-===========
 
 [![Build Status](https://travis-ci.org/thunderk/paysages3d.png)](https://travis-ci.org/thunderk/paysages3d)
 
-About
+
------
+## About
 
 [Paysages 3D](http://www.paysages3d.com) is a work-in-progress landscape generator, modeler and renderer software.
 
-It is written in C++ 11, using Qt 5.2 as only dependency.
+It is written in C++ 11, using Qt 5.2 as only dependency (and Google Test for unit testing).
 
 [![Screenshot 1](data/screenshots/small1.jpg)](data/screenshots/large1.jpg) [![Screenshot 2](data/screenshots/small2.jpg)](data/screenshots/large2.jpg) [![Screenshot 3](data/screenshots/small3.jpg)](data/screenshots/large3.jpg)
 
-Build/Run
----------
 
-At the moment, the build system is only well tested using the latest [QtSDK](http://qt-project.org/downloads) installation, and [QtCreator](http://qt-project.org/downloads#qt-creator). Later work will remove this dependency.
+## Build/Run
 
-Simply open the *src/paysages.pro* file in QtCreator, and make a shadow build.
+### Using QtSDK (All platforms)
 
-You can then run the compiled program **from the top project directory** (the one that contains *src* and *data*).
+Download and install the latest [QtSDK](http://qt-project.org/downloads).
 
-Licensing
+Launch QtCreator, and open the project file *src/paysages.pro*.
----------
+
+Go to the "Projects" tab to edit the directory in which the executable will be run, and set **the top project directory** (the one that contains *src* and *data*). If you don't do this, some data files will not be found.
+
+### Using a packaged Qt (Linux)
+
+You need at least the 5.2 packaged version of Qt, with qMake and QtCore, QtGui and QtOpengl modules.
+
+On Ubuntu/Mint:
+
+    sudo apt-get install qt5-qmake libqt5core5a libqt5gui5 libqt5widgets5 libqt5opengl5-dev
+
+Then to build and run the software:
+
+    make run
+
+### Unit tests
+
+Running the unit tests needs the Google Test framework:
+
+    git submodule init
+    git submodule update
+
+Then build and run the tests:
+
+    make tests
+
+If you're using QtCreator, you can run the "tests" executable, not forgetting to change the directory in which the executable is run.

