Why developing multi-platform?
More distribution channels Pretty simple from a technical point of view Pretty cheap (working for the desktop market) Why not?

Why developing for Mac OS X?
In the 2009 the Mac market was a niche market, then...

Why developing for Linux?
Niche market Catalyst for different markets Full availability of tool/framework More dedicated website Supporting the rising of the platform

Commercial solutions
Engines: Torque, Unigine, Unity, … Professional products Documentation not always perfect High costs not affordable for all Controlled by productors and licenses
Davide Coppola – [email protected] – Lowpoly Studios
free/Open Source solutions
2D engines: Allegro, Clanib, Love, ... 3D engines: Crystal Space, Irrlitch, Ogre 3D, Panda 3D, … Multi-platform (desktop) Mostly oriented to rendering Long development times No commercial support
Davide Coppola – [email protected] – Lowpoly Studios
Custom solutions
Made with your project in mind, so flexible No needs to learn new (third-party) thechnologies No fixed costs Less dependent on third party technologies Give you more experience Developing proprietary technology
Davide Coppola – [email protected] – Lowpoly Studios
Proposed solution
Follows the Custom model C++ code Multi-platform: Windows, Mac, Linux Based on free/Open Source frameworks and libraries Custom, but be flexible...

Managing multi-platform code
Some low level code may depend on the specific platform Compile different files for each platform Use pre-processor directives
void FrameTimer::Start(){
m_fElapsed = 0.f;
#ifdef WIN32QueryPerformanceCounter(&m_T1);
#elsegettimeofday(&m_TV1, NULL);
#endif}
Davide Coppola – [email protected] – Lowpoly Studios
Coding for Windows
No changes needed when using MinGW + Cygwyn Some changes to low level system code when using VisualC++ Examples available on UNIX Application Migration Guide:

Coding for Mac Os X
#ifdef MAC#include "OpenAL/al.h"#include "OpenAL/alc.h"
#else#include "AL/al.h"#include "AL/alc.h"
#endif
Mac Os X follows the POSIX standard Only difference: path of the .h files used by the frameworks
