- "current primary view direction" in TaskProjGroup is
read only, but can obtain focus. This can cause events
to be unexpectedly passed to other objects.
- use current 3D window direction as starting
direction for DrawViewPart and ProjectionGroup
- if a Face is selected, use Face normal as
starting direction.
DPG used a pair of large tables to determine view
direction and rotation vector when subject was rotated
and spun. There were many errors in the tables that
needed manual checking to correct. The new version
uses calculations on a virtual glass cube to find view
direction and rotation vector.
