Streaklines show the progress of a particle in a changing vector field. This is in contrast to streamlines, which follow the path of a particle in a static vector field. In this example, a probe point is used to set the starting points of the streaklines. To use this example, first go to Options in the Image window and choose "View Control". Then in the Mode menu, choose "Cursors". This will make the probe "grid_pts" active. A bounding box and a small square will appear which marks the probe point. The probe defines a point around which a regular grid will be constructed using the Grid module. The left mouse button can be used to click on, and move the probe point. You can put Execute on Change on so that as you change probe points, Data Explorer will re-execute the program. // comment: // comment: "series_data" is a receiver which receives a series field from a simple set of modules to the right of the first part of the visual program you see. Use the scroll bar at the bottom of the visual program editor to see this part. // comment: // comment: Now choose Open All Control Panels in the Windows menu. You will find an interactor which controls the ending frame for the streaklines. In this example, the value was saved as 2. This means that only frames 0, 1, and 2 will be used to construct the streaklines. Try increasing the interactor value to see how the streaklines progress in time. (There are a total of six frames in this simple example.) // workspace: width = 1447, height = 588 // layout: snap = 0, width = 50, height = 50, align = UL // macro main( ) -> ( ) { // // node Construct[1]: x = 781, y = 26, inputs = 4, label = Construct // input[3]: defaulting = 0, visible = 1, type = 8, value = [10] // input[4]: defaulting = 0, visible = 1, type = 16777245, value = {[1.0 0 0]} // main_Construct_1_out_1 = Construct( main_Construct_1_in_1, main_Construct_1_in_2, main_Construct_1_in_3, main_Construct_1_in_4 ) [instance: 1, cache: 1];
