Fractal planet and terrain generator
Interactive application to generate and view random fractal planets andterrain with oceans, mountains, icecaps and rivers, then export them toPOV-Ray format or Blender. Written in C++ using Qt and OpenGL.
GLT OpenGL C++ Toolkit
GLT is a C++ class library for programming interactive 3D graphics with OpenGL.
GLFW
GLFW is a portable framework for OpenGL application development. Ithandles operating system specific tasks such OpenGL window management,resolution switching, keyboard, mouse and joystick input, timer input,creating threads, and more.
FFFF - Fast Floating Fractal Fun

Klimt
Klimt (formerly known as SoftGL) is a 3D library with a similiar API tothat of OpenGL and OpenGL|ES, targeted for mobile devices. We aresearching for developers. If you want to join send an email to theproject leader.
pdnmesh Finite Element program
An automatic 2D Delaunay mesh generator and solver for Finite ElementAnalysis. Can solve 2D field problems (Poisson and HelmholtzEquations). Can use LAPACK/ARPACK solvers producing OpenGL/Postscriptoutput. Uses C/GTK/GTKGLExt/MFC. Runs on Win32/Unix.
Inventor
LGPL Open Inventor (tm) C++ API using OpenGL from original SGI source.Inventor is the standard API for developers of Windows, Linux, andother Unix 3D applications. Current version only works on Irix andLinux. Port in progress to other platforms.
Internet C++/Internet Virtual Machine
Internet C++/Internet Virtual Machine is a high-speed, open-sourcealternative to Java and .NET. Applications written in standardlanguages, such as C and C++. OpenGL 1.2 support brings portablehigh-speed 3D graphics and games.
MathGL++
MathGL++ is a class library for fast C++ maths for use in OpenGL C++projects. Easy to use and similar to the OpenGL API. Matricies,Vectors, Quaternions, Linear polynomials with eigen systems are allgoing to be included.

GLI is a multi-platform, hardware-accelerated userinterface and animation engine powered by OpenGL. With GLI, realtime compositing of animated, high resolution images and movies is now possible on consumer PC hardware.
GL++ (opengl C++ wrapper)
This encapsulates some of the higher level functions of OpenGL usingextensions into C++ objects. These at the moment in time areframebuffer objects and shaders
