Level

dropdown

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

checkbox

Snaps the last level of subdivision to the limit surface.

Use Source

checkbox

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

Force Subdivision

checkbox

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

Scheme

dropdown

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

dropdown

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

dropdown

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

dropdown

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

dropdown

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.

OK

button

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

button

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.
