Kobldes makes it possible for the designer to model building information and uses POV-Ray for visualization. It is also programmed using the POV-Ray screen description language (SDL). The goal of is to create a fully functioning building information modeling and management tool for designing buildings. It currently allows the designer to accomplish basic tasks with building components such as building levels and spaces in the process of solving design problems. In the near future, it will compute and make available information about the building such as sizes/volumes (such as an area for painting in a particular room), requirement checks (e.g. spatial conformance), and Property checks (e.g. calculating the solar savings factor).
Reindeer is a C library for the rendering of virtual scenes, mainly in three dimensions. The library dynamically loads backend modules to do the rendering. Currently there is only a backend for OpenGL, but ideas for future backends are a raytracer and perhaps Direct3D. Any number of rendering contexts can live at the same time. Contexts are tied to a backend, and backends are automatically loaded and unloaded on demand. Resources are defined globally and can be used by any number of contexts at the same time, even in different backends. The main goal is to make it easier for developers to write applications that have many rendering contexts with shared resources and automatic state management. Another advantage is that the user can choose in which way a scene should be rendered without recompiling the application. For example, a scene could be rendered with a rasterizer like OpenGL at one point, and with a raytracer at another. Reindeer can also be used to get portable graphics output. Reindeer is not a scene-graph library or a game engine, but it can be used to implement them. It's still up to the application to create and manage the native contexts that the Reindeer backends can work on. For example, an application would still need to use GLX or equivalent to be able to use the OpenGL backend. The Reindeer project also provides a package called GTK-Reindeer that makes this easier for developers of GTK+ applications.
Mathnetics is an API for creating advanced, interactive, Web-based mathematical applications. It defines various important mathematical objects that are inter-related and on which many numerical calculations can be done. It also features rendering of 3D objects onto an SVG canvas (to do so, it includes certain utilities such as browser sniffing, DOM node selection, and DOM readiness detection), which is quite robust. A few basic 3D objects are given (Line, Sphere, Cube), but the user can define any 3D object desired as per the specification.
QuartzCrystal is an application for rendering Quartz compositions to QuickTime movies and image sequences. It supports third party plugins (using both the official and unofficial API), as well as unsafe patches. It also supports spatial supersampling (antialiasing) and temporal supersampling (motion blur).
Fountain 3D is a little J2ME toy and a technology demo for a custom-made 3D wireframe engine with some benchmarking abilities thrown in. The camera is fully controllable by the user together with the simple particle simulation. The software doesn't require hardware acceleration; all J2ME compliant mobiles are supported.
