Planarizes surface hulls.
Hull Planarize
-
-
– Affects a single CV row.
If this option is selected, holding down the key lets you select hull lines on several different surfaces and flatten them all onto the same plane.
– Affects all CV rows in U direction (except possibly the first and last).
– Affects all CV rows in V direction (except possibly the first and last).
– Affects all CV rows in both U and V directions (except possibly the first and last).
For the last three settings, the first and last rows of CVs are only planarized if is turned on.
-
-
– The plane is calculated from the view vector (perpendicular to the active window) and the vector joining the end CVs of
the row.
– The plane is chosen as the one that best fits the set of CVs (similar to a least-square fitting) while going through both
end CVs.
-
-
This option appears only when is set to . It controls the number of times the position of the CVs is recalculated in both the U and V direction.
Note
Because the positions of the CVs already planarized in U are affected when planarizing in V, increasing the number of iterations
normally makes those positions converge toward some optimal values.
-
-
If this option is checked, the first and last row of CVs (in U and/or V) are also planarized. The corresponding surface edges
appear as straight lines on the planes of projection.
This option is available when is not set to .
-
-
This option determines the direction of projection for each CV.
– The direction of projection is along the hull line that is closest to the perpendicular of the plane.
– The direction of projection is perpendicular to the plane.
– The direction of projection is along the hull line toward the closest surface boundary.
-
-
If this option is checked, a deviation measurement showing the maximum deviation between the old and new surface appears.

-
If this option is checked, a green proxy of the original hull appears after the planarization operation.
