We compared 2D-DIC and 3D-DIC data for the same inflation experiment.
- class="label">•
The variation in displacements were larger for 3D-DIC than 2D-DIC.
- class="label">•
The variation in meridional strain was similar for both methods.
- class="label">•
The difference between 3D-DIC and 2D-DIC data were within the 3D-DIC variability.

2D-DIC could be an alternative to 3D-DIC for the specific case of an inflation test.
