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

Ladybug 2D

· Started framework for Ladybug 2D sim in Scala

o Model/View coordinates and transform & scaling

o User interaction

o History is recorded

o Velocity is estimated and shown

· Lots to do

Scala

· Added scala to build process, with help from Chris

· Added scala libraries & license annotations to SVN

· Discovered that Proguard properly handles scala code, scala library ends up increasing JAR size by 44kb; this will increase as Scala API is more heavily relied on

· Currently using scala for 1.4 JVM, if we are really moving to 1.5 we should move this forward as well

Meeting

· Collaborated with Chris & John prioritizing IOM tickets

Updating to Java 1.5

· Enabled warning message that runs in 1.4

· See test JARs here

· Need to add support to JNLP launcher (already supported in JAR Launcher)

Sim-Tracking

· Meetings & Discussions, verified some tickets

Misc

· Fix translation-deploy process so it can run outside of the IDE, need to set up Marj to use Ant to launch this

· Discussion of scene graph coordinates, with Chris

Upcoming Work
