GLScene
GLSceneFree outdoor graphics library based on the OpenGL for Delphi and Lazarus, originally developed in 1999, Mike �����. With version 0.5 Development of the GLScene was continued by Eric �������, and since 2006, the library is supported by a community of programrs, including Russia.
GLScene is continuously evolving, adapting to modern technology of 3D graphics. In addition to the graphics classes and components, the library provides tools for working with sound, I/O, the game logic and physics.
The high-level structure of the GLScene allows beginners to create games, not knowing any OpenGL commands, not presenting, as the matrix are multiplied together and how to write shaders. At the same time, professionals offering all the possibilities for the use of pure OpenGL, where necessary, modifying the source code under themselves and create professional applications.
On the basis of the modified the source code GLScene is built Xtreme3D.
