This course is a comprehensive introduction to the use of VEX in Houdini. Some of what you’ll learn includes: implementing collision deformers, Laplacian and Taubin smoothing, Perlin Noise, and implementing our own fBM noise, different shaders in VEX, volume manipulation, pyroclastic noise, terrain erosion, and more. Jul 20, 2017 · Javier looks at the VEX Sample functions that come stock with every copy of Houdini. “These are, many times, overlooked” Toledo notes. “They are a very powerful vector randomization functions”. In most cases, people tend to use a simple Rand function in Houdini, but for most situations, that might not be enough. The Rand function only ... We cover writing our own functions in VEX and how to save this as a header file that can we can use inside Houdini by including it through pre-processor directives. Finally, we go over Git and how it works so we can use it throughout our project. At CGMA, I took the 2 Houdini courses for destruction – one with Keith Kamholz, Mastering Destruction in Houdini, and the other with Manuel Tausch, Intro to FX Using Houdini. I am really happy to have taken them in this order because I was still kind of new to Houdini when I took the first one, and Manuel’s course is really tough! I’m mostly just copying what you are doing while trying to understand the functions but I’m missing the fundamentals – and those are the key to come up with stuff myself. Can you make a recommendation on what programming language to learn that has the most benefit for houdini? Or should i learn specifically the houdini language? The idea - google search of creating points in vex snippets - lead to three resources: Creating Geometry With VEX by Entagma; Create UI controls from cgwiki on Vex "ch() tells Houdini to look for a channel, which is what Houdini calls a UI component, usually a slider. Hit the little plug icon to the right of the text editor, Houdini scans the ... 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 ...

MAKETRANSFORM – VEX Functions in Houdini This time we take a look at the maketransform function and what you can do with it. But more importantly when is the right time to use it over a simple transform sop. When you look for specific VEX functions be sure to check the VEX function documentation here. Some global attributes are always accesible inside VEX code, such as @Time, @Frames, which can replace the need of using $ F . Houdini has allowed him to combine his experience in 3D and scripting, taking both to new heights. David has a passion for sharing his knowledge and does his very best to make a difference in the community. Aug 15, 2015 · How to create a Magnetic Vector Field in Houdini - Tutorial A few days ago I was chatting with a fellow colleague (Jon Parker, great Houdini Artist) about magnetic fields. So I decided to create a little OTL to generate a vector field starting from a pole cloud distribution and share the workflow, since it's really simple to implement and the ... Houdini, Python, Script I typically bundle these snippets as presets in a wrangle node as I get to use most of these functions from day to day. This generally gives me a good head start for similar wrangle tasks and also aids my efficiency. The way Houdini has evolved, inserting snippets of VEX via the wrangle nodes is the new powerful standard. VEX is very C-like, but don’t feel compelled to learn C++ at a comprehensive level. Knowing Python will be far more useful, as it is tightly integrated into Houdini these days. VEX is loosely based on the C language, but takes ideas from C++ as well as the RenderMan shading language. VEX is used in several places in Houdini: Rendering – mantra uses VEX for all shading computation. Modeling – The VEX SOP allows you to write a custom surface node that manipulates point attributes. We cover writing our own functions in VEX and how to save this as a header file that can we can use inside Houdini by including it through pre-processor directives. Finally, we go over Git and how it works so we can use it throughout our project. A VEX program must contain one function whose return type is the name of the context. This is the main function of the program that is called by mantra. The compiler expects one context function per file.

Examples and suggestions for programming in VEX. Half-edges. VEX has functions that let you treat edges as unshared per-face "half-edges". Noise and randomness. Creating a surface or particle node using VOPs/VEX. VOP structs. Using assertions in VEX. You can use the assert() macro to print information while you are debugging VEX code.

Later, you’ll explore how to apply those functions in a vex-based project. Finally, you’ll dive into creating a procedural Sci-fi corridor generator that relies on programmed decision-making to get built with your new tool set. Lots. VOPs is a gui front end to VEX (hence the name; Vex Operators), which is a programming language similar to renderman's SL. If you've glimpsed at renderman shaders you'll recognise a lot of what VEX covers, eg noise functions, reading images, point clouds, vector manipulation.
