The Graphical User Interface (GUI) is mainly responsible for the development of a graphical work environment aiming to provide operator with an user-friendly interface to the SMART-PIV system.

The GUI will display all commands and graphic views (menu, buttons, on line help, 2D/3D visualisation, ...) in a double operative mode: the first will be used by non-expertise operators (user-friendly visualization of major experimental and numerical results); the second by trained operators being able to use commercial flow visualization SW.

The GUI will be based on innovative algorithms developed for data presentation in a user-friendly graphical way, thus providing a significant improvement in the system performance for a diffuse future use of PIV systems, which are today restricted to researchers or professionally trained operators only.

The GUI Software will present the operator with a suitable selection of information relevant for the flow field in an interactive fashion, by means of simple mouse operations. The output display will regard the following aspects:

2D/3D-volume display of vector field (from both Image Processing SW and Numerical Analysis SW);

2D/3D-streamlines and strikelines;

colouring of vectors according to some scalar field;

2D/3D-volume display of scalar fields, cut-out/scan through volume possible;

detailed comparison of experimental results with CFD output by means of simultaneous display of scalar fields/images and vectors;

all displays including scales, grids and annotations;

real-time visualisation of correlation peak;

display of series of images (real-time view of the camera output) and vector fields;

movies of all displays through time, storage of movies as AVI-files.
