May 28, 2009

An online version of this report is available here.

Here's a pie chart representation of the time distribution.

I'll be out of town and away from email June 8-23.

CCK

· Investigate techniques for circuit solution and companion models for storage elements

· Improve interface, algorithm, readability and testing for Modified Nodal Analysis in Scala

Radioactive Dating Game

· Work with John on meter node and model components

3D Engines

· Investigate Jogl and swing embedding and compatibility with Xith3d

· Read about performance and portability of GLJPanel

· Investigate 3dzzd engine, LGPL'ed 2 months ago

· Apparently JOGL uses a certificate that allows usage in web start with no permission request, see thread and test link

· Recommendation: Still need to spend some time setting up feasibility tests with Xith3D/Jogl, but they will have to have enticing features to overcome their many drawbacks (compared to lwjgl+jme)

Piccolo

· Bugfixes for PSwing, with Chris, see #1670

Upcoming Work

· Bugfixes for CCK physics

· Test resource deployment

· Continue model for density sim (object editor, movable scales, spherical objects, etc)

· Continue integrating JMonkeyEngine with PhET build process and phetcommon

· Investigate swing behavior in JOGL/Xith

· Investigate 3dzzd, including design and features (e.g. picking)

· Discuss 1/r^2 sim with Wendy

· Discuss physics/math sim with Wendy

· Remove buffering from PSwing

· Ramp Simulation, fixes and updates, including charts

· For details, See ticket report "Sam R: Report" here
