Polygon conversion
Polygon conversion
Convert polygon faces to triangles or quadrangles
Convert NURBS surfaces
to a polygon mesh
You
can convert a NURBS surface to a polygon mesh whether it was created in
Maya or imported into Maya from another 3D application. Trimmed
surfaces are also converted in the process.
If the NURBS surface
has a texture applied to it, this texture is assigned to the new
polygonal object. The NURBS to Polygons action bakes the NURBS UV values
onto the corresponding polygonal vertices.
To convert NURBS to polygons
- Select the NURBS surface and choose
Modify > Convert > NURBS to Polygons.
A polygonal representation of the surface is created at the same
position as the NURBS surface.
If you convert the NURBS
surface with construction history on, you can edit the NURBS surface
and the polygonal surface will be recreated to match.
Notes
- If a NURBS surface is converted into
a polygonal object using the NURBS To Polygons feature, and if the
history of the NURBS surface is modified to generate an invalid
(Null) NURBS surface, the following warning message displays:
Warning:
nurbsTesselate1 (Nurbs Tesselate Node): invalid input NURBS surface.
and the NURBS To Polygons
operation will not be successfully performed. The resulting polygonal
object will continue to be the last valid (computed) polygonal surface
that was visible.
- In some cases when converting multiple
NURBS patches to a single polygonal mesh you may notice strange
shading effects on the mesh. This is because of the normals. To
correct the shading due to normals, see
Fill holes in a polygon mesh.
- NURBS to polygon conversion does not
take the Fix Texture Warp attribute (which adjusts a texture’s UV
parameters so the texture does not rely on a NURBS object's UV parameterization)
into account.
