Hello,
I have transformation matrices generated via alignment of rigid bodies in the loop. These matrices consist of rotation and translation. The alignment was done using ICP algorithm ''PointtoPoint'. Bodies which were aligned were not identical in vertices and faces / point clouds. When I apply generated transformation matrices to two rigid bodies and visualise results in the loop, I see the movement which mimic my needs.
For FEA I use open source software, Febio. When I do apply same transformation matrices, displacement and rotation, to rigid bodies, they do not show positive trend in movement. My system unit is mm. In displacement vector there are values of 50 and 70 mm.
What can be wrong?
Cheers,
Nataliya
