Saving the viewing matrix

The current orientation on the screen is defined by the center of rotation and the rotation and translation (modelview) matrix. The following script saves this into a file given as an argument. In addition, the near and far clipping planes are saved.

Usage:

Save the current view:

@mmat.scr view1.scr

Restore the saved view:

@view1.scr

// expects a file as a parameter
echo scene set rtc=[scene get rtc] > $1
echo scene set near=[scene get near] >> $1
echo scene set far=[scene get far] >> $1
