Python and Java API / Rotating a georeferenced model
« on: March 17, 2017, 04:37:42 PM »
Hey all,
I'm trying to rotate a georeferenced model so that it is in a specific orientation when exported. When I do even simple rotations (like 90 degrees about Z axis, for example) I end up with a bizarre rotation. As a sanity check, I have used the same exact script to rotate a non-georeferenced model, and I had no problem doing exactly what I want.
Is there a secondary matrix for georeferenced models that I also need to refer to when trying to do this rotation? Like one that changes from local coordinates to absolute coordinate?
Example for yaw 90 degrees:
...
T = PhotoScan.Matrix( [[0,-1,0,0],
[1,0,0,0],
[0,0,1,0],
[0,0,0,1]]);
chunk.transform.matrix = chunk.transform.matrix * T
...
Many thanks,
Greg
