PatternGenerator that moves another PatternGenerator over time.

To create a pattern at a new location, asks the underlying PatternGenerator to create a new pattern at a location translated by an amount based on the global time.

Method Details

[hide private]

init(self, **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)

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

source code

Construct new pattern out of the underlying one.

Overrides: base.patterngenerator.PatternGenerator.__call__

Class Variable Details

[hide private]

generator

Pattern to be translated.

Value:

ClassSelectorParameter(default= Constant(scale= 0.0), class_= PatternGenerator, do
c= """Pattern to be translated.""")

direction

The direction in which the pattern should move, in radians.

Value:

Number(default= 0, bounds= (-pi, pi), doc= """
        The direction in which the pattern should move, in radians.""")

speed

The speed with which the pattern should move, in sheet coordinates per simulation time unit.

Value:

Number(default= 1, bounds= (0.0, None), doc= """
        The speed with which the pattern should move,
        in sheet coordinates per simulation time unit.""")

reset_period

When pattern position should be reset, usually to the value of a dynamic parameter.

The pattern is reset whenever fmod(simulation_time,reset_time)==0.

Value:

Number(default= 1, bounds= (0.0, None), doc= """
        When pattern position should be reset, usually to the value of a dynamic p
arameter.

        The pattern is reset whenever fmod(simulation_time,reset_time)==0.""")

last_time

float(x) -> floating point number

Convert a string or number to a floating point number, if possible.

Value:

0.0
