VEX data types and VEX functions.

VEX and VOP Workflow: Learn how you can create new VEX functions as well as new custom VOPs. This means that you're building operators whose purpose is to build operators... Add this to Digital Assets and Python meta-commands, and you get an unprecedented level of hierarchical customization. Learn how to integrate VEX and VOP in the same network.

Math
Matrices, polar coordinates, trigonometry, waves and later, noise octave summation, fourier transform, barycentric coordinates. Sound scary? Well it's not. Your new mathematician / personal trainer takes you by the hand in this world to spark your nostalgia about all that. You will be surprised to find all this math enjoyable again.

Rich as Book,Easy as a Video

This set of videos is the most comprehensive documentation you will find about VEX and VOPs. You will effortlessly progress through concrete examples, All the examples have been carefully chosen to leave no gaps in your education. The result is something which is as dense as a book, that you regularly come back to watch when your stuck on a project.

David Gary
French, and has a Bachelor Degree in Pure Mathematics, a Master Degree in Philosophy and is preparing his PhD in the interdisciplinary field of philosophy of mathematics, phenomenology and cognitive sciences. Aside of his studies, he's directed a dozen of short movies and video clips, being a director/video instructor. He began to be a strong CG specialist since a long time using various tools as 3dsmax, Maya, Houdini.
