Version 0.8.1, 21/05/02 ----------------------- -Reenable the Lobe_T_Min functionality which was accidentally disabled in version 0.8. Version 0.8, 20/12/01 --------------------- -Tried to fix NaN problems on Mac OS X. -All JPEG support can be removed with -DNOJPEG to allow compilation if libjpeg is not installed. -Output file format (JPEG or PPM) can now be selected by the extension of the filename specified. -Added option to log all vertexes to a text file for debugging -Various code tweaks to fix incompatibilities with Visual C++. BinSim will now compile and run on Windows! -Renamed .cc files to .cxx to be recognised by both Visual C++ and GCC. -Added a jet component -Added an optically thin disc component -Added a stellar wind component to allow hot stars in high mass X-ray binaries. Works identically to Corona components. -Added Disc_R_in parameter to allow discs with holes in the middle. Version 0.7.3, 11/10/01 ----------------------- -Added HighQuality_AA option to allow selective disabling of antialiasing option in high quality mode -Added Mac OS X options to the Makefile and a README.MacOSX file, courtesy of Paul Ray (Paul.Ray@nrl.navy.mil) -Simplified dependencies in Makefile removing many redundant entries. Version 0.7.2, 31/08/01 ----------------------- -Animations (to MPEGs) now work in off-screen mode. This was omitted from earlier versions (=forgotten!) Version 0.7.1, 30/07/01 ----------------------- -Fixed black spot on pole of companion star in v0.7 -Fixed phase_index bug in v0.7 which can lead to segmentation fault Version 0.7, 27/07/01 --------------------- -Miscellaneous bug fixes. -The documentation has been completely reorganised along standard lines. -PPM output has been reimplemented using Joerg Schmalzl's PPM code from the osdemo.c file in the Mesa distribution. At the moment this is only used in producing MPEGs and is not an option for stills. -Movies are now supported again, both in real time and as MPEG encoding. The companion star, stream, hot spot and disc all have animation. -Off screen rendering now supported, via the osbinsim binary. This includes the new 64bpp option in Mesa 3.5 if available. Version 0.6.1, 27/06/01 ----------------------- -Some documentation changes and corrections and several minor bug fixes. -Progress is now logged to the terminal. -Some parameters have sensible defaults so that the code will run without them, and more thorough value checking is performed of all parameters. -The output image filename can now be specified by the Image_File keyword. -SAMPLES parameter handling corrected. Allowed values are 2 (2x2 subsamples) or 4 (4x4). -Corona bug corrected. In 0.6, both coronae were accidentally controlled by Show_Corona1. -Images will now only be saved once the first time the binary is drawn, not at every redraw. -Should now build under GCC 3.0; version 0.6 will not. Version 0.6, 13/06/01 --------------------- Mainly this is an attempt to produce a test release based on a subset of features previously used. As such no major new features or components are present. A number of improvements have been made to the way some objects are rendered compared to previously released images. These include: -In high-quality mode background stars are now drawn as fuzzy circles. They now look round rather than squarish as they did before. The circle size also scales with brightness, so the apparent difference between bright and faint stars is more dramatic. -Granulation on the companion star and structure in the hotspot now varies on a scale of roughly fixed solid angle. Previously it varied on a fixed azimuth scale resulting in squashing towards the poles with structure appearing vertically streaked. -Stream now merges sensibly onto the companion star surface and the amount of the surface over which it blends can be controlled.
