Reduces the number of polygons by collapsing edges.
To apply: Select one or more polygon mesh objects, polygon clusters, or polygons and choose Modify Poly. Mesh Polygon Reduction from the Model toolbar.
To redisplay: Select the reduced object, click the Selection button on the Select panel, then click the Polygon Reduction Op icon.
Allows you to use a weight map to control the amount of reduction in different areas. Connect or disconnect a weight map by right-clicking on the connection icon to the right of the Multiplier slider.
The cluster that contains the weight map must exist before you apply the Polygon Reduction operator. If you want to add or remove points from the cluster or paint weight strokes later, make sure you disable the Polygon Reduction operator first.
If Invert is on, areas in which the weight map has a low opacity are more likely to be reduced than areas with a high opacity. Areas with a weight of 1 are reduced last; they are essentially protected from reduction unless the reduction amount is so high that the other areas of the weight map cannot be reduced further.
Controls the priority given to preserving edges that meet the corresponding criteria. Setting a slider to its maximum value preserves the corresponding edges completely, and may prevent the operator from reaching the amount of reduction set on the General tab. Setting a value of 0 means that the criterion is not considered at all when reducing polygons. Turning a checkbox off is equivalent to setting a value of 0.
Biases the reduction process by taking into account value differences in other properties. A value of 0 ignores the attribute when considering an edge for reduction, while non-zero values set a weighted priority which is considered together with the edge's geometric energy.

Allows you to generate several versions of an object at different levels of detail. The operator precalculates the geometry for each version and caches the results. |
