### Euler Viewer

This Viewer shows the the frequency of the angles in the stack of images. Each point on the sphere stand for one angle pair.

## Usage

After loading a stack of images with header values for their angles the Euler Viewer shows cylinders representing the number of images with equivalent angles. The position of the cylinder belongs to a certain Euler angle pair. After clicking on one of the cylinders it is marked blue and the number of images as well as the Euler angle are displayed in the lower left window area. The radius of the sphere can be adjusted in the Controls window.
