Figure 2
Snapshots of the samples corresponding to the (a), (b) 2D and (c), (d) 3D cases (see Section 2.2). Particle orientations are uniformly distributed (a), (b) over the rotation group SO(2) about the z axis (which is parallel to the incident X-ray beam direction) and (c), (d) over the rotation group SO(3). Here (a) and (c) are the bulk 3D samples, while (b) and (d) are the planar 2D samples. |
