Subdivide Dialog

The Subdivide dialog is described below with functions for how to access it. A list of the controls on the dialog can be found in the table below.

What It Does

Invoked by the object subdivision commands, the Subdivide dialog box lets you specify options for how an object's mesh is further divided.

How to Access It

Menubar | Objects > Subdivide

Right-click | Objects Palette > Subdivide

Objects Palette| Subdivision| Subdivide

Subdivide Dialog Fields



What it does

Opens this dialog box




Indicates how dense the mesh is, once divided, with 3 being the highest level of subdivision. The number of subdivided quads or triangles for each level depends on the Subdivision Scheme used.



Snap to Limit Surface


Snaps the last level of subdivision to the limit surface.



Use Source


Uses subdivision options (Scheme and rules) from the source geometry file.



Force Subdivision


When enabled, Mari forces subdivision of the geometry no matter how the subdivision flags are set.





The subdivision method that you want to use when subdividing the object:

Catmull Clark - Mari uses the Catmull-Clark subdivision method when subdividing a mesh.

Loop - Mari uses the Loop subdivision method when subdividing a mesh. Loop subdivision supports meshes consisting of only triangles.

Bilinear - Mari uses the Bilinear subdivision method when subdividing a mesh.



Boundary Interpolation


Specifies how the boundary edges and vertices are interpolated.

None - no boundary edge interpolation should occur, instead boundary faces are tagged as holes so that the boundary edge-chain continues to support adjacent interior faces but is not considered to be part of the refined surface.

Sharpen edges - all the boundary edge-chains are sharp creases, boundary vertices are not affected.

Sharpen edges and corners - all the boundary edge-chains are sharp creases and boundary vertices with exactly one incident face are sharp corners.



Face Varying Linear Interpolation


Specifies the face varying linear interpolation rule:

None - smooths everywhere the mesh is smooth.

Corners only - sharpens (linearly interpolate) corners only.

Corners plus1 - Corners only + sharpening of junctions of 3 or more regions.

Corners plus2 - Corners plus1 + sharpening of darts and concave corners.

Boundaries - linear interpolation along the boundary edges and corners

All - linear interpolation of everywhere (boundaries and interior).



Creasing Method


Interpolates the sharpness of incident edges:

Uniform - applies regular semi-sharp crease rules.

Chaikin - applies Chaikin semi-sharp crease rules. Chaikin's curve subdivision algorithm improves the appearance of multi-edge semi-sharp creases with varying weights.



Triangle Subdivision


Rule added to the Catmull-Clark scheme that can be applied to all triangular faces:

Default - default Catmull-Clark scheme weights.

Smooths - smooths triangle weights.





Click to subdivide the object and display a subdivision progress bar.

The subdivision Level chosen is applied in the Viewer when the progress bar is finished.



In Background


Click to subdivide the object using a background process, no progress bar is displayed.

The subdivision Level must be applied manually in the Objects palette when the running man icon disappears.
