Decimating a Polygonal Mesh

This task shows you how to decimate a polygonal mesh, in order to reduce the triangle count of a polygon.
Open the Bunny1.CATPart document.

  1. Click Decimate and select a polygonal mesh.

    The Decimate dialog box is displayed:

  2. Check the type of decimation you want to apply:

    • Chordal Deviation, or

    • Edge Length

  3. Click Apply.

    The decimation is computed. The counts of triangles are updated in the Current Triangle Count.

  4. Either press OK to validate the decimation and exit the action;
    or press Apply to start continue the decimation with the same values or new ones;
    or press Cancel to exit the action and revert to the initial model.
