define cubic region for bounding box

[Twister]

Hi everybody,

I want to replace the existing region of a referenced chunk by a new cubic region, centered to [0,0,0] and aligned to the local coordinates of chunk, with a cube side length side_length. What would be the easiest way to do this? Thank you in advance.

Best regards

Twister

Hello Twister,

The following code should work for the chunk referenced in Local Coordinates:

Code: [Select]

import PhotoScan

side_length = 5.0 #set value here
chunk = PhotoScan.app.document.chunk
T = chunk.transform.matrix
chunk.region.center = T.inv().mulp(PhotoScan.Vector([0, 0, 0]))
chunk.region.size = PhotoScan.Vector([side_length, side_length, side_length]) / chunk.transform.matrix.scale()
chunk.region.rot = T.rotation().t()
print("script finished.")

Thank you, Alexey, it works fine!
