GLPT :: OpenGL Pascal Toolkit
An easy to use native pascal toolkit that allows to create and manage OpenGL contexts in a platform independent way. GLPT is available under the MIT license.
Usage
Using GLPT is easy, you only need to include the GLPT unit and create a window. Then run the event loop and do all your application stuff there. There are numerous examples included to help you to make a jump start.
uses
GLPT;
...
GLPT_Init;
window := GLPT_CreateWindow(0, 0, width, height, 'Simple example');
while not GLPT_WindowShouldClose(window) do
begin
//do your application and OpenGL magic here
GLPT_SwapBuffers(window);
GLPT_PollEvents;
end;
GLPT_Terminate;

Design considerations
GLPT is planned to be a simple and easy to use library. When working on the code please consider the following;
- flat API, so no classes and no objects
- no external dependencies are allowed, also adding FPC units should be considered carefully
- only OpenGL context handling, no audio, font or UI included to name a few
