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.

###Features###

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

GUI

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

Sound

• 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)

Other

• 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)
