| ===== Computational domain ===== | ===== Computational domain ===== | ||
| + | The calculation is performed on a rectangular domain that is divided into | ||
| + | rectangular voxels. Through these voxels the rays are passing, leaving some intensity | ||
| + | information there to be accumulated, summed with the other rays or being somehow interpreted. | ||
| + | The first information that needs to be given is the voxel size. This can be in principle | ||
| + | different in different directions, which can be useful especially to treat the different sample scale | ||
| + | in lateral directions (xy) and z direction. Even if most of the algorithms are not related to any | ||
| + | particular sample orientation, some sources are, so we recommend to have the sample oriented with surface | ||
| + | normal pointing the z direction. | ||
| + | |||
| + | The following input file example sets the x,y and z voxel size to 1 nm (note that all the quantities are always in base SI units). | ||
