nurbsCage.tsx |
| for tS ver 6 and up |
Create a
polgon cage to modify the control vertices of a nurbs patch. Edit
the cage with point edit tools to change the shape of the patch.
This also opens up the ability to use the snapping tools with
nurbs surfaces. Click once to activate and click again to
deactivate and break the link between the cage and the patch. |
|
 |
|
The picture shows a 1x1 plane. Normal trueSpace
nurbs edit doesn't give access to the internal control points.
The central control points can be edited using the nurbsCage
plugin. Do not add or subtract any geometry from the cage. Any geometry added will be ignored and any geometry subtracted will probably cause a crash. |
|
 |
invertCurve.tsx |
| for tS ver 6 and up |
Reverse the direction of a curve. Have nurbsinfo open to see the result. |
|
|
 |
invertPatch.tsx |
| for tS ver 6 and up |
Reverse the direction of a nurbs patch in the u or v direction or swap the u and v. Have nurbsinfo open to see the result. |
|
note: original version on Oct 1 2006 was the wrong version. the correct program was uploaded on Nov 24 2006 |

 |
weldPatch.tsx |
| for tS ver 6 and up |
Weldpatch
will take 2 patches that have been glued together and weld them
together to create a single patch. The u and v directions of the
patches must be in the same direction. The 2 patches must have
the same number of spans in u. |
|
 |
|
Nurbsinfo only
works with 1 patch at a time, but the composite picture above
illustrates the orientation needed for the patches to be welded and it
shows that they both have the same number of u spans. The patch on the left was selected before the glue tool was invoked. |
|
 |
|
Here is the result.
The first row of the second object is lost to the weld process.
Ideally there would be no gap between the 2 patches before the
weld is run. It's probably best to stitch the 2 patches
together, convert to a plain patch, and then use nurbsinfo with
invertPatch to make sure they are lined up properly. The original
glued patches are not deleted from the scene. |
|
 |
weldcurve.tsx |
| for tS ver 6 and up |
The
weldcurve
plugin will take 2 curves that have been glued together and weld them
together to create a single curve. The tail of the curve that
was
selected when the 2 curves where glued will connect to the head of the
second curve. |

|
Sept 30 2006 v1.1 minor changes to help text and removed unnecessary messagebox |
|
 |
nurbsinfo.tsx |
| for tS6 and up |
The
nurbsinfo
plugin will display information for nurbs patches and curves.
The
most useful information is the number of spans. Only the U
information is populated for curves. Click to turn it on.
Click again to turn it off. Does not work properly in modeller 4 view mode. |
|
|
|
The sphere "head/origin" is larger than the cone "tail/u direction". |
|
Sept 30 2006 v1.1 workaround for wheel mouse sticking, show head and tail of curve, show origin and u direction of nurbs patch |
|
 |
rebuildPatch.tsx |
| for tS6 and up |
The
rebuildpatch
plugin will reconstruct a patch with a given number of spans in the U
and V directions. The slider is limited to values between 1
and
16. Higher values can be typed into the text boxes.
The
current values are shown at the top of the dialog. For tS7
and up
the bridge may be turned off to prevent the new patch from shifting
position. |
|
 |
|
 |
|
 |
rebuildCurve.tsx |
| for tS ver 6 and up |
The
rebuildcurve
plugin will recreate a curve with a given number of equally spaced
spans. The dialog is the same as with rebuildPatch, but without the V. |
|
Below is a curve that was rebuilt from 24 spans
down to 12 spans. |

Sept 27 2006 still v1.0 but modified to update info panel |
