12.10: Display Panel normal vector
The downward-speed generated by vortex induction acts in right-angle to the
surface. For every panel the program calculates a normal vector. This vector
stands in right-angle on the panel surface. For lift computation with
Vortex-Lattice-Method and for rendering the 3D-graphic this normal vector is of
vital importance.
Some times it is helpful for interpreting computation results to know the
direction of normal vectors.
The marked button is in charge to make the normal vectors visible / invisible.
The pictures below show the normal vectors and their direction on the panels.
