====== Animation Frame File ======

The animation Frame file contains all of the data to be displayed on the model for a single frame of the animation.

===== Format =====

The Format of the file is a one line header containing 2 numbers. The rest of the file is a table with each line representing a different node. The meaning of the numbers in the header has changed between [[sassi:acs-sassi_user_interface| SASSI User Interface]] and [[sassi:PREP]].

The first number of each line in the data table is the node number for the animation data. The rest of the number on that line are the data for that node. The data in the table and the number of lines differs for each type of animation but the format frames should be consistent for all types of animation.  

==== Current ====

The current file header for [[sassi:acs-sassi_user_interface| SASSI User Interface]] has 2 integer numbers. The first number repents the number of data lines in the table while the second number represents the number of data columns in the frame file.  

==== Previous ====

The frame file for [[sassi:PREP]] contains an integer and a decimal number. The first number repents the number of data lines in the table while the second number is a scale factor for the data. The scale factor in the header was for an intermediate version of [[sassi:PREP]] that was never released. This number is not used by any animation type in any released version of Prep.

==== Comaptibility ====

Due to the frame format changes the frames generated by the modules in [[sassi:PREP]] cannot be used by the [[sassi:acs-sassi_user_interface| SASSI User Interface]], but since the scale factor does not affect the frame processing in [[sassi:PREP]] all of the frames generated by the User Interface can be used in PREP.
