Using remote computing facilities
effectively
If remote computing is available, it can speed
up the calculation of photogrammetric models
considerably. However, not all processes during
the creation of a 3D-model are equally suitable
for remote computing. It is recommended to
finish all CPU-heavy steps (alignment, dense
point cloud generation, polygon mesh
generation) on remote, while all interaction
heavy steps involving a lot of data loading
(masking, marker placement, point cloud and
mesh editing), and thus on a remote computer
a lot of data transfer, should be carried out on
a local computer.
Additionally, for all programs offering batch
processing, it is advisable to set up batch
operations that run autonomously, e.g.
overnight. Although sometimes steps have to
be repeated later, e.g. because the program
does not automatically set crop parameters
appropriately for dense point cloud calculations,
the avoidance of idle time is usually a
significant gain in overall work speed. If
available, a save-after-each-step option should
be used. It allows interrupting calculation of
large batches with minimal loss of completed
work.
