An online version of this report is available here.

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

Motion Series

· Added 6 new changes, latest version is 1.03.42

o Fixed: Prevent the chart from drawing lines "back in time" when pressing record in the middle of a playback sequence

o Fixed: Chart text boxes should always show correct values, even after charts are full.

o Removed all references to "work" in the work/energy tab of The Ramp, including graphs and bar charts

o Removed the force graph from the work/energy tab of The Ramp

o Renamed the "work/energy" ramp tab to "Energy"

o Fixed the layout of the "Energy" tab to match the "Force Graphs" tab

Gravity Force Lab

· Minor fixes

· Posted on main site as 1.00

Misc

· Discussed preferred Font issue as part of #1765

· Feasibility tests for replacing motion/control-graph module

· Neuron sim, collaboration with John

· Density sim/3D/Piccolo, discussion with Jonathan & Chris

Upcoming Work

· Ramp simulation, see to-do list

· E&E graph should have record/playback, use Scala recording controls.

1. Noah provided a mock-up, see email

2. Rewrite this component in Java?

· Discuss MyCanvas layout implementation with Chris, John, Jonathan

1. Still experimenting with it

· Posted sim dependencies, and sims for common libraries and a report for ramp in particular

1. Decide which of these sims should be reposted, or whether we'd like to investigate the source code for changes before investing in repost + retest.

2. Chris recommended making common text change logs available to testers

· Motion Suite: need to discuss Robot Moving Company games with NP

· CCK - new Physics implementation, testing and performance analysis (with Sam M)

· JMonkeyEngine/Xith /3dzzd/Flash/Papervision3d/Feng Gui

· Make it possible to redeploy sims with common changes without retesting the sim when we redeploy again
