Using the BOOST REGEX libraries, it is a serie of expressions to use regex in Houdini.

- Platform Linux and WinXP - Compiled for Houdini 8.0.474 and 8.1.633 - On linux compiler used: gcc 3.4 - Source* available in the zip.

It contains:

- regexMatch( string regex_pattern, string myString,int regex_engine ) //return the matching part

- isRegexMatch( string regex_pattern, string myString, int regex_engine ) // return 0 or 1

- regexReplace( string regex_pattern, string myString, string replace_with, int regex_engine ) // return the new string.

There are 3 options for regex_engine 0 - POSIX 1 - Extended POSIX 2 - PERL based regex default is PERL regex.

To install it, just put the corresponding DSO to your DSO directory. Look at the Help.txt, to see how to use it.

*Regarding the source, it is not clean code or perfect as it´s been done during free time and for free. Since there is nothing such as a free lunch, dont expect perfect code. Which doesnt reflect the way I work. Therefore feel free to make it perfect :)

A simple manual push-button Disk Cache COP. When "Cache Frames" is pressed, all input frames are written to disk. The output frames are always loaded from disk. If the input changes, the changes are not propagated to the output or cached to disk.

Tested on Linux only. Requires 8.1.701 or higher.

Speeder Tools Particles Noise Field Operator. This POP move particles using different types of noises like Sparse Convolution, Perlin Noise, Alligator, etc, with many control for the noise itself and for the noise effect over the particles. Is inspired by the Wisp tool by Ivan DeWolf.

This was originally an obj file obtained from a CGTalk Lighting Challenge posted by Jeremy Birn. I broke it down into groups and then built some procedural shaders in Vops. There are 4 lights in the scene. Plus one Ambient Occlusion light that is used in a separate pass (in Takes) and then multiplied in the Compositor.

My goal was to work with only procedural shaders.
