================== Pyrit Ray Tracer==================File Organization-----------------/build -- output directory for binaries and other generated files/ccdemos -- ray tracer demos in C++/demos -- ray tracer demos in Python/docs -- Doxygen generated documentation/include -- header files/models -- common models for use by demos/src -- ray tracing library source code/tests -- test programs for classes/tools -- auxiliary programsClasses organization throughout header files is explained in DEVNOTES.Building--------Type 'scons pyrit' to build and 'scons -h' for list of targets.Requirements: SCons pthreads (see bellow) libpng, zlib Python 2.4 or newer for Python module and demos SDL for interactive C++ demosIt should build with these compilers: GCC, IntelC, MSVCGCC is default in Linux, MSVC is default in Windows.Downloading model files-----------------------Not all models are included in distribution. To download the largeStanford models, type 'scons download-models', which will downloadend extract the archives to appropriate location.The download script uses 'tar' and 'wget' utilities.For Windows, these are available here:http://gnuwin32.sourceforge.net/packages/wget.htmhttp://gnuwin32.sourceforge.net/packages/libarchive.htmPthreads--------Threads can be used to render rays paralelly. Arbitrary numberof threads can be used.For Windows, get Pthreads library here:http://sources.redhat.com/pthreads-win32/License-------This software is published under terms of MIT license.See COPYING for full text of license.Website-------Latest version can be obtained at http://wiki.fiction.cz/Pyrit
