GLT OpenGL C++ Toolkit 0.7 project contains classes and routines for programming interactive 3D graphics with OpenGL.
The aim of Glt is to augment the OpenGL API with convenient mechanisms for manipulating the OpenGL state machine.
Glt is a work in progress, and by no means covers the entire OpenGL specification. However, it already includes several useful classes and is designed so that additional classes can be added easily. In addition to Glt, the GlutMaster classes provide C++ wrappers for the GLUT API.
Main features:
- GltFrameBuffer
- Read and write from frame buffer
- Save to PPM, TGA, BMP or PNG image files
- GltFrameBufferRGB
- GltFrameBufferZ
- GltFrameBufferStencil
- GltColor
- RGBA Color
- Over 600 predefined colors
- Color interpolation and arithmetic
- GltTexture
- Read from PPM, TGA, BMP or PNG image files
- Automatic texture binding
- Support for compressed compiled textures
- Support for procedural textures
- GltFont
- GltFontAscii Bitmapped ASCII font. Ten fonts included.
- GltFontUnicode Bitmapped Unicode font. Includes English, Chinese, Japanese and Korean.
- Vector, Matrix, Plane and BoundingBox
- Vector math functions: dot and cross products and arithmetic
- Transformation matrices, inverse, transpose and determinant
- Plane equation evaluation, ray-plane intersection
- Full OpenGL integration
- Random Number Generation
- GltRandomLCG Park and Miller LCG generator
- GltRandomLFSRMix Linear Feedback Shift Register generator
- GltRandomDouble, GltRandomInteger with configurable range
- GltRandomSphere point-on-sphere generator
- GltRandomOrientation orientation frame generator
- GltLight OpenGL Light Source.
- GltLightModel OpenGL Lighting Model.
- GltMaterial OpenGL Material Settings.
- OpenGL Matrix Manipulation
- GltOrtho Orthographic Projection.
- GltTextOverlay Text-box overlay.
- GltViewport Viewport settings.
- GltShape Scenegraph node class
- Transformation matrix
- Predefined shapes: GlutSphere,GlutCube,GlutCylinder, etc...
- GltShapes container class

3D Python OpenGL Chess Game project is a 3D chess game in Python with OpenGL.

3D Python OpenGL Chess Game is a normal chess game that has no computer player (yet). You can play against a friend on your PC.

While Digikam is a great app for managing your images, it lacks a good and fast image viewer in my opinion. Unfortunately, the fastest image viewer for KDE, Kuickshow, is not available as KIPI plugin. Therefore I wrote this plugin to fill that gap
Main features:
- works as KIPI plugin
- fast image loading (about as fast as kuickshow)
- fast zooming/panning (faster than kuickshow)

OGLTK (ogle-tic) is an OpenGL toolkit for GTK. This library gives programmers a very easy to use api to create amazing 3D applications. (Eg. Games, CAD)
OGLTK gives the programmer:
- OpenGL GTK Widget .
- A Scene object - Handles lighting and objects
- Lightsources
- Abstract 3D object class (GLobject)
- 3D Objects (Cube, Box and Gear, Cylinder, Disk, Sphere, Triangle) - Great examples of how to use the GLobject base class

OglExt is a free OpenGL extension library, enabling the easy access of all functionality up to OpenGL version 2.0 as well as API functions of more than 270 OpenGL extensions. OglExt library was initially written for Microsoft Windows but works for Linux and MacOS X as well.
OpenGL developers for the Windows operating system usually know the problem: The official OpenGL library only supports version 1.1 of the OpenGL specification. However, todays graphics hardware supports OpenGL version 2.0 and a lot OpenGL extensions. To access such functionality, you have to determine the entry point for each function you want to use via wglGetProcAddress() or glXGetProcAddressARB(). Even worse, for Microsoft Windows you have to do this for each OpenGL rendering context, because the entry points may differ for different pixel formats.
By using OglExt, you dont have to care about this anymore, because the extension library manages all the above for over 200 OpenGL extensions.
Enhancements:
- This release fixes a minor bug in the parsing of functions that have pointers as return types.
- Additionally, the project compiles on Visual Studio .NET 2005.

bengsaver is a screensaver for KDE. It shows bouncing balls or bee swarms, with collision detection.
Enhancements:
- added OpenGL frontend for drawing 3D balls
