Reads the LFM model data in form of HDF and text files, extracts MHD scalars and vectors, projects a chosen scalar onto a cut plane, and renders in 3D three possible stream lines of a chosen vector. The Main Control Panel allows to one choose the MHD scalar and vector, and the location of the cut plane. The Pick mode allows the mouse to pick an arbitrary set of starting points for field line traces in three different colors.

The {StreamLines} pageillustrates how field lines are computed from the MHD vector. The central element is the FieldLineTracer macro which takes the vector as its second input. The Pick module - here named Red, White, or Yellow Field Lines - allows the user to click a point in the image through which the field lines shall be drawn, and it feeds the relevant information into FieldLineTracer. This key macro is described in detail in the web reference.
