###Development closed. Next iteration is tiny-glr###

glr — glrenderer

glrenderer — Delphi 2D game development framework (OpenGL, Bass, Box2D) for Windows platform.

###Showcase### [screenshots will be soon] All screenshots made from demos which are provided with full source code and assets

Delphi 2007 or higher is supported. Delphi 7 is not supported due to operator overloading used in Math unit.


Main + and -

  • No VCL, win32 api — Windows only
  • DLL with interfaces exported
  • OpenGL 1.1+, fixed function pipeline (yes, glBegin/glEnd. It's all about my laziness)
  • Lightweight

Graphics 2D

  • Scene graph
  • Sprites (position, scale, rotation, textures, color tint)
  • Blending
  • Bitmap fonts with runtime generation from .otf and .ttf files
  • Pivot points support including custom position
  • Texture atlas support
  • BMP 24/32, TGA 24/32 support (no PNG, sorry)

Graphics 3D

  • Almost removed


  • Selfmade simple GUI-system with:
  • Buttons and TextButtons
  • Checkboxes
  • Sliders


  • Little wrapper for Bass library

Physics — Box2D

  • "box2d-delphi" project support
  • Wrapper for World class
  • Functions for synchronise render and physic objects
  • Functions for easy physic objects create using render objects
  • Physic scale support (physics is calculated in other units, not pixels)


  • Math unit with vectors, matrices and some other things
  • Tween system
  • Cheetah Texture Atlas support
  • Async input

###Known ussues and facepalms###

  • No documentation and lack of comments in source code
  • Bitmap font generation uses fixed texture size due to laziness
  • Text has not alignment support
  • Particles were under development and located in utils module apart from engine library (in theory it's mean performance troubles, in practice you will have no real troubles with it)
You can’t perform that action at this time.
