psychopy.visual - many visual stimuli¶

Window to display all stimuli below.

Windows and and display devices:

• Window is the main class to display objects
• Warper for non-flat projection screens
• ProjectorFramePacker for handling displays with
• Rift for Oculus Rift support (Windows 64bit only)

Commonly used:

• ImageStim to show images
• TextStim to show text
• TextBox rewrite of TextStim (faster/better but only monospace fonts)

Shapes (all special classes of ShapeStim):

• ShapeStim to draw shapes with arbitrary numbers of vertices
• Rect to show rectangles
• Circle to show circles
• Polygon to show polygons
• Line to show a line

Images and patterns:

• ImageStim to show images
• SimpleImageStim to show images without bells and whistles
• GratingStim to show gratings
• RadialStim to show annulus, a rotating wedge, a checkerboard etc
• NoiseStim to show filtered noise patterns of various forms
• EnvelopeGrating to generate second-order stimuli (gratings that can have a carrier and envelope)

Multiple stimuli:

• ElementArrayStim to show many stimuli of the same type
• DotStim to show and control movement of dots

Other stimuli:

• MovieStim to show movies
• Slider a new improved class to collect ratings
• RatingScale to collect ratings
• CustomMouse to change the cursor in windows with GUI. OBS: will be deprecated soon

Meta stimuli (stimuli that operate on other stimuli):

• BufferImageStim to make a faster-to-show “screenshot” of other stimuli
• Aperture to restrict visibility area of other stimuli

Helper functions:

• psychopy.visual.filters for creating grating textures and Gaussian masks etc.
• Helper functions for tests about whether one stimulus contains another
• unittools to convert deg<->radians
• monitorunittools to convert cm<->pix<->deg etc.
• psychopy.tools.colorspacetools to convert between supported color spaces