src/tests/googletest/CHANGES

@@ -1,157 +0,0 @@
-Changes for 1.7.0:
-
-* New feature: death tests are supported on OpenBSD and in iOS
-  simulator now.
-* New feature: Google Test now implements a protocol to allow
-  a test runner to detect that a test program has exited
-  prematurely and report it as a failure (before it would be
-  falsely reported as a success if the exit code is 0).
-* New feature: Test::RecordProperty() can now be used outside of the
-  lifespan of a test method, in which case it will be attributed to
-  the current test case or the test program in the XML report.
-* New feature (potentially breaking): --gtest_list_tests now prints
-  the type parameters and value parameters for each test.
-* Improvement: char pointers and char arrays are now escaped properly
-  in failure messages.
-* Improvement: failure summary in XML reports now includes file and
-  line information.
-* Improvement: the <testsuites> XML element now has a timestamp attribute.
-* Improvement: When --gtest_filter is specified, XML report now doesn't
-  contain information about tests that are filtered out.
-* Fixed the bug where long --gtest_filter flag values are truncated in
-  death tests.
-* Potentially breaking change: RUN_ALL_TESTS() is now implemented as a
-  function instead of a macro in order to work better with Clang.
-* Compatibility fixes with C++ 11 and various platforms.
-* Bug/warning fixes.
-
-Changes for 1.6.0:
-
-* New feature: ADD_FAILURE_AT() for reporting a test failure at the
-  given source location -- useful for writing testing utilities.
-* New feature: the universal value printer is moved from Google Mock
-  to Google Test.
-* New feature: type parameters and value parameters are reported in
-  the XML report now.
-* A gtest_disable_pthreads CMake option.
-* Colored output works in GNU Screen sessions now.
-* Parameters of value-parameterized tests are now printed in the
-  textual output.
-* Failures from ad hoc test assertions run before RUN_ALL_TESTS() are
-  now correctly reported.
-* Arguments of ASSERT_XY and EXPECT_XY no longer need to support << to
-  ostream.
-* More complete handling of exceptions.
-* GTEST_ASSERT_XY can be used instead of ASSERT_XY in case the latter
-  name is already used by another library.
-* --gtest_catch_exceptions is now true by default, allowing a test
-  program to continue after an exception is thrown.
-* Value-parameterized test fixtures can now derive from Test and
-  WithParamInterface<T> separately, easing conversion of legacy tests.
-* Death test messages are clearly marked to make them more
-  distinguishable from other messages.
-* Compatibility fixes for Android, Google Native Client, MinGW, HP UX,
-  PowerPC, Lucid autotools, libCStd, Sun C++, Borland C++ Builder (Code Gear),
-  IBM XL C++ (Visual Age C++), and C++0x.
-* Bug fixes and implementation clean-ups.
-* Potentially incompatible changes: disables the harmful 'make install'
-  command in autotools.
-
-Changes for 1.5.0:
-
- * New feature: assertions can be safely called in multiple threads
-   where the pthreads library is available.
- * New feature: predicates used inside EXPECT_TRUE() and friends
-   can now generate custom failure messages.
- * New feature: Google Test can now be compiled as a DLL.
- * New feature: fused source files are included.
- * New feature: prints help when encountering unrecognized Google Test flags.
- * Experimental feature: CMake build script (requires CMake 2.6.4+).
- * Experimental feature: the Pump script for meta programming.
- * double values streamed to an assertion are printed with enough precision
-   to differentiate any two different values.
- * Google Test now works on Solaris and AIX.
- * Build and test script improvements.
- * Bug fixes and implementation clean-ups.
-
- Potentially breaking changes:
-
- * Stopped supporting VC++ 7.1 with exceptions disabled.
- * Dropped support for 'make install'.
-
-Changes for 1.4.0:
-
- * New feature: the event listener API
- * New feature: test shuffling
- * New feature: the XML report format is closer to junitreport and can
-   be parsed by Hudson now.
- * New feature: when a test runs under Visual Studio, its failures are
-   integrated in the IDE.
- * New feature: /MD(d) versions of VC++ projects.
- * New feature: elapsed time for the tests is printed by default.
- * New feature: comes with a TR1 tuple implementation such that Boost
-   is no longer needed for Combine().
- * New feature: EXPECT_DEATH_IF_SUPPORTED macro and friends.
- * New feature: the Xcode project can now produce static gtest
-   libraries in addition to a framework.
- * Compatibility fixes for Solaris, Cygwin, minGW, Windows Mobile,
-   Symbian, gcc, and C++Builder.
- * Bug fixes and implementation clean-ups.
-
-Changes for 1.3.0:
-
- * New feature: death tests on Windows, Cygwin, and Mac.
- * New feature: ability to use Google Test assertions in other testing
-   frameworks.
- * New feature: ability to run disabled test via
-   --gtest_also_run_disabled_tests.
- * New feature: the --help flag for printing the usage.
- * New feature: access to Google Test flag values in user code.
- * New feature: a script that packs Google Test into one .h and one
-   .cc file for easy deployment.
- * New feature: support for distributing test functions to multiple
-   machines (requires support from the test runner).
- * Bug fixes and implementation clean-ups.
-
-Changes for 1.2.1:
-
- * Compatibility fixes for Linux IA-64 and IBM z/OS.
- * Added support for using Boost and other TR1 implementations.
- * Changes to the build scripts to support upcoming release of Google C++
-   Mocking Framework.

