1.       SHOW UNDEFORM SHAPE

This function enables the user to toggle on/off the un-deformed geometry of the model. The deformed parts are plotted in its original color while the un-deformed model is plotted in white.

2.       SCALE FACTOR

This function is used to adjust the default scale factor of the deformed part. The default is 1. It scales the plotted components to a user-defined proportion and displays them on screen. For example, if the user plots the deformed result, he/she could magnify the deformation by a factor of ten to see small deformation not readily visible during animation.
