| == Introduction to SDL == === What is SDL? === The Simple !DirectMedia Layer library (SDL) is a general API that provides low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D framebuffer across multiple platforms. |

| The current version (1.3) supports Windows, Windows CE, Mac OS X, Linux, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, and QNX. The code contains support for other operating systems but those are not officially supported. SDL is written in C, but works with C++ natively, and has bindings to several other languages, including Ada, C#, Eiffel, Erlang, Euphoria, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP, Pike, Pliant, Python, Ruby, and Smalltalk. This library is distributed under GNU LGPL [<- link to licensing info] version 2. This license allows you to use SDL freely in commercial programs as long as you link with the dynamic library. A full commercial license for SDL 1.3 is available from [[http://www.galaxygameworks.com|Galaxy Gameworks]]. === What can SDL do? === ''''' Video''''' * Set a video mode at any depth (8-bpp or greater) with optional conversion, if the video mode is not supported by the hardware * Write directly to a linear graphics framebuffer * Create surfaces with colorkey or alpha blending attributes * Surface blits are automatically converted to the target format using optimized blitters and are hardware accelerated, when possible. MMX optimized blits are available for the x86 * Hardware accelerated blit and fill operations are used if supported by the hardware * Window Management * Rendering ''''' Input''''' * Events provided for: * Application visibility changes * Keyboard input * Mouse input * Joystick input * User-requested quit * Each event can be enabled or disabled with SDL_!EventState() * Events are passed through a user-specified filter function before being posted to the internal event queue * Thread-safe event queue ''''' Force Feedback''''' * Force feedback is supported under Windows, Mac OSX and Linux '''''Audio''''' * Set audio playback of 8-bit and 16-bit audio, mono or stereo, with optional conversion if the format is not supported by the hardware * Audio runs independently in a separate thread, filled via a user callback mechanism * Designed for custom software audio mixers, but the example archive contains a complete audio/music output library '''''File I/O Abstraction''''' * General purpose abstraction for opening, reading and writing data * Built-in support for files and memory '''''Shared Object Support''''' * Load shared objects (DLL on Windows, .dylib on Mac OSX, .so on Linux) * Lookup functions in shared objects '''''Threads''''' * Simple thread creation API * Simple binary semaphores for synchronization '''''Timers''''' * Get the number of milliseconds elapsed * Wait a specified number of milliseconds * Set a single periodic timer with 10ms resolution '''''CPU Feature Detection''''' * Detect MMX, SSE, 3DNow and AltiVec CPU features '''''Power Management''''' * Querying power management status '''''Endian Independence''''' * Detect the endianness of the current system * Routines for fast swapping of data values * Read and write data of a specified endianness === What platforms does SDL run on? === '''''Windows''''' * Two versions, one safe for all systems based on Win32 APIs, and one with higher performance, based on DirectX APIs * Safe version uses GDI for video display. High performance version uses !Direct3D for video display, taking advantage of modern hardware acceleration * Safe version uses waveOut APIs for sound. High performance version uses !DirectSound for audio playback '''''Mac OSX''''' * Uses Cocoa for video display, taking advantage of OpenGL for hardware acceleration * Uses Core Audio for sound '''''Linux''''' * Uses X11 for video display, taking advantage of OpenGL for hardware acceleration * Uses the ALSA, OSS and !PulseAudio APIs for sound == Special features in SDL 1.3 == * Full 3D hardware acceleration * Support for OpenGL 3.0+ * Support for multiple windows * Support for multiple displays * Support for multiple mice, tablets, etc. * Force Feedback available on Windows, Mac OS X and Linux This wiki is powered by [[http://moinmo.in/|MoinMoin]]. |
