What are visual effects?

Visual effects involve the integration of live-action footage and generated imagery to create environments which look realistic, but would be dangerous, expensive, impractical, or simply impossible to capture on film.

Amanda - building the platform


Services

class MakeMovieService(object):!!

@public! def greet_director(self, director_name):! return "hello %s" % (director_name,)!


We have a service, but lets make it do something useful

Amanda - building the platformInfrastructuresclass MakeMovieService(object):! storage = Dependency(“storage")! def _check_data_on_disk(self, files):! """ Check data is available! """! return self.storage.check_exists(files)!

Amanda - building the platformInfrastructuresclass MakeMovieService(object):! storage = Dependency(“storage")! def _check_data_on_disk(self, files):! """ Check data is available! """! return self.storage.check_exists(files)! def _get_shot(self, shot):! """ Get shot data! """! query = "<insert db query>"! return self._db.execute(query, (shot,))!!

Amanda - building the platformInfrastructuresclass MakeMovieService(object):! storage = Dependency(“storage")! def _check_data_on_disk(self, files):! """ Check data is available! """! return self.storage.check_exists(files)! def _get_shot(self, shot):! """ Get shot data! """! query = "<insert db query>"! return self._db.execute(query, (shot,))!! @public! def make_movie_magic(self, shotInfo):! """ Do some magic! """! shot = self._get_shot(shotInfo)! if not self._check_data_on_disk(shot["files"]):! self._log.error(‘files not found')! raise DataNotAvailable()! self._do_magic(shot["files"], self._config.production.jobsite())


Ok now it is doing something but that is one user, one service and not very useful at scale…


Service providers

services = ServiceProvider(! make_movies=MakeMovieService,! storage=StorageService! config=ConfigService! logging=LoggingService! __infrastructure__={! "_db": DbInfrastructure,! "_config": ConfigInfrastructure,! "_xmesh": XmeshInfrastructure,! "_log": LoggingInfrastructure! }!)!services.make_movies.make_movie_magic("shot1")!services.logging.change_logging_level("make_movies", "debug")!


Proxies

class Proxy(object):!!

def __getattr__(self, method):! def method_stand_in(*args, **kwargs):! return self._transport.publish(self._service, method, *args, **kwargs)! return method_stand_in!!

services = ServiceProvider(! make_movies=Proxy("make_movies", transport)!)!services.make_movies.do_movie_magic(“shot1”)!!


Ok, at this point we can scale a bit but what about concurrency/parallel processing?


This gives us all the building blocks to assemble a distributed system with the possibility to use the

best technologies for the given tasks
