A closer look

•Howto get the data about a project?

–Evolizer (Eclipse plug-in) from s.e.a.l. group

–Creates FAMIX model and stores it in mySQL DB

A closer look

•How to visualize the data

(in 3D)?

–JMonkeyEngine

–High perform

ance scene graph based graphicsAPI

–Open source, comes with many examples

A closer look

•How to get the m

etrics?

–MetricStore

interface returns dummy values

–Hopefully the realMetricStore

will be readysoon...
