Camera Save and Load as CSV Files for Vue

Two python scripts for Vue for loading and saving camera information to and from CSV files (comma separated values). savecameradata.py saves camera position, focus and other data into a CSV file. loadcameradata.py loads a CSV file into Vue and applies it to the camera. The two scripts are useful for moving camera animations between scenes.

It also allows a stationary camera to be moved between scenes.

# - savecameradata.py
# - By Mark Caldwell
# - Version 0.3
# - 1st September 2009
# - Copyright Mark Caldwell 2006
# - Tested with Vue 7 Infinite 7.5
#
# How to use in 4 easy steps
#
# 1. Download this file onto your computer
#
# 2. Change Path to Saved File
#
# 3. Then run script and wait for it to work
#    To run it go to Python -> Run Python Script
#    Then locate the file on your computer
#
# 4. Camera path and rotation are now stored in the CSV
#    File and can be loaded using loadcameradata.csv
