Subdivision > Reform
Generates a subdivision object that conforms to the shape of a selected mesh object. Use this tool to quickly generate a surface model from scanned meshes or other triangulated mesh objects.
Access this tool from the Subdivision tool palette by doing either of the following:
- Clicking this icon:
.
- Right-clicking Subdivision and selecting Subdiv> Reform.
Before using the tool to generate a subdivision model, investigate the source mesh for obvious irregularities, such as unwanted holes in the topology. For more information, see the following:
Prepare Mesh
Reduce to %
Sets the percent of the source mesh topology used to generate the shape of the subdivision model. The higher the value, the greater the amount of the mesh topology is used in the calculation, which results in a more accurate representation of the mesh shape. For example, a value of 50 reduces the input mesh to 50 percent of its original triangle number before Alias begins generating the subdivision object.
Depending on the complexity of the input mesh, higher Reduce to % values typically result in slower performance.
Topology
Target Face Number
Sets the number of subdivision faces generated in the output object. The higher the value, the higher the resolution of the subdivision model. This value is an approximate target value. For example, a value of 50 results in a subdivision object with between 40 and 60 quad faces.
Refinement
Subdivisions
Use this option to control the overall resolution of the output subdivision object. When Subdivision is increased by a value of 1, Alias divides each face into four faces. If the Target Face Number is set to 50, increasing Subdivision from a value of 1 to 2 increases the number of subdivision faces to 200.
The higher the Subdivision value, the closer the output subdivision object resembles the shape of the source mesh.
Curvature Bias
Use this setting to increase the distribution of CVs to areas of higher curvature, which can improve the overall shape of the resulting subdivision model. At lower values, the resulting CV layout is more uniform. Increasing this value changes the layout CV to one that distributes a higher number of CVs to areas with more curvature. Typically, higher values take longer to compute.
