This function allows to alternate two PIV images in a rapid sequence, in order to visualize the underlying flow motion.
Images can be any size: simple correlation-windows or full-scale images.
A velocity field can be shown on the images, so that the flow field resulting from the PIV analysis can be visually inspected comparing the particles motion.
Additional functions to zoom-in and pan allows a better analysis of the images.
The resulting animation can be exported as a GIF file.
