Class: Interaction

bu.interaction. Interaction

An interaction to control a viewer. Each interaction captures one or several input device events, as keyboard keystrokes, or mouse movements, or touch gestures, and translates them into parameter values. There are two types of parameter values: static ones, that are captured and do not change along the time, and dynamics, that are values with a velocity and friction, that change along time from initial value to zero. Once captured this values interactions then trigger events sending them out.
