Method Details

[hide private]

init(self, generators=`[`Disk(aspect_ratio=0.5, bounds=BoundingBox(radius=0.5), mask=N`...`, **params)
(Constructor)

source code

Initialize this ParameterizedObject.

The values of parameters can be supplied as keyword arguments to the constructor (using parametername=parametervalue); these values will override the class default values for this one instance.

If no 'name' parameter is supplied, self.name defaults to the object's class name with a unique number appended to it.

Overrides: base.parameterizedobject.ParameterizedObject.__init__: (inherited documentation)

function(self, params)

source code

Selects and returns one of the patterns in the list.

Overrides: base.patterngenerator.PatternGenerator.function

Class Variable Details

generators

List of patterns from which to select.

Value:

ListParameter(default= [Constant()], precedence= 0.97, class_= PatternGenerator, b
ounds= (1, None), doc= "List of patterns from which to select.")

size

Scaling factor applied to all sub-patterns.

Value:

Number(default= 1.0, doc= "Scaling factor applied to all sub-patterns.")

index

Index into the list of pattern generators, on a scale from 0 (start of the list) to 1.0 (end of the list). Typically a random value or other number generator, to allow a different item to be selected each time.

Value:

Number(default= UniformRandom(lbound= 0, ubound= 1.0, seed= 76), bounds= (-1.0, 1.
0), precedence= 0.20, doc= """
        Index into the list of pattern generators, on a scale from 0
