Version 1.0 of ofxOpenNI has been deprecated (originally the master and develop branches)

You can get a copy by downloading a zip from here: https://github.com/gameoverhack/ofxOpenNI/tree/v1.0 Or by browsing the tag v1.0 here: https://github.com/gameoverhack/ofxOpenNI/tags

Version 2.0beta is now being actively developed using experimental, develop and master branches.

The general idea is that Master should be stable, Develop should be where changes are happening but mostly should be working and Experimental is pretty much, well back to be experimental!!

OFXOPENNI FOR MAC & WIN

The ofxOpenNI module is a wrapper for the openNI + NITE + SensorKinect libraries/middleware for openFrameworks.

Tested and working on Mac OSX (10.6.8), Linux (Ubuntu 10.10 64 & 32), Windows 7 (VS2010 and Codeblocks)

Latest changes (11/11/12) Deprecated version 1.0 Updating read me Corrected scoped lock issues for threading Fixed copy constructer for Users (was breaking mask textures)

Latest changes (09/01/2012): Updated to latest drivers (OpenNI 1.5.2.7 unstable, NITE 1.5.2.7 , SensorKinect (Avin) 5.1.0.25) for Mac portable dylibs. Tested with Win32 latest unstable and linux 64 latest unstable drivers and is working (NOTE: Win 7 64 bit users I may need to add a 64 bit version of the lib)...will test soon Added a weird hack to make sure the ofRootPath is set before calling an init on the Context - for some reason on of007 I need to do this?!? Deprecated support for of062 - all example projects are for of007: Xcode, Codeblocks (Win and Linux64), VS2010 Fixed a bug in the example where my demo of MaskPixels was making everything go black...for some reason glEnableBlend(GL_DST_COLOR, GL_ZERO) is not behaving like I expect Restructured the examples folder, including going back to having the config folder already in the bin/data/openni path

Previous changes: Updated to latest drivers (OpenNI 1.1.0.41 unstable, NITE 1.3.1.5 , SensorKinect (Avin) 5.0.1.32) Compiled these as portable dylibs for Mac OSX (see NOTE ABOUT PORTABILITY below) Added Codeblocks support for Windows Added Linux support (Codeblocks) Bugfixed HandTracker and GestureGenerator (was ignoring initial gestures due to timestamp issue) Added setMaxNumberOfUsers to UserGenerator (although memory allocation is still done with a define for MAX_NUMBER_USERS cpu intense iterations for point clouds and masks can now be limited by setting a 'soft' max using this function. TODO: make the arrays/mem dynamically allocate) Other minor bug fixes, etc Updated this readme...

INSTALLATION

Go to your addons directory, and follow these commands if you're using git

<pre> git clone https://github.com/gameoverhack/ofxOpenNI.git cd ofxOpenNI git checkout master </pre>

or if you wanna see what I'm working on:

<pre> git checkout experimental </pre>

Please make your pull requests on the Develop or Experimental branches!!!

NOTE ABOUT PORTABILITY

On Mac OSX I've compiled the OpenNI, NITE and SensorKinect drivers and then modified the dylibs so they can sit in the bin/data/openni/libs folder. These are truly portable. On Windows I realised my solution was never really portable, and after banging my head against the problem I've decided that either a) it's not possible and/or b) I can't do it. Either way you're gonna have to install the drivers as per the instructions below. Copying the contents of ofxOpenNI/win/copy_to_data_openni_path (ie., the folder called libs and the file OpenNI.lib that is in it) really just saves you the trouble of pointing VS or CB at this file in your OpenNI install path. I've left it like this for now as people do seem to find linking confusing at first, but if you wanna do away with it completely then simply (;-) let your compiler know where OpenNI.lib is on your hard drive. A final note: this means that all the config settings inside data/openni/config are not doing anything on Windows; go find them in your openNI install path instead! On Linux it's a similar story except more so: either a) I can't do it or b) I can't do it. You don't need to copy anything to the data/openni path and the config files in data/openni/data are similarly cosmetic - go find them scattered in /usr/bin/, /usr/lib/, /usr/include/ni etc

DRIVERS & GETTING THE EXAMPLES TO WORK

Mac OS X:

You don't need to do any install of drivers if you don't want, just:

• Do the git magic above or somehow else get a copy of ofxOpenNI into your addons directory
• Copy 'example' folder to yourofdir/apps/yourworkingdir
• Copy the folder called 'lib' from 'ofxOpenNI/mac/copy_to_data_openni_path' to your 'bin/data/openni' directory of your example.
• Rename or copy one of the src-SomeExample-Level (eg., src-UserAndCloud-Medium) to just 'src'
• You might need to clean before building each time you change the src folder

Windows & Linux:

• Install openNI (http://www.openni.org/Downloads/OpenNIModules.aspx OR http://github.com/openni)
• Install NITE (http://www.openni.org/Downloads/OpenNIModules.aspx)
• Install SensorKinect drivers (make sure you use https://github.com/avin2/SensorKinect modified drivers, not the standard Prime Sense drivers if you're using a Kinect...might be able to use their openNI install too, but I haven't checked)
• Rename or copy one of the src-SomeExample-Level (eg., src-UserAndCloud-Medium) to just 'src'
• You might need to clean before building each time you change the src folder

then on Windows:

• Copy 'example' folder to yourofdir/apps/yourworkingdir
• Copy the 'ofxOpenNI/win/copy_to_data_openni_path' to your bin/data/openni directory of your example or link as per above PORTABILITY notes.
• Rename or copy one of the src-SomeExample-Level (eg., src-UserAndCloud-Medium) to just 'src'
• You might need to clean before building each time you change the src folder

or on Linux:

• Just copy 'example' folder to yourofdir/apps/yourworkingdir
• Rename or copy one of the src-SomeExample-Level (eg., src-UserAndCloud-Medium) to just 'src'
• You might need to clean before building each time you change the src folder

DRIVERS & SETTING UP YOUR OWN PROJECTS

PLEASE NOTE I AM WORKING ON CHANGING HOW ALL THIS WORKS SO THAT YOU CAN JUST USE THE PROJECT GENERATOR - HOWEVER THAT WILL BREAK PORTABILITY - BUT I THINK IT'S WORTH IT!!

The easiest thing to do is to make a copy of the included examples and then gut the testApp.h and testApp.cpp for making a new project, but below are some pointers on making your own projects. Forgive me (and remind me) if I forget some steps.

Mac OS X:

You don't need to do any install of drivers if you don't want, just:

• Do the git magic above or somehow else get a copy of ofxOpenNI into your addons directory
• Make a new project (in 072 by copying emptyExample folder from the examples/emptyExamples directory into your working path -> something like ofFolder/apps/dev/)
• Copy the 'bin' folder from 'examples/opeNI-SimpleExamples/' and replace the 'bin' folder in your emptyExample (this is largely so you get the right folder structure and config files)
• Copy the folder called 'lib' from 'ofxOpenNI/mac/copy_to_data_openni_path' to your 'bin/data/openni' directory of your emptyExample
• In Xcode make a new Group called 'ofxOpenNI' under 'Addons' (right or control click the 'Addons' Group, select Add->New Group)
• Drag the 'src' and 'include' folders from inside the ofxOpenNI folder (in your addons directory) into the Group 'ofxOpenNI' you just made.
• Drag the folder 'lib' from bin/data/openni (the one you just copied) into the Group 'ofxOpenNI'
• Add #include "ofxOpenNI.h" at the top of your testApp.h (or in whatever class you're using ofxOpenNI)
