source: nanovis/branches/1.1/ContourLineFilter.h @ 4804

Last change on this file since 4804 was 3492, checked in by ldelgass, 7 years ago

Fix camera reset for nanovis. Includes refactoring of vector/matrix classes
in nanovis to consolidate into vrmath library. Also add preliminary canonical
view control to clients for testing.
