ofxPTAM

You will find that you have to make and copy all the PTAM requierd libraries and soureces. You can fing a detailed tutorail of how to do it on MacOSX 10.6 and 10.7 at: http://www.patriciogonzalezvivo.com/blog/?p=547

Prepare everything for seting your addon

  • Print the calibration pattern, run the CameraCalibrator on PTAM directory. Take some sanpshoots, optimize and save. That will make a camera.cfg

  • Move PTAM directory inside ofxPTAM addon and rename it include. So at the end every PTAM source could be found at ofxPTAM/include/

  • Copy need headers into include directory and replace your compiled libraries.

cd ofxPTAM
cp -r /usr/local/include/cvd include/
cp -r /usr/local/include/gvars3 include/
cp -r /usr/local/lib/libcvd* lib/osx/
cp -r /usr/local/lib/libGVars3* lib/osx/
  • On OSX replace GL/*.h for OpenGL/*.h on ofxPTAM/include/cvd/gl_helpers.h
//#include <GL/gl.h>
//#include <GL/glu.h>

#include <OpenGL/gl.h>
#include <OpenGL/glu.h>

  • Add #undef check on the begining of ofxPTAM/include/TooN/TooN.h
#ifdef check
#undef check
#endif

// ...

  • Put ofxPTAM/include/cvd/Linux/capture_logic.cxx code between:
#ifdef LINUX

    while(vd.pending())

    // ... all the code

    }

#endif
  • Replace all Point type calls for BPoint on ofxPTAM/include/Bundle.h and ofxPTAM/include/Bundle.cc

  • Delete reference for main()

cd ofxPTAM/include
rm main.cc
rm CammeraCalibration.h
rm CammeraCalibration.h

Adding ofxPTAM addon to a oF project

  • Add the include and lib directory at the Project.xcconfig
//THE PATH TO THE ROOT OF OUR OF PATH RELATIVE TO THIS PROJECT.
//THIS NEEDS TO BE DEFINED BEFORE CoreOF.xcconfig IS INCLUDED
OF_PATH = ../../..

//THIS HAS ALL THE HEADER AND LIBS FOR OF CORE
#include "../../../libs/openFrameworksCompiled/project/osx/CoreOF.xcconfig"

OTHER_LDFLAGS = $(OF_CORE_LIBS) $(OF_PATH)/addons/ofxPTAM/lib/osx/libcvd-0.8.dylib
HEADER_SEARCH_PATHS = $(OF_CORE_HEADERS) $(OF_PATH)/addons/ofxPTAM/include
  • Add vecLib.framework

  • Copy ofxPTAM/include/camera.cfg to bin/data directory
