Simple 3D visualization (OpenCascade, Qt).

The application is designed to visualize the movement of several objects in 3D space. The motion path is described by the list of coordinates (dX, dY, dZ, velocity). The motion path should be imported from a file (some simple format - to be determined) The application should allow importing objects from STP or IGES format files. Objects from imported files should move according to the imported motion path. It should be possible to specify for each imported object: - coordinates (X, Y, Z) in which a given object is to be located at the moment of visualization start - a set of flags defining which axis movement will affect the movement of the given object some objects will only be able to move in one or two axes The application should consist of - main window here can import files, configure necessary parameters, bring up a window with visualization - windows with visualization it should be possible to rotate the scene, zoom in and out, start, stop, pause button to control the visualization Application should work in Windows7 and higher. Preferred is the use of Qt5 and OpenCascade libraries, but I am open to other ideas. PS. I have no idea what the cost may be, please do not look at the budget range.
