- 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
