Wrangle Nodes

See Wrangle Node Examples


Wrangle nodes are an extremely powerful and easy way to add code/customized nodes to your houdini network. See also VEX/VOPS and a little Python

Wrangle nodes use a subset of the VEX language, sometimes referred to as VEX snippets
(like vex with fewer high level constructs). If you have a background in C++ the syntax will come easily with a few added features. Under Wrangle node examples you will see an increasing set of tutorials and example files. The best way to learn VEX is to use it to solve a problem.

Why use them? VEX or point wrangle nodes are 10x faster than the point SOP!

When getting started, some things to node are:
 In VEX (work in wrangle too)
 In Wrangle
 int
 i
 float
 f
 vector
 v  or v4
 string
 s
Arrays:
int myarray[];
Also arrays! Either attribute or local
i[]@myarray;




TIP: C++ is very useful for understanding VEX.

TIP: For a list of functions available in vex refer to the documentation or, on linux, type vcc -X sop in a terminal shell
(note for those on Windows go to SideEffectsSoftware/CommandLineToolsVersionNumber to open a window similar to unix (but is ms-dos with Houdini env initialized)
