(behaviors via agentsagents)

BPC: Art and Computation – Summer 2007 20

Sounds and Images in DAFFIESounds and Images in DAFFIE

Images may be appliquéd to the surface of an object (flat or curved)

Sounds may be attached to objects (locations in 3D)

Images & objects may be sequenced to generate animation
