blender_scene_mvs

Adding a multiview system to a blender scene from a single script.

Using the script

This script assumes you already know a little bit about using the GUI in Blender. Open the python editor, copy and paste the file place_cameras_render.py.

At the top of the file you need to specify which object you want to center, it is called target_object_name, just add the name of the object you want to place cameras around. By default it will generate cameras in a north hemisphere around that object, you might need to play with radius. The cameras will be generated inside a collection called cameras.

I added 3 different camera patterns: random, structured, sweaping. See figure below.

#### variables to be set ####

target_object_name = 'cam_target'
radius_around_object = 0.6
nb_cameras = 200
radius = 1

dont_render = False

# choices: random, structured, sweaping 
sampling_method = 'structured'

bpy.context.scene.render.resolution_x = 1024  # width
bpy.context.scene.render.resolution_y = 1024  # height

camera_lens = 25

# output
filepath = os.path.join('E:\\', 'download', 'the_shed', 'the_shed', 'renders')
bpy.context.scene.render.image_settings.file_format = 'PNG'  # Example format

collection_name = "cameras"

Example

Here is an example of a multivew scene, the_shed. The original scene was downloaded here and see above for the 100 views that I rendered.
