Features

• generates scenes by running commands a given total number of times.

• fine control over the probability distribution for each command.

• scene generations are reproducible using a fixed seed.

• extensible with custom commands.

• allows for fuzz testing.

• fast (using Maya’s API, not the command layer).

Usage

>>> import revl
>>> commands = [
...     (4.0, revl.createTransform,),
...     (1.0, revl.createPrimitive, (), {'parent': True}),
... ]
>>> count = 100
>>> revl.run(commands, count, seed=1.23)

In this example, Revl invokes a total of 100 evaluations inequally shared between the two distinct commands provided, leading to create approximatively 80% of transforms, and 20% of primitives (plus their associated transforms). Also, the primitive type is picked randomly, and each primitive’s transform is randomly parented under another transform from the scene, possibly creating a scene with a deep DAG hierarchy.

See the Tutorial section from the documentation for more detailed examples and explanations on how to use Revl.
