RenderPark is a test-bed system for physically based photo-realistic image synthesis. It's a free software package providing a solid implementation of a wide variety of state-of-the-art ray-tracing and radiosity algorithms. Although RenderPark is in the first place a tool for research and teaching, it is evolving towards a full featured physics based global illumination rendering system that also illumination engineers, architects, designers and artists will appreciate. Features: * reads models in MGF and new XRML (extended VRML'97) file format. * images can be saved in PPM, TIFF and Radiance PIC format, for which numerous convertors exist. * supports high dynamic range TIFF and PIC image output, suitable for lighting analysis purposes, e.g. using Radiance tools, or experimentation with tone mapping techniques ... * illuminated models after radiosity can be saved in VRML'97 format. * X-Windows/Motif based user interface. * interactive navigation using graphics hardware (OpenGL) with various optimizations that make it suited for large models. * wide range of tone mapping operators + calibrated monitor support. * batch rendering with control through command line arguments or Inter Process Communication. * rendering into an external canvas window makes RenderPark behave as a "plug-in" in other applications. Rendering algorithms implemented: Object-space radiance algorithms: * Galerkin radiosity (both gathering and shooting) with (or without) hierarchical refinement, higher order approximations, clustering, view-importance, ... * Stochastic Jacobi radiosity, also hierarchical with clustering, higher order approximations and view-importance as described in Philippe Bekaert's PhD thesis (recommended radiosity method) * Various random walk radiosity algorithms * Photon Mapping Pixel-driven radiance algorithms: * stochastic ray tracing (usable as a second pass after an object-space radiance algorithm, with special support for the photon map) * bi-directional path tracing. Using regular expressions, you can tune exactly what part of the light transport shall be computed.
State Changed From-To: open->closed I'll handle this. Committed, thank you! http://www.freebsd.org/cgi/query-pr.cgi?pr=41105
