Media Maker plugin

Description

The Media Maker plugin provides media generation API for Blue Brain BioExplorer.

API

Snapshot

The following example illustrates how to connect to the Blue Brain BioExplorer and export a snapshot of the current view to disk. The snapshot is exported to the /tmp folder, with a resolution of 512x512, and with 16 samples per pixel.

from bioexplorer import BioExplorer
from mediamaker import MovieMaker

bio_explorer = BioExplorer('localhost:5000')
movie_maker = MovieMaker(bio_explorer)

movie_maker.create_snapshot(
    path='/tmp/test.png',size=[512, 512], samples_per_pixel=16)

Movie

The following example illustrates how to connect to the Blue Brain BioExplorer and generate a set of frames according to some given camera control points. Frames are exported to the /tmp folder.

from bioexplorer import BioExplorer
from mediamaker import MovieMaker

bio_explorer = BioExplorer('localhost:5000')
movie_maker = MovieMaker(bio_explorer)

control_points = [
    {
        'apertureRadius': 0.0,
        'direction': [0.0, 0.0, -1.0],
        'focusDistance': 0.0,
        'origin': [0.5, 0.5, 1.5],
        'up': [0.0, 1.0, 0.0]
    },
    {
        'apertureRadius': 0.0,
        'direction': [-0.482, -0.351, -0.802],
        'focusDistance': 0.0,
        'origin': [2.020, 1.606, 3.030],
        'up': [-0.199, 0.936, -0.289]
    }
]

movie_maker.build_camera_path(
    control_points=control_points, nb_steps_between_control_points=50,
    smoothing_size=50)

movie_maker.set_current_frame(10)
movie_maker.create_movie(
    path='/tmp', size=[512, 512], samples_per_pixel=16, start_frame=10, end_frame=20)
