Move origin

[chr00t]

Hello,

Would you complete that snippet on how to change the origin?

I want the first camera to become the new origin

import PhotoScan
import math
doc = PhotoScan.app.document
doc.open("project.psx")
chunk = doc.chunk
camera_becoming_origin = chunk.cameras[0];

then transform ?

Hello chr00t,

Code: [Select]

import PhotoScan

chunk = PhotoScan.app.document.chunk
origin = chunk.cameras[0].center #first camera center

T = PhotoScan.Matrix().diag([1,1,1,1])
for i in range(3):
T[i,3] = -origin[i]
chunk.transform.matrix = chunk.transform.matrix * T
But you might need to perform check whether the camera is aligned and camera index is not out of range, in case you are including the script in some large automated pipeline.

I'll consider checking names and range later on for sure

But why is this happening?

Sorry, there was a typo, origin  = chunk.cameras[0].center

Working as a charm,

Thanks Alexey
