GLCanvas - Minimalistic rendering library

GLCanvas provides a minimalistic rendering API in the same vein as raylib or libGDX.

A simple program with GLCanvas:

program Test;
uses
  CThreads, GLCanvas;
const
  window_size_width = 600;
  window_size_height = 600;
var
  texture: TTexture;
begin
  SetupCanvas(window_size_width, window_size_height);
  texture := TTexture.Create('deer.png');
  while IsRunning do
    begin
      ClearBackground;
      DrawTexture(texture, RectMake(50, 50, texture.GetSize));
      SwapBuffers;
    end;
  QuitApp;
end.

Features:

• Flat procedural API
• Standard vector types and matrix math
• Texture loading (only supports PNG format currently)
• Bitmap and Freetype fonts
• Shaders (optional)
• Frame buffers (optional)
• GLUI for many common UI elements like windows, buttons etc...

Platforms:

• GLPT enable using -dPLATFORM_GLPT (GLPT is the default platform)
• SDL enable using -dPLATFORM_SDL

Installing on Windows:

• Download and install the latest release of SDL2 for mingw. For example at the time of writing this SDL2-devel-2.26.3-mingw.zip is most recent. See https://github.com/libsdl-org/SDL/releasess Copy the SDL2.dll from \SDL2-2.24.1\i686-w64-mingw32\bin into the directory which contains the compiled executable (Use i686 for if you're using the i386-win32 32-bit compiler).

• Download FreeType libraries from https://github.com/ubawurinna/freetype-windows-binariess Copy /release dll/win32/freetype.dll into the directory which contains the compiled executable.
