QW-3D software can calculate full 3D radiation patterns, with varying both phi and theta angles. In earlier software versions, these results could be visualised by export to HOOPS 3D Part Viewer for ACIS(c). Starting with version 6.0, an internal OpenGL window has been implemented for this purpose. Besides a variety of display options, it allows scale control and switching between linear and logarithmic scales, see e.g. Section UG 2.3.4.
