getStrains: Return strains edges are under in spherical retina
Description
This function returns information about how edges on the sphere
have been deformed from their flat state.Value
- A list containing two data frames
flat and spherical.
Each data frame contains for each edge in the flat or spherical meshes: LLength of the edge in the flat outlinelLength of the corresponding edge on the spherestrainThe strain of each connectionlogstrainThe logarithmic strain of each connection
