Figure 8
The 14 crystal projections used to measure accurate interfacial angles. These pictures are projections through the three-dimensional stack of slices (between 15 and 50 slices in each case) after rotation of the voxel array. The rotation angles were computed from the orientation matrix and then visually optimized to maximize the contrast of the crystal sections, which corresponds to perfect alignment of the prism zone axis parallel to the view direction. The process is similar to setting the crystal `in focus', as can be seen by comparing the aligned crystals with other crystals included in the field of view but not oriented. The morphology of the aligned sections (orange lines) was defined and used to compute the interfacial angles.
