ZenGL - cross-platform game development library, designed to provide necessary functionality for rendering 2D-graphics, handling input, sound output, etc.

• License: zlib
• Supported OS: GNU/Linux, Windows, MacOS X, iOS, Android 2.1+
• Supported compilers: FreePascal, Delphi
• Graphics API: OpenGL, OpenGL ES 1.x, Direct3D 8/9

• Sound API: OpenAL, DirectSound

• Main

  • can be used as so/dll/dylib or statically compiled with your application
  • rendering to own or any other prepared window
  • logging
  • resource loading from files, memory and zip archives
  • multithreaded resource loading
  • easy way to add support for new resource format
• Configuration of
  • antialiasing, screen resolution, refresh rate and vertical synchronization
  • aspect correction
  • title, position and size of window
  • cursor visibility in window space
• Input
  • handling keyboard, mouse and joystick input
  • handling of Unicode text input
  • possibility to restrict the input to the Latin alphabet
• Textures
  • supports tga, png and jpg
  • correct work with NPOT textures
  • control the filter parameters
  • masking
  • render targets for rendering into texture
• Text
  • textured Unicode-font
  • rendering UTF-8 text
  • rendering text with alignment and other options like size, color and count of symbols
• 2D-subsystem
  • batch render for high-speed rendering
  • rendering different primitives
  • sprite engine
  • rendering static and animated sprites and tiles
  • rendering distortion grid
  • rendering sprites with new texture coordinates(with the pixel dimension and the usual 0..1)
  • control the blend mode and color mix mode
  • control the color and alpha of vertices of sprites and primitives
  • additional sprite transformations(flipping, zooming, vertices offset)
  • fast clipping of invisible sprites
  • 2D camera with ability to zoom and rotate the scene
• Sound
  • works through OpenAL or DirectSound, depends on configuration or OS
  • correct work without soundcard
  • supports wav and ogg as sound samples
  • playing ogg files in separate thread
  • control the volume and playback speed
  • moving sound sources in 3D space
• Video
  • decoding video frames into texture
  • supports theora codec in ogv container
• Mathematic
  • basic set of additional math functions
  • triangulation functions
  • basic set of collision functions
• Additional
  • reading and writing ini-files
  • functions for work with files and memory
