QGLViewer allows people programming in OpenGL to play around with three dimensional scenes or to write software that uses OpenGL. It provides a set of classes for camera control, as well as comfortable user interface that allows you to control your viewing parameters via mouse and buttons. A framework for camera paths and their interpolation is provided, as is a simple scene tree. QGLViewer is object oriented and programmed in C++ such that the programmer simply instantiates a viewer and connects it to their own render routines.
Tic-tac-toe is an OpenGL game that focuses on graphical effects, specifically realistic 3D rendering of water. The water surface is procedurally generated, and the pieces float realistically on top of it. The water is textured, blended, and environment mapped. It is fully refracted and incorporates the Fresnel term for opacity.
KIO-POV is a KDE IO-Slave for the Persistence of Vision Raytracer (POV-Ray). It can be used to render POV-Ray scenes and access the render results from Konqueror or other KDE programs without fiddling with the command line. Viewing render logs, scene information, and information about the POV- Ray configuration is possible as well.
