User files

• ~/.B.blend A blender file that is loaded at startup or whenever 'clear all' (CTRL-x) is executed. The user can define his presets (default materials / objects / etc.) in this file. This blender file differs in no way from other blender files. The current scene can be written to ~/.B.blend by executing 'save user defaults' (CTRL-U).
• ~/.Bfont The default postscript font which is loaded at startup. This font is used to define 3D-objects, not for drawing text in the user interface.
• ~/.Bfs An ASCII file with a list of directories. These directories are added as shortcuts to the file selector.
• ~/.Blog Contains the file name of the last written blender file. This name (and path) is used as initial preset when opening a blender file until the user specifies a new filename by opening or writing a blender file.
• Sources. server:/home/export/blender/OpenGL/src

• B.blend.c Definition of the default blender file (~/.B.blend) in char datatoc_B_blend[]
• Bfont.c Definition of the default postscript font (~/.Bfont) in char datatoc_Bfont[]
• Bfs.c Definition of two default shortcut directories: / and /tmp in char datatoc_Bfs[].
• Button.c This file contains functions to define and handle buttons. The most important function to define buttons is DefBut. A button is usually coupled to a memory location where the variable that the button changes is stored. At definition time variables include the lower and upper limits, the type of variable (bit / byte / float) and the type of button (slider / toggle / radio). The buttons are handled by the function DoButtons. This function checks all buttons for pending events. Whenever a button was activated this function returns the index number of the button.
• anim.c Unknown. Curves and stuff.
• arithb.c Defines functions for matrix, quaternion and vector calculations as well as calculations for distance between point and surface etc.
• arithbn.c Much like arithb.c.

• font.c Converts temporary font format generated in psfont.c to blender font format. Generates bezier curves from ASCII text and font definition.
• genfile.c A blender file consists of a memory dump of the structures used by blender. The blender file also contains the definition of the structures as they where in use by the blender that generated the blender file. The definition of these structures can be different in different blender releases. Blender is backward (and forward) compatible with other blender versions. When reading a blender file structures are converted to the current blender format. To do this blender saves the definition of the structures in something that is called the DNA in each blender file. The functions in genfile.c convert the blender include files to this DNA.
