- | This logic is needed as an intermediate step to get 3D model from 2D images. In order to reconstruct the full model we need to know the relationship between the images (projections) we have - how they are located in 3D relative to each other. | + | This logic is needed as an intermediate step to get from 2D images to a 3D volume.

In case any reference model for the particle is available, it can be used as 'anchor set' that would increase the precision of the output. | In case any reference model for the particle is available, it can be used as 'anchor set' that would increase the precision of the output. | ||
- | However, when no prior model is available for the particles of interest, determination of [[https://en.wikipedia.org/wiki/Euler_angles|Euler angles]] should be done de novo. This logic does it based on [[https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3334316|Common line theorem]]. | + | However, when no prior model is available for the particles of interest, determination of [[https://en.wikipedia.org/wiki/Euler_angles|Euler angles]] should be done de novo.
