Decimate

This effect will reduce the number of faces of a mesh while trying to preserve its shape.

Note

This will triangulate the mesh first.

Input

polygonal mesh

Output

polygonal mesh

VTK classes

vtkQuadricDecimation, vtkTriangleFilter

Options

../_images/properties-decimate.png
Target ratio

Ratio of input : output triangles. For example, Target ratio = 0.2 means 80% reduction of triangle count, with the decimated mesh only having 20% triangles compared to the original.

Preserve volume

When this option is on, mesh shape will be more accurately preserved, at cost of performance.
