YafaRay is a raytracing engine. Raytracing is an image rendering technique for generating realistic images by tracing the path of light through a 3D scene. A render engine consists of a "faceless" computer program that interacts with a host 3D application to provide specific raytracing capabilities "on demand". Blender 3D is the host application of YafaRay.
Dandelion is a 3D graph rendering application which can be controlled across a network. Its main purpose is to allow clear network graphs to be rendered in a window, which can be controlled by a separate application or the user. The Dandelion visualization is actually controlled by issuing simple commands to it across the network (although this could all be happening on a single machine). The Dandelion source includes a set of very simple libraries which can be incorporated into other applications and which can be used to send these commands. Libraries are included for C, C#, Java, and Python. The project was developed at Liverpool John Moores University within the PROTECT Centre.
