In RhinoCommon there is a nice function to calculate the fov for a perspective view (GetCameraAngle()). It is possible to use this function to determine the fov for a parallel view? As you zoom in/out of a parallel view, the GetCameraAngle fov changes, but not as the perspective window does - looks like I need to adjust it by another factor.
EDIT: The is a description of doing this (with Rhino4?) here…http://news2.mcneel.com/scripts/dnewsweb.exe?cmd=article&group=rhino.plug-ins&item=39453&utag= however there appears to be no ViewRadius method in RhinoCommon.
Thanks in advance.
