Point clouds to mesh conversion

1. PointSet >  Subsampling - Montecarlo or Poisson
Samples: enter the number of points that you want to have in the end - usually the initial size is millions - you can see it at the bottom of the window in Vertices:

2. PointSet > Compute normals for point sets
Neighbour num: 20
Smooth iteration: 5

3. Surface Reconstruction > Poisson
Surface Reconstruction > Ball Pivoting worked for me

Pointcloud Streaming on Ubuntu

1. compile and run the server

./bin/pcl_openni_mobile_server -p 11111

as described here:
http://www.pointclouds.org/documentation/tutorials/mobile_streaming.php 


2. Download Android app
git clone https://github.com/PointCloudLibrary/mobile.git

3. Download Android SDK

android-ndk-r5b can be found here:

http://developer.android.com/sdk/ndk/index.html

Read its documentation, specifically the Standalone Toolchain.

Assumming you read the documentation, follow steps for creating a standalone
toolchain.
  export NDK=~/android-ndk-r5b
  $NDK/build/tools/make-standalone-toolchain.sh --platform=android-5 \
    --install-dir=$HOME/android-toolchain

android-sdk can be found here:
http://developer.android.com/sdk/index.html
Please install that, and add it to your path.
  ANDROID_SDK=~/android-sdk-linux_86
  export PATH=$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$PATH

4. Download android-cmake
sudo apt-get install mercurial
hg clone https://code.google.com/p/android-cmake/

5. Install boost using android-cmake scripts

Introduction
-------------

Let's build boost for android.  Assuming you are using the alias trick for android-cmake:
  export ANDTOOLCHAIN=$ANDROID_CMAKE/toolchain/android.toolchain.cmake
  alias android-cmake='cmake -DCMAKE_TOOLCHAIN_FILE=$ANDTOOLCHAIN '

I. Build the native code
------------------------

cd android-cmake/common-libs/boost
  
Pull down and patch the boost libraries for android.
 sh ./get_boost.sh
 mkdir build
 cd build
 android-cmake ..
 make

To build with for targets other than armeabi-v7a, edit the cache. (cmake-gui,ccmake)

  
II. Use boost in your projects
----------------

See the hello-boost project under samples.

find_package(Boost REQUIRED filesystem system)

include_directories(${Boost_INCLUDE_DIRS})

add_library(my_target SHARED ${my_target_srcs})
target_link_libraries(my_target ${Boost_LIBRARIES})
