2. Stitch Patch
|
"Stitch Patch" patchs
with polygon on the selected points.
a) Patch
"Stitch Patch" functions based on the the polyline
as well as "Stitch Center/Side".
It can patch with only quadrangle-polygon. (can't pacth with
triangle-polygon.)
Polygons are made between polylines like a ladder.
b) Patching 1 Polyline
You can patch on 1 polyline.This line must be formed by even-number
points.
If it is open-line, it is bridged in a half.
If it is close-line, it is bridged
in acutest angle part. (as well as "Stitch Center/Side")
c) Patching 2 Polyline
You can patch on 2 polyline. Number of points must be same in
both lines.
If both lines are open-line, near end-points in each lines are
bridged, and all other points are bridged in order.
If one is open-line and another
is close-line, end-point of lower number in open-line and point
near it in close-line are bridged, and all other points are bridged
in order.
If both are close-line, point of lowest number in all and point
near it are bridged, and all other points are bridged in order.
(as well as "Stitch Center/Side")
d) Patching in other case
In other case, as well as "Stitch Center/Side", it
functions with the following algorithm.
 |
|
no any case.
can't paitch |
|
delete polygons besieged
by points. |
|
re-analyze whether it's
possible. |
|
if possible, patch!! |
|
In this case, it asks by dialog.
Because polygon before execution is remade.
e) Polygon's UV and Normal
"Stitch Patch" has 2 settings
about patching polygon. These is on the "Stitch&Sew
Settings" dialog.
(It opens from plugin menu. )
|
 |
Enable "Inherit UVW".
If edit object has UVW-tag, patching polygons inherits UV value.
In standard tool("Bridge","Make Polygon"),
it is uninheritable.
Enable "Always Align To Normals". Patching polygon's
normals match other. But this functions on all polygons of edit
object. Therefore, when you edits object that has surface mixed,
disable this.
When disabled, in each execution it asks "Do reverse normals?"
in the dialog. You can select there.
