Incorrect Rotation Axis about webct HOT 4 CLOSED

Reproducable with config;

Config-WebCT.json

Looks like the rotation is on the model axis, and not the worldspace; hence why this has not been encountered before.

from webct.

Current approach is using gvxr.rotateScene() to rotate all meshes during capture setup.

And projections are generated by rotating "root";

Probably a likely assumption that rotateScene causes root to rotate, resulting in the projections' rotation to be incorrect compared to the fixed detector and source

from webct.

One fix is to rotate each sample mesh, however:

• Requires keeping track of all mesh nodes
• What happens when meshes are added / removed before and after a translation
  • e.g, rotate meshes, mesh deleted, reset rotation breaks due to missing node...
  • rotate meshes, add mesh, un-rotate meshes, but new mesh is now in an incorrect position

Is there a better way to rotate all scene nodes, and rotate the scene separately? Will have to find out

from webct.

Use computeCTAcquisition with None for path
https://sourceforge.net/p/gvirtualxray/gitroot/ci/master/tree/SimpleGVXR/include/acquisition.h#l258

And then getLastProjectionSet to get projections
