ElementArrayStim
¶
- class psychopy.visual.ElementArrayStim(*args, **kwargs)[source]¶
This stimulus class defines a field of elements whose behaviour can be independently controlled. Suitable for creating ‘global form’ stimuli or more detailed random dot stimuli. This is a lazy-imported class, therefore import using full path from psychopy.visual.elementarray import ElementArrayStim when inheriting from it.
This stimulus can draw thousands of elements without dropping a frame, but in order to achieve this performance, uses several OpenGL extensions only available on modern graphics cards (supporting OpenGL2.0). See the ElementArray demo.
- Parameters:
- win :
a
Window
object (required)- unitsNone, ‘height’, ‘norm’, ‘cm’, ‘deg’ or ‘pix’
If None then the current units of the
Window
will be used. See Units for the window and stimuli for explanation of other options.- nElements :
number of elements in the array.
