- HEADER (beginning of each file) * general header: + 8 char: "BPHYSICS" + 1 int: simulation type (same as PTCacheID->type) * custom header (same for sb, particles and cloth, but can be different for new dynamics) + 1 int: totpoint (number of points) + 1 int: data_types (bit flags for what the stored data is) - DATA (directly after header) *totpoint times the data as specified in data_types flags - simulation type soft body = 0, particles = 1, cloth = 2 - data types (more can be added easily when needed) data flag contains ---------------------------------------- index (1<<0) 1 int (index of current point) location (1<<1) 3 float velocity (1<<2) 3 float rotation (1<<3) 4 float (quaternion) avelocity (1<<4) 3 float (used for particles) xconst (1<<4) 3 float (used for cloth) size (1<<5) 1 float times (1<<6) 3 float (birth, die & lifetime of particle) boids (1<<7) 1 BoidData Notes: - Every frame is not nescessary since data is interpolated for the inbetween frames. - For now every point is needed for every cached frame, the "index" data type is reserved for future usage. - For loading external particle caches only "location" data is necessary, other needed values are determined from the given data. - Non-dynamic data should be written into an info file if external usage is desired. * Info file is named as normal cache files, but with frame number 0; * "Non-dynamic" means data such as particle times. * Written automatically when baking to disk so basically a library of particle simulations should be possible. - Old disk cache format is supported for reading, so pre 2.5 files shouldn't break. However old style memory cache (added during 2.5 development) is not supported. To keep memory cached simulations convert the cache to disk cache before svn update and save the blend. - External sb and cloth caches should be perfectly possible, but due to lack of testing these are not yet enabled in ui. Other changes: - Multiple point caches per dynamics system. * In the future these will hopefully be nla editable etc, but for now things are simple and the current (selected) point cache is used. * Changing the amount of cached points (for example particle count) is allowed, but might not give correct results if multiple caches are present. - Generalization of point cache baking etc operator & rna code. - Comb brushing particle hair didn't work smoothly. |

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/community/get-involved Community: http://www.blender.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/education-help Bug tracker: http://www.blender.org/development/report-a-bug Feature request tracker: http://wiki.blender.org/index.php/Requests
