                                        RandomDotStereogram

Random dot stereogram using rectangular black and white patches.

Based on Matlab code originally from Jenny Read, implemented in Topographica by Tikesh Ramtohul (2006).

Method Details

[hide private]

call(self, **params_to_override)
(Call operator)

source code

Call the subclasses 'function' method on a rotated and scaled coordinate system.

Creates and fills an array with the requested pattern. If called without any params, uses the values for the Parameters as currently set on the object. Otherwise, any params specified override those currently set on the object.

Overrides: base.patterngenerator.PatternGenerator.__call__: (inherited documentation)