-Google C++ Testing Framework
-============================
-
-http://code.google.com/p/googletest/
-
-Overview
---------
-
-Google's framework for writing C++ tests on a variety of platforms
-(Linux, Mac OS X, Windows, Windows CE, Symbian, etc).  Based on the
-xUnit architecture.  Supports automatic test discovery, a rich set of
-assertions, user-defined assertions, death tests, fatal and non-fatal
-failures, various options for running the tests, and XML test report
-generation.
-
-Please see the project page above for more information as well as the
-mailing list for questions, discussions, and development.  There is
-also an IRC channel on OFTC (irc.oftc.net) #gtest available.  Please
-join us!
-
-Requirements for End Users
---------------------------
-
-Google Test is designed to have fairly minimal requirements to build
-and use with your projects, but there are some.  Currently, we support
-Linux, Windows, Mac OS X, and Cygwin.  We will also make our best
-effort to support other platforms (e.g. Solaris, AIX, and z/OS).
-However, since core members of the Google Test project have no access
-to these platforms, Google Test may have outstanding issues there.  If
-you notice any problems on your platform, please notify
-googletestframework@googlegroups.com.  Patches for fixing them are
-even more welcome!
-
-### Linux Requirements ###
-
-These are the base requirements to build and use Google Test from a source
-package (as described below):
-  * GNU-compatible Make or gmake
-  * POSIX-standard shell
-  * POSIX(-2) Regular Expressions (regex.h)
-  * A C++98-standard-compliant compiler
-
-### Windows Requirements ###
-
-  * Microsoft Visual C++ 7.1 or newer
-
-### Cygwin Requirements ###
-
-  * Cygwin 1.5.25-14 or newer
-
-### Mac OS X Requirements ###
-
-  * Mac OS X 10.4 Tiger or newer
-  * Developer Tools Installed
-
-Also, you'll need CMake 2.6.4 or higher if you want to build the
-samples using the provided CMake script, regardless of the platform.
-
-Requirements for Contributors
------------------------------
-
-We welcome patches.  If you plan to contribute a patch, you need to
-build Google Test and its own tests from an SVN checkout (described
-below), which has further requirements:
-
-  * Python version 2.3 or newer (for running some of the tests and
-    re-generating certain source files from templates)
-  * CMake 2.6.4 or newer
-
-Getting the Source
-------------------
-
-There are two primary ways of getting Google Test's source code: you
-can download a stable source release in your preferred archive format,
-or directly check out the source from our Subversion (SVN) repositary.
-The SVN checkout requires a few extra steps and some extra software
-packages on your system, but lets you track the latest development and
-make patches much more easily, so we highly encourage it.
-
-### Source Package ###
-
-Google Test is released in versioned source packages which can be
-downloaded from the download page [1].  Several different archive
-formats are provided, but the only difference is the tools used to
-manipulate them, and the size of the resulting file.  Download
-whichever you are most comfortable with.
-
-  [1] http://code.google.com/p/googletest/downloads/list
-
-Once the package is downloaded, expand it using whichever tools you
-prefer for that type.  This will result in a new directory with the
-name "gtest-X.Y.Z" which contains all of the source code.  Here are
-some examples on Linux:
-
-  tar -xvzf gtest-X.Y.Z.tar.gz
-  tar -xvjf gtest-X.Y.Z.tar.bz2
-  unzip gtest-X.Y.Z.zip
-
-### SVN Checkout ###
-
-To check out the main branch (also known as the "trunk") of Google
-Test, run the following Subversion command:
-
-  svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn
-
-Setting up the Build
---------------------
-
-To build Google Test and your tests that use it, you need to tell your
-build system where to find its headers and source files.  The exact
-way to do it depends on which build system you use, and is usually
-straightforward.
-
-### Generic Build Instructions ###
-
-Suppose you put Google Test in directory ${GTEST_DIR}.  To build it,
-create a library build target (or a project as called by Visual Studio
-and Xcode) to compile
-
-  ${GTEST_DIR}/src/gtest-all.cc
-
-with ${GTEST_DIR}/include in the system header search path and ${GTEST_DIR}
-in the normal header search path.  Assuming a Linux-like system and gcc,
-something like the following will do:
-
-  g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-      -pthread -c ${GTEST_DIR}/src/gtest-all.cc
-  ar -rv libgtest.a gtest-all.o
-
-(We need -pthread as Google Test uses threads.)
-
-Next, you should compile your test source file with
-${GTEST_DIR}/include in the system header search path, and link it
-with gtest and any other necessary libraries:
-
-  g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \
-      -o your_test
-
-As an example, the make/ directory contains a Makefile that you can
-use to build Google Test on systems where GNU make is available
-(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
-Test's own tests.  Instead, it just builds the Google Test library and
-a sample test.  You can use it as a starting point for your own build
-script.
-
-If the default settings are correct for your environment, the
-following commands should succeed:
-
-  cd ${GTEST_DIR}/make
-  make
-  ./sample1_unittest
-
-If you see errors, try to tweak the contents of make/Makefile to make
