#4742 exported normals are now correct #4821 & 4956 for complex movements in/outflows can now also use the animated mesh option - new features * isosurface subdivision: directly creates a finer surface mesh from the simulation data. this increases simulation time and harddisk usage, though, so be careful - usually values of 2-4 should be enough. * fluidsim particles: extended model for particle simulation and generation. When isosurface subdivision is enabled, the particles are now included in the surface generation, giving a better impression of a single connected surface. Note - the particles are only included in the final surface mesh, so the preview surface shows none of the particle effects. * particle loading: different types of particles can now be selected for display: drops, floats and tracers. This is a bit obsolete due to the extensions mentioned above, but might still be useful. Floats are just particles floating on the fluid surface, could be used for e.g. foam. * moving objects impact factor: this is another tweaking option, as the handling of moving objects is still not conserving mass. setting this to zero simply deletes the fluid, 1 is the default, while larger values cause a stronger impact. For tweaking the simulation: if fluid disappears, try increasing this value, and if too much is appearing reduce it. You can even use negative values for some strange results :) - more code cleanup, e.g. removed config file writing in fluidsim.c, added additional safety checks for particles & fluidsim domains (these currently dont work together). I also removed the "build particles" debug message in effects.c (seemed to be unnecessary?). Some more info on the new features: Here are two test animations showing the difference between using the particle generation with isosurface subdivision. This is how it would look with the old solver version: http://www10.informatik.uni-erlangen.de/~sinithue/blender/fluid6_fl6manc4_1noparts.mpg and this with the new one: http://www10.informatik.uni-erlangen.de/~sinithue/blender/fluid6_fl6manc4_2wparts.mpg Both simulations use a resolution of 64, however, the version with particles takes significantly longer (almost twice as long). The .blend file for a similar setup can be found here: http://www10.informatik.uni-erlangen.de/~sinithue/blender/fluid6_testmanc4.blend (Minor Tips for this file: dont enable subdivions of characters until rendering, thus leave off for simulation, as it uses the rendering settings! For making nice pictures switch on subdivion, and OSA.) And here's a picture of old vs. new (for webpage or so): http://www10.informatik.uni-erlangen.de/~sinithue/blender/fluid6_manc4compare.png |

Welcome to the fun world of open source. For instructions on building and installing Blender, please see the file named INSTALL. ---------------------.Blanguages and the .blender directory--------------------- The .blender directory holds various data files for Blender. In the 2.28a release those are the .Blanguages file containing a list of translations, the translations themselves and a default ttf font. Blender checks for the presence of this directory in several locations: - the current directory - your home directory - On OSX, the blender bundle is also checked - On Windows, the installation dir is checked. If you get a 'File ".Blanguages" not found' warning, try to copy the .blender dir to one of these locations (your home directory being recommended). -------------------------------------Links-------------------------------------- Getting Involved: http://www.blender.org/docs/get_involved.html Community: http://www.blender3d.org/Community/ Main blender development site: http://www.blender.org/ The Blender project homepage: http://projects.blender.org/projects/bf-blender/ Documentation: http://www.blender.org/modules.php?op=modload&name=documentation&file=index Bug tracker: http://projects.blender.org/tracker/?atid=125&group_id=9&func=browse Feature request tracker: http://projects.blender.org/tracker/?atid=128&group_id=9&func=browse
