Added a new pooling allocator for Bmesh based upon the pool allocator availible in the Boost C++ library as described here: http://www.boost.org/doc/libs/1_34_0/libs/pool/doc/concepts.html Each pool allocates elements of a fixed size, so every element type in a mesh gets its own pool. For instance verts occupy a different pool than edges. Each pool is comprised of multiple arrays of a fixed size and allocating /freeing elements is simple as removing or adding a head to a linked list. Since the list of free elements is interleaved throughout the unused space in the arrays, the overhead for storing the free list is only 1 pointer total per pool. This makes building/destroying bmesh structures much faster and saves quite a bit of memory as well.
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