-them go away.  There are instructions in make/Makefile on how to do
-it.
-
-### Using CMake ###
-
-Google Test comes with a CMake build script (CMakeLists.txt) that can
-be used on a wide range of platforms ("C" stands for cross-platofrm.).
-If you don't have CMake installed already, you can download it for
-free from http://www.cmake.org/.
-
-CMake works by generating native makefiles or build projects that can
-be used in the compiler environment of your choice.  The typical
-workflow starts with:
-
-  mkdir mybuild       # Create a directory to hold the build output.
-  cd mybuild
-  cmake ${GTEST_DIR}  # Generate native build scripts.
-
-If you want to build Google Test's samples, you should replace the
-last command with
-
-  cmake -Dgtest_build_samples=ON ${GTEST_DIR}
-
-If you are on a *nix system, you should now see a Makefile in the
-current directory.  Just type 'make' to build gtest.
-
-If you use Windows and have Vistual Studio installed, a gtest.sln file
-and several .vcproj files will be created.  You can then build them
-using Visual Studio.
-
-On Mac OS X with Xcode installed, a .xcodeproj file will be generated.
-
-### Legacy Build Scripts ###
-
-Before settling on CMake, we have been providing hand-maintained build
-projects/scripts for Visual Studio, Xcode, and Autotools.  While we
-continue to provide them for convenience, they are not actively
-maintained any more.  We highly recommend that you follow the
-instructions in the previous two sections to integrate Google Test
-with your existing build system.
-
-If you still need to use the legacy build scripts, here's how:
-
-The msvc\ folder contains two solutions with Visual C++ projects.
-Open the gtest.sln or gtest-md.sln file using Visual Studio, and you
-are ready to build Google Test the same way you build any Visual
-Studio project.  Files that have names ending with -md use DLL
-versions of Microsoft runtime libraries (the /MD or the /MDd compiler
-option).  Files without that suffix use static versions of the runtime
-libraries (the /MT or the /MTd option).  Please note that one must use
-the same option to compile both gtest and the test code.  If you use
-Visual Studio 2005 or above, we recommend the -md version as /MD is
-the default for new projects in these versions of Visual Studio.
-
-On Mac OS X, open the gtest.xcodeproj in the xcode/ folder using
-Xcode.  Build the "gtest" target.  The universal binary framework will
-end up in your selected build directory (selected in the Xcode
-"Preferences..." -> "Building" pane and defaults to xcode/build).
-Alternatively, at the command line, enter:
-
-  xcodebuild
-
-This will build the "Release" configuration of gtest.framework in your
-default build location.  See the "xcodebuild" man page for more
-information about building different configurations and building in
-different locations.
-
-If you wish to use the Google Test Xcode project with Xcode 4.x and
-above, you need to either:
- * update the SDK configuration options in xcode/Config/General.xconfig.
-   Comment options SDKROOT, MACOS_DEPLOYMENT_TARGET, and GCC_VERSION. If
-   you choose this route you lose the ability to target earlier versions
-   of MacOS X.
- * Install an SDK for an earlier version. This doesn't appear to be
-   supported by Apple, but has been reported to work
-   (http://stackoverflow.com/questions/5378518).
-
-Tweaking Google Test
---------------------
-
-Google Test can be used in diverse environments.  The default
-configuration may not work (or may not work well) out of the box in
-some environments.  However, you can easily tweak Google Test by
-defining control macros on the compiler command line.  Generally,
-these macros are named like GTEST_XYZ and you define them to either 1
-or 0 to enable or disable a certain feature.
-
-We list the most frequently used macros below.  For a complete list,
-see file include/gtest/internal/gtest-port.h.
-
-### Choosing a TR1 Tuple Library ###
-
-Some Google Test features require the C++ Technical Report 1 (TR1)
-tuple library, which is not yet available with all compilers.  The
-good news is that Google Test implements a subset of TR1 tuple that's
-enough for its own need, and will automatically use this when the
-compiler doesn't provide TR1 tuple.
-
-Usually you don't need to care about which tuple library Google Test
-uses.  However, if your project already uses TR1 tuple, you need to
-tell Google Test to use the same TR1 tuple library the rest of your
-project uses, or the two tuple implementations will clash.  To do
-that, add
-
-  -DGTEST_USE_OWN_TR1_TUPLE=0
-
-to the compiler flags while compiling Google Test and your tests.  If
-you want to force Google Test to use its own tuple library, just add
-
-  -DGTEST_USE_OWN_TR1_TUPLE=1
-
-to the compiler flags instead.
-
-If you don't want Google Test to use tuple at all, add
-
-  -DGTEST_HAS_TR1_TUPLE=0
-
-and all features using tuple will be disabled.
-
-### Multi-threaded Tests ###
-
-Google Test is thread-safe where the pthread library is available.
-After #include "gtest/gtest.h", you can check the GTEST_IS_THREADSAFE
-macro to see whether this is the case (yes if the macro is #defined to
-1, no if it's undefined.).
-
-If Google Test doesn't correctly detect whether pthread is available
-in your environment, you can force it with
-
-  -DGTEST_HAS_PTHREAD=1
-
-or
-
-  -DGTEST_HAS_PTHREAD=0
-
-When Google Test uses pthread, you may need to add flags to your
