maya tutorials polygon modeling subdiv proxy
In this tutorial, I am going to explain the smoothing of the polygon mesh
and the usage of the Subdiv Proxy.


For the explanation about polygon modeling, please refer to
Maya tutorials: polygon modeling (1) basic operation
Maya tutorials: polygon modeling (2) operation of the polygon mesh


maya tutorials polygon modeling subdiv proxy Smooth
maya tutorials polygon modeling subdiv proxy
Select a polygon mesh
Mesh > Smooth

maya tutorials polygon modeling subdiv proxy
The faces are subdivided and smoothed.

In the Channel Box, you see the history of the commands,
and you can specify the object's smoothness by setting
the Divisions value.

Or you can specify the Divisions value
in the option window of the Smooth command.
Mesh > Smooth

Select a polygon mesh
Proxy > Subdiv Proxy
A smoothed mesh are generated in the proxy mesh.

maya tutorials polygon modeling subdiv proxy
When you edit
(transform, rotate, scale the vertices, edges, and extrude, cut faces etc)
the outside polygon (proxy mesh),
the inside polygon (smooth mesh) is similarly edited like being smooth.

maya tutorials polygon modeling subdiv proxy
Because the inside polygon doesn't follow
if you transform, rotate, scale the outside polygon in the object mode,

maya tutorials polygon modeling subdiv proxy
you should transform, rotate, scale it in the component mode.

maya tutorials polygon modeling subdiv proxy
Open the option window
Proxy > Subdiv Proxy maya tutorials polygon modeling subdiv proxy

If you turn on Smooth Mesh In Layer
the smooth mesh is put in a display layer.
Moreover, Reference is set automatic and on,
and the layer enters the state of the reference (R mark).

maya tutorials polygon modeling subdiv proxy
Select the faces of the polygon mesh that are in -x,

maya tutorials polygon modeling subdiv proxy
delete them.
Select the polygon mesh in the object mode,

maya tutorials polygon modeling subdiv proxy
open the option window
Proxy > Subdiv Proxy maya tutorials polygon modeling subdiv proxy

Select
Mirror Behavior Full
Mirror Direction -X
Push the Smooth (or Apply) button.

maya tutorials polygon modeling subdiv proxy
When you edit the outside polygon (proxy mesh),
you can do modeling with symmetry kept.

maya tutorials polygon modeling subdiv proxy
When the vertices that should be x=0 has shifted as shown in the above figure,
you choose the vertices around x=0,

maya tutorials polygon modeling subdiv proxy
open the Component Editor
Windows > General Editors > Component Editor...

Specify the value of x coordinates for 0.

In Maya 2008 (or later), you can display the polygon meshes smooth
with pressing 1, 2, 3 keys.

maya tutorials polygon modeling subdiv proxy
1 key, original polygon.

maya tutorials polygon modeling subdiv proxy
2 key, original polygon (cage) and smooth.

maya tutorials polygon modeling subdiv proxy
3 key, smooth.

I'm a graduation student.We are suppose to do a project In computer Graphics.While surfing net for getting new ideas for our project I came across this site the tutorial provided in this link will be of great help in our project.
Thanks.

You're welcome.
I am glad to be able to help you.

nice one

can we keep original mesh along with smooth mesh ?

yes you can.
