• Get Mac Os Big Sur

This tutorial explains how to build the Point Cloud Libraryfrom MacPorts and source on Mac OS X platforms, and tries to guide youthrough the download and building of all the required dependencies.

Before getting started download and install the following prerequisites forMac OS X:

• XCode (https://developer.apple.com/xcode/)

  Apple’s powerful integrated development environment

• MacPorts (http://www.macports.org)

  An open-source community initiative to design an easy-to-usesystem for compiling, installing, and upgrading either command-line, X11 orAqua based open-source software on the Mac OS X operating system.

In order to compile every component of the PCL library we need to download andcompile a series of 3rd party library dependencies. We’ll cover the building,compiling and installing of everything in the following sections:

Required

The following libraries are Required to build PCL.

• CMake version >= 3.5.0 (http://www.cmake.org)

  Cross-platform, open-source build system.

  Note

  Though not a dependency per se, the PCL community relies heavily on CMakefor the libraries build process.

• Boost version >= 1.46.1 (http://www.boost.org/)

  Provides free peer-reviewed portable C++ source libraries. Used for sharedpointers, and threading.

• Eigen version >= 3.0.0 (http://eigen.tuxfamily.org/)

  Unified matrix library. Used as the matrix backend for SSE optimized math.

• FLANN version >= 1.6.8(http://www.cs.ubc.ca/research/flann/)Library for performing fast approximate nearest neighbor searches in highdimensional spaces. Used in kdtree for fast approximate nearest neighborssearch.

• Visualization ToolKit (VTK) version >= 5.6.1 (http://www.vtk.org/)

  Software system for 3D computer graphics, image processing and visualization.Used in visualization for 3D point cloud rendering and visualization.

Optional

The following libraries are Optional and provide extended functionalitywithin PCL, ie Kinect support.

• Qhull version >= 2011.1 (http://www.qhull.org/)

  computes the convex hull, Delaunay triangulation, Voronoi diagram, halfspaceintersection about a point, furthest-site Delaunay triangulation, andfurthest-site Voronoi diagram. Used for convex/concave hull decompositionsin surface.

• libusb (http://www.libusb.org/)

  A library that gives user level applications uniform access to USB devicesacross many different operating systems.

• PCL Patched OpenNI/Sensor (http://www.openni.org/)

  The OpenNI Framework provides the interface for physical devices and formiddleware components. Used to grab point clouds from OpenNI compliantdevices.

Advanced (Developers)

The following libraries are Advanced and provide additional functionalityfor PCL developers:

• googletest version >= 1.6.0 (http://code.google.com/p/googletest/)

  Google’s framework for writing C++ tests on a variety of platforms. Usedto build test units.

• Doxygen (http://www.doxygen.org)

  A documentation system for C++, C, Java, Objective-C, Python, IDL (Corba andMicrosoft flavors), Fortran, VHDL, PHP, C#, and to some extent D.

• Sphinx (http://sphinx-doc.org/)

  A tool that makes it easy to create intelligent and beautifuldocumentation.

By now you should have downloaded and installed the latest versions of XCode andMacPorts under the Prerequisites section. We’ll be installing mostdependencies available via MacPorts and the rest will be built from source.

Install CMake

Install Boost

Install Eigen

Install FLANN

Install VTK

To install via MacPorts:

To install from source download the source fromhttp://www.vtk.org/VTK/resources/software.html

Follow the README.html for compiling on UNIX / Cygwin / Mac OSX:

Press [c] for initial configuration

Press [t] to get into advanced mode and change the following:

Note

VTK must be built with Cocoa support and must be installed,in order for the visualization module to be able to compile. If you donot require visualisation, you may omit this step.

Press [g] to generate the make files.

Press [q] to quit.

Then run:

Install Qhull

Install libusb

Install Patched OpenNI and Sensor

Download the patched versions of OpenNI and Sensor from the PCL downloads pagehttp://pointclouds.org/downloads/macosx.html

Extract, build, fix permissions and install OpenNI:

In addition the following primesense xml config found within the patched OpenNIdownload needs its permissions fixed and copied to the correct location to forthe Kinect to work on Mac OS X:

Extract, build, fix permissions and install Sensor:

At this point you should have everything needed installed to build PCL withalmost no additional configuration.

Checkout the PCL source from the Github:

Create the build directories, configure CMake, build and install:

The customization of the build process is out of the scope of this tutorial andis covered in greater detail in the Customizing the PCL build process tutorial.

We finally managed to compile the Point Cloud Library (PCL) for Mac OS X. Youcan start using them in your project by following the Using PCL in your own project tutorial.

API Documentation (Doxygen)

Install Doxygen via MacPorts:

Or install the Prebuilt binary for Mac OS X(http://www.stack.nl/~dimitri/doxygen/download.html#latestsrc)

After installed you can build the documentation:

Tutorials (Sphinx)

In addition to the API documentation there is also tutorial documentation builtusing Sphinx. The easiest way to get this installed is using pythonseasy_install:

The Sphinx documentation also requires the third party contrib extensionsphinxcontrib-doxylink (https://pypi.python.org/pypi/sphinxcontrib-doxylink)to reference the Doxygen built documentation.

Get To The Point Mac Os X

To install from source you’ll also need Mercurial:

After installed you can build the tutorials:

Note

Sphinx can be installed via MacPorts but is a bit of a pain getting all thePYTHON_PATH’s in order

Is your Mac up to date with the latest version of the Mac operating system? Is it using the version required by a product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

From the Apple menu  in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Big Sur, followed by its version number. If you need to know the build number as well, click the version number to see it.

Which macOS version is the latest?

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Big Sur. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
