Figure 19.10.2.2

A representation of the Euler GUI tool. The three-dimensional reconstruction is shown (lower left), along with a projection and class average for a particular orientation identified in the asymmetric triangle on the right. Each cylinder in the asymmetric triangle represents a projection direction, with its height representing the number of particles found in that orientation.
