AFNI file: README.render_scripts

Format of AFNI Rendering Scripts ================================ This document assumes you are familiar with operation of the AFNI Volume Rendering plugin (plug_render.c). By examining the output of one of the "Scripts->Save" buttons, you can probably guess most of the format of a .rset file. Each rendering frame starts with the string "***RENDER", and then is followed by a list of variable assignments. Each variable assignment should be on a separate line, and the blanks around the "=" signs are mandatory. Please note well that you cannot use the Automate expression feature in a .rset file: the right hand side of each assignment must be a number, or a symbolic name (as for the cutout types, infra). You also cannot use the "Expr > 0" cutout type in a .rset file, since that requires a symbolic expression on the RHS of the assignment, and the .rset I/O routines aren't programmed to handle this special case. When a .rset file is written out, the first ***RENDER frame contains definitions of all the rendering state variables. Succeeding frames only define variables that change from the previous frame. Comments may be included using the C++ notation "//" (=comment to end of line). At the present time, the dataset name (_name) variables are not used by the renderer. Some other variables are only used if certain toggles on the "Scripts" menu are activated: * The sub-brick index variables (*_ival) are used only if the "Brick Index?" toggle is activated. * The brightness (bright_) variables and opacity (opacity_) variables are used only if the "Alter Grafs?" toggle is activated. * The dataset ID codes (_idc variables) are only used if the "Alter Dsets?" toggle is activated. The section below is a .rset file to which I have added comments in order to indicate the function of each variable.
