Energy Skate Park
About 7 hours of work this
week.
Discussions with Erik Neumann
Collaboration with Dubson
- Tested
spline implementation
- Discussed
Lagrangian for offset center of mass computation
Implementation
- Added
2d mode to sandbox
- Added
editable splines
- Particle
is draggable
Look and Feel
- Discussed
with Wendy.
- Investigated
Liquid & Oyoaha implementations.
- Implemented
Liquid & Oyoaha for Energy Skate
Park:
- http://www.colorado.edu/physics/phet/dev/ec3/1.05.05/
- See:
“Look and Feel” menu
- We
should discuss possibility of Java 1.5 before resorting to another
skinnable l&f.
Repository Migration
- Collaborated
with John
- Postponed
due to a Sourceforge service outage.
- Sourceforge
said it should have been back by Feb 21, but today (Feb 22) status is
still listed as “Unscheduled Outage”
- Process is more or less automated
- We’ll
try again Feb 24
Piccolo
Bounded drag handler
Ruler
- Added
QWI ruler to shared graphics code repository (for use in optical tweezers)
Upcoming Work (in
order of proposed activity)
- Energy
Skate Park
a.
Collaborate with Dubson to improve physical model
b.
Evaluate new physical model before working on any
physics-related bugs.
c.
Track should bump up when beneath ground
- Collaborate
with De Goes/Malley to convert source code repository to Subversion
- Collaborate
with De Goes to improve simulation build process & isolate dependencies.
- Rotational
Motion Simulation I
a.
Time series/playback
b.
Lots of minor user interface updates
c.
Performance enhancement
- Rotational
Motion Simulation II
- CCK…
Issues
- Continue
spline physics reimplementation with Dubson?
- Discussion
of cost/benefit?
