#34088: Gyoto (new port) -- General relativistic geodesic integration and ray- tracing --------------------------------------+------------------------------------- Reporter: thibaut.paumard@… | Owner: macports-tickets@… Type: submission | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.0.4 Keywords: | Port: Gyoto --------------------------------------+------------------------------------- Dear macports developers, Gyoto aims at providing a framework for computing orbits and ray-traced images in General relativity. It consists in a C++ shared library (libgyoto), utility programs (gyoto, gyotoy), and a plug-in for the Yorick programming language. Gyoto can be extended with plug-ins. To test the software: - run {{{gyotoy}}} (mind the final "y") from the command-line. A window will be displayed, representing the orbit of a star around a Kerr black- hole. - unpack the source and go to ${worksrcpath}/doc/examples. You can ray- trace the XML sceneries (except the two "rotstar" ones) with: {{{ for file in * ; do gyoto $file ${file%xml}fits; done }}} The result will be a bunch of FITS images which you can look at using a FITS viewer, for instance spydr from the yorick-spydr port: {{{ spydr *.fits }}} You will see the gravitationally-lensed image of a number of objects in the vicinity of a Kerr black-hole. I hope you will be able to accept this port. Best regards, Thibaut. -- Ticket URL: <https://trac.macports.org/ticket/34088> MacPorts <http://www.macports.org/> Ports system for Mac OS
