PhET Progress Report
July 5, 2007
An online version of this report is available here.
Here�s a pie chart representation of the time distribution.
Rotation
� Posted 2 new revisions, click here for latest version
� Added a second character
� Improvements from motion subproject
o Improved handling for time series
o Corrected physics for offset derivatives
o Improved playback/record panel
� Added multiple timeseries for acceleration, velocity (x, y + magnitude)
�
Remaining
work:
o
Exact
solution for circular motion
o
Minor UI
fixes
o
Minor
bugfixes
o
Handling
multiple objects on a single graph
o
Handling
multiple series on a single graph
o
Side
view/projections?
o
Spin the
wheel and release?� (or just in torque sim?)
Launchable JAR files
� Wrote utilities for automatically constructing launchable JAR files for all flavors of a simulation
� Simulations that have multiple flavors prompt the user with a pop-up dialog
� Fully functional, but needs some cleanup & reorganization
Energy Skate Park
� Posted 9 revisions, latest version is 2.02.11
� Improved support for reset
� Moved grid lines y=0 to the ground
� Fix in the physics that caused the skater to gain a boost of energy or fly away
�
There are
a few known deficiencies in the dynamics system, but they rarely cause
problems, so we have avoided this work.
�
How did
Mindy�s interviews go?
Installer
� Discussion of per-sim installers for offline use
� Feasibility test with launch4j (produces windows executables only)
� Let�s decide on a simulation-for-offline-use type for AAPT
License
� Discussion of compatible-licensed image media
�
Many clip
art collections are for personal use only
�
Should we
hire a graphic artist?
�
Should we
search for compatible-licensed image/clip art collections?
Build File
�
Performance improvements
�
Fixed a URL error
Upcoming Work
� Rotation/Torque for AAPT(see above)
� Simulations for offline-use
� build/deploy/test all simulations for the main site?
o Fixed �won�t run under 1.6 failure� for SDPM
o Many sims have improvements
o Many sims have fixed a known bug (swing thread)
� Licensing issues/Meet with Kate Tallman
� GUI for translation system
� CCK ��
o remove old CCK, upgrade to CCK DC Only version after some small fixes
