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.

Density

· Latest version 0.00.11

· Density Model

1. Blocks are draggable in x-z plane

2. Added scales

3. Fluid height (nonlinear equation)

4. Solve for interaction forces as matrix system

5. Blocks are stackable

6. Lots left to do, see design doc

· Piccolo rendering

· JMonkeyEngine rendering

1. Integration with Piccolo/Java2D

2. Picking, block mass readouts

3. Embedded swing components doesn't handle focus/key events on Mac

4. We should look into Jogl/Xith to check better swing integration; some clues on the web indicate that Jogl/Xith works better in Java 1.6--if so, is this something we should pursue?

Radioactive Dating Game

· Collaborate with John on graphics, coordinate frames and transforms

Misc

· Resource deployment: discuss with Jonathan

Upcoming Work

· 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

· Discuss 1/r^2 sim with Wendy

· Discuss physics/math sim with Wendy

· Remove buffering from PSwing for rendering improvements, speed improvements and to avoid mac rendering problems

· Ramp Simulation, fixes and updates, including charts

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