+- Notes for Linux
+------------------
+
+- Para o cmake reconhecer o Qt5 que não esteja instalado no sistema 
+e sim em um diretório do usuário, é necessário rodar o cmake desta maneira:
+
+$ CMAKE_PREFIX_PATH=~/Applications/Qt5/5.5/gcc_64/lib/cmake/ cmake ../core
+
+
+- Para executar os testes as libs do Qt5 devem estar visíveis para o sistema.
+Então, basta executar o seguinte comando:
+ 
+$ export LD_LIBRARY_PATH=~/Applications/Qt5/5.5/gcc_64/lib
+
+
+
+- Notes for Mac OS
+-------------------
+
+- Have HomeBrew and Qt installed
+
+- Add to your .profile:
+
+export PATH=$PATH:/Programs/Devel/Qt/5.5/clang_64/bin/
+
+
+- Install GLEW with HomeBrew:
+
+$ brew install glew
+

+
+S3D/Core Software
+=================
+
+
+This is the companion software package of the book
+"Design and Implementation of 3D Graphics Systems" 
+by Luiz Velho and Jonas Gomes and Mario Sousa.
+
+The software contains an implementation of all the
+algorithms described in the book.
+
+
+CONTENTS
+--------
+
+The directory hierarchy structure is as follows:
+
+./s3d
+     /core      - Linux relatead source code
+     /data      - Data files
+     /test      - Test scripts
+     /platforms - Deployment
+     /build     - CMake build directory
+      
+./s3d/core
+     /base    - Source of the Base library
+     /proj    - Source of the Applications
+
+./s3d/data
+     /model   - Geometric Model
+     /scn     - 3D Scene Files
+     /pic     - Images
+
+./s3d/tst
+     /demo    - Scripts to Run the CPU demos
+     /gldemo  - Scripts to Run the GPU demos
+
+./s3d/platforms
+     /qt            - QT Creator projects
+     /linux/bin     - Executables
+     /linux/lib     - Libraries
+     /linux/include - Header files
+
+
+INSTALLATION
+------------
+
+To install the Linux software run these commands in the "build" directory
+    cmake ../core
+    make
+    make install
+
+This should generate, compile and install the libraries and applications.
+
+
+TESTING
+-------
+
+To play the CPU demos run the main shell in the demo directory
+  cd test/demo
+  sh run-all
+
+This will execute all applications with test data.
+
+To play the GPU demos run the main shell in the gldemo directory
+  cd tst/gldemo
+  sh run-new
+
+To complie and run the QT demo
+  cd platforms/qt/s3dgl
+Open the project s3dgl.pro with QtCreator
+  run s3dgl
+  drag and drop the files in platforms/qt/scenes
+
+
+COMPATIBILITY
+-------------
+
+This software was developed using GNU tools under the
+Linux operating system. It has also been ported to MacOS X 
+and it may compile in Windows using the Cygwin/MinGW environment.
+
+
+REQUIREMENTS
+------------
+
+The software needs the following development tools
+ cmake, sh, make, gcc, bison, flex.
+It uses the imaging library libpng.
+The OpenGL implementation requires GLEW, GLUT and GLSL 2.1,
+
+The QT Applications require Qt 5.4 or higher.
+
+
+REMARKS
+-------
+
+Please note that for QT Applications work properly under Linux
+the following environment variables have to be set as indicated below.
+ LANG=C
+ LC_NUMERIC=C
+
+In QtCreator, this can be set up using the selection:
+ Project -> Run Settings -> Build Environments
+
+
+UPDATES
