A fast, browser-based reference for SideFX Houdini artists: 70+ copy-paste VEX snippets, an expression & HScript cheatsheet, a global-variables table and a $JOB project generator. Free, client-side, no login - here's how it all works.
Everything in one browser tab - nothing to install
No setup and no account. Open the page, grab what you need and drop it straight into a wrangle, a parameter or your shell.
Filter an idiomatic library across ten categories - point clouds, attributes, vectors & matrices, noise, geometry, groups, ramps, strings and more. Each card explains what the snippet does and assumes an Attribute Wrangle in point context unless noted.
// Average colour of nearby points
int h = pcopen(0,"P",@P,2.0,12);
vector c = pcfilter(h,"Cd");
@Cd = c;
Every snippet, expression and global variable has a copy button. Hit it and the code is on your clipboard - paste it straight into the wrangle's snippet field or any parameter. A toast confirms the copy; nothing ever leaves your machine.
// Frame-based value in a parameter
$F // current frame
$FF/$FPS // seconds
fit($F,1,240,0,1) // normalise
Type a project name and the generator outputs the standard SideFX folder tree - geo, hip, render, tex, scripts, abc and the rest - plus the ready-to-run shell commands to create it. Copy the tree or the commands and your $JOB is set up in seconds.
mkdir -p myShow/{geo,hip,render,
tex,scripts,abc,comp,flip,
audio,desk,render/ifd}
# set $JOB to myShow and go
Idiomatic, ready-to-paste code across ten categories - the patterns you reach for every day.
A cheatsheet of the channel, math and string expressions you use in parameters - with notes.
A searchable table of Houdini globals - @P, @N, @ptnum, @Time and more, with meanings.
The standard SideFX folder tree plus shell commands to scaffold a clean project instantly.
Everything runs in your browser. No login, no account, nothing you do ever leaves your machine.
Forever free. Installs as a PWA, so the snippets and cheatsheets work even with no connection.
Switch between them with the tabs at the top of the Lab - all free, all instant.
A searchable, category-filtered library of 70+ snippets. Each card has a title, a one-line explanation and a copy button - drop them into an Attribute Wrangle and tweak.
A grouped cheatsheet of the expressions you live in inside parameters - channel references, frame & time, math, and string ops - each with a short note on what it does.
A reference table of Houdini's built-in globals you read and write in VEX - position, normals, IDs, counts and time - with the meaning of each at a glance.
Name a project and get the standard SideFX $JOB folder tree plus the shell commands to create it - copy either and you have a clean, consistent project layout in seconds.
It's completely free - no account, no install, nothing leaves your machine. Just open it and grab what you need.
