Radiator is a radiosity renderer. It implements matrix, progressive, and hierarchical radiosity with clustering, and handles a variety of model formats, including multiresolution models. It also comes with a visualisation front-end, 'radvis', useful for previewing scenes or teaching, a scene viewer 'slview', and a Mesa-based batch rendering program, 'slrender'.
Raja (RAy tracer in JAva) is a complete, object oriented ray tracer written in Java. It fully supports transparency, intersection, union, complement, mirroring, basic anti-aliasing, and exact acne correction. We aim to do a complete, easy to use and distributed renderer to do images or movies over a network of heterogeneous computers.
Raw Image Loader is a GIMP 1.1 plug-in which allows loading arbitrary bit-mapped data into the GIMP. It supports 24-bit RGB, Planar RGB, RGBA, and indexed data. Two types of indexed palettes are supported (standard RGB style and the BGRX palette used by Windows bitmaps). Latest versions also allow saving to raw RGB, Planar RGB, and indexed formats.
RenderDotC (RDC) is a photorealistic rendering toolkit which adheres to the RenderMan(R) standard. Using the Reyes architecture, RDC supports advanced capabilities such as motion blur, depth of field, trim curves, texture/environment/displacement mapping, and programmable shading in the RenderMan Shading Language. The shader compiler included in the toolkit compiles shaders all the way to machine language for the highest possible performance.
RenderPark is a photo-realistic rendering tool being developed at the Computer Graphics Research Group of the Katholieke Universiteit Leuven, in Belgium. The goal is to offer a solid implementation of many existing photo-realistic rendering algorithms in order to compare them on a fair basis, evaluate benefits and shortcomings, find solutions for the latter and to develop new algorithms that are more robust and efficient than the algorithms that are available today. RenderPark will offer you several state-of-the-art rendering algorithms that are not yet present in other rendering packages, not even in expensive ones. Allthough RenderPark is in the first place a test-bed for rendering algorithms, it is evolving towards a full-featured physics-based global illumination rendering system.
ResCafé is a Swing-based Java utility for reading and extracting resources such as ICONs and MENUs from the Resource Forks of Macintosh files. In particular, it allows Linux users to use nifty Mac-only icons with their favorite desktop, e.g., KDE. It is somewhat similar to ResEdit on MacOS except that it is not an editor; it operates on files in a read-only fashion. The various resource types are parsed by auto-detected plugin handler classes.
