Math behind 'Zoom Extend'

[dale (Dale Fugier)]

Hi @flokart,

Here is come C++ code I posted a while back.

Zoom Extents to match trace image

Is there a way to ask an OpenNURBS view to zoom to extents to match the assigned ON_3dmViewTraceImage ? Similar to the code here: But purely using the OpenNURBS library? (eg. replicating what the RhinoDollyExtents call does in that example) and ideally a way to also account for the ON_3dmViewTraceImage assigned to the view?
