FlyFly 3.1 contains three new stimuli:
Starfield 2 is the stimulus to create a general 3-dimensional "cloud" of dots that can move together via translation, or rotation around one of the XYZ axes. (See an earlier post from me for a video of
Starfield 2). The older cylindrical starfield is still available as "Starfield 1".
Target3D creates a circular target that can move along a 3-dimensional trajectory. It is the 3-D version of "Rect Target". We are using it in conjunction with Starfield 2 to create a target moving against background clutter, in order to study the effects of a moving background on target-detecting neurons in the fly.
ImageTarget is the "image" version of "Rect Target". It allows you to move a specified image along a 2-dimensional trajectory. We propose to use this stimulus to find out more about the kinds of visual features that target-tracking neurons are sensitive to.