-compiler and/or linker to select the pthread library, or you'll get
-link errors.  If you use the CMake script or the deprecated Autotools
-script, this is taken care of for you.  If you use your own build
-script, you'll need to read your compiler and linker's manual to
-figure out what flags to add.
-
-### As a Shared Library (DLL) ###
-
-Google Test is compact, so most users can build and link it as a
-static library for the simplicity.  You can choose to use Google Test
-as a shared library (known as a DLL on Windows) if you prefer.
-
-To compile *gtest* as a shared library, add
-
-  -DGTEST_CREATE_SHARED_LIBRARY=1
-
-to the compiler flags.  You'll also need to tell the linker to produce
-a shared library instead - consult your linker's manual for how to do
-it.
-
-To compile your *tests* that use the gtest shared library, add
-
-  -DGTEST_LINKED_AS_SHARED_LIBRARY=1
-
-to the compiler flags.
-
-Note: while the above steps aren't technically necessary today when
-using some compilers (e.g. GCC), they may become necessary in the
-future, if we decide to improve the speed of loading the library (see
-http://gcc.gnu.org/wiki/Visibility for details).  Therefore you are
-recommended to always add the above flags when using Google Test as a
-shared library.  Otherwise a future release of Google Test may break
-your build script.
-
-### Avoiding Macro Name Clashes ###
-
-In C++, macros don't obey namespaces.  Therefore two libraries that
-both define a macro of the same name will clash if you #include both
-definitions.  In case a Google Test macro clashes with another
-library, you can force Google Test to rename its macro to avoid the
-conflict.
-
-Specifically, if both Google Test and some other code define macro
-FOO, you can add
-
-  -DGTEST_DONT_DEFINE_FOO=1
-
-to the compiler flags to tell Google Test to change the macro's name
-from FOO to GTEST_FOO.  Currently FOO can be FAIL, SUCCEED, or TEST.
-For example, with -DGTEST_DONT_DEFINE_TEST=1, you'll need to write
-
-  GTEST_TEST(SomeTest, DoesThis) { ... }
-
-instead of
-
-  TEST(SomeTest, DoesThis) { ... }
-
-in order to define a test.
-
-Upgrating from an Earlier Version
----------------------------------
-
-We strive to keep Google Test releases backward compatible.
-Sometimes, though, we have to make some breaking changes for the
-users' long-term benefits.  This section describes what you'll need to
-do if you are upgrading from an earlier version of Google Test.
-
-### Upgrading from 1.3.0 or Earlier ###
-
-You may need to explicitly enable or disable Google Test's own TR1
-tuple library.  See the instructions in section "Choosing a TR1 Tuple
-Library".
-
-### Upgrading from 1.4.0 or Earlier ###
-
-The Autotools build script (configure + make) is no longer officially
-supportted.  You are encouraged to migrate to your own build system or
-use CMake.  If you still need to use Autotools, you can find
-instructions in the README file from Google Test 1.4.0.
-
-On platforms where the pthread library is available, Google Test uses
-it in order to be thread-safe.  See the "Multi-threaded Tests" section
-for what this means to your build script.
-
-If you use Microsoft Visual C++ 7.1 with exceptions disabled, Google
-Test will no longer compile.  This should affect very few people, as a
-large portion of STL (including <string>) doesn't compile in this mode
-anyway.  We decided to stop supporting it in order to greatly simplify
-Google Test's implementation.
-
-Developing Google Test
-----------------------
-
-This section discusses how to make your own changes to Google Test.
-
-### Testing Google Test Itself ###
-
-To make sure your changes work as intended and don't break existing
-functionality, you'll want to compile and run Google Test's own tests.
-For that you can use CMake:
-
-  mkdir mybuild
-  cd mybuild
-  cmake -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Make sure you have Python installed, as some of Google Test's tests
-are written in Python.  If the cmake command complains about not being
-able to find Python ("Could NOT find PythonInterp (missing:
-PYTHON_EXECUTABLE)"), try telling it explicitly where your Python
-executable can be found:
-
-  cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
-
-Next, you can build Google Test and all of its own tests.  On *nix,
-this is usually done by 'make'.  To run the tests, do
-
-  make test
-
-All tests should pass.
-
-### Regenerating Source Files ###
-
-Some of Google Test's source files are generated from templates (not
-in the C++ sense) using a script.  A template file is named FOO.pump,
-where FOO is the name of the file it will generate.  For example, the
-file include/gtest/internal/gtest-type-util.h.pump is used to generate
-gtest-type-util.h in the same directory.
-
-Normally you don't need to worry about regenerating the source files,
-unless you need to modify them.  In that case, you should modify the
-corresponding .pump files instead and run the pump.py Python script to
-regenerate them.  You can find pump.py in the scripts/ directory.
-Read the Pump manual [2] for how to use it.
-
-  [2] http://code.google.com/p/googletest/wiki/PumpManual
-
-### Contributing a Patch ###
-
-We welcome patches.  Please read the Google Test developer's guide [3]
-for how you can contribute.  In particular, make sure you have signed
-the Contributor License Agreement, or we won't be able to accept the
-patch.
