Calliper (Feret diameter) of a grain in measurement units, the projection length normal to it and its direction/trend.
Syntax
c = caliper(grains,dir)
cV = caliper(grains,'shortest')
cV = caliper(grains,'longest')Input
| grains | grain2d |
| dir | vector3d |
Output
| c | caliper at direction |dir| |
| cV | vector3d, norm(cV) is the length |
Options
| shortest | shortest caliper |
| longest | longest caliper = diameter of the grain |
