Smooth and Decimate

Clicking this button allows smoothing and decimating selected meshes, or all visible meshes if no meshes are selected as follows.

Firstly a dialog window is pop up to show the following configuration:

Smoothing Iterations

Each iteration of smoothing adjusts point coordinates using Laplacian smoothing. The effect is to "relax" the mesh, making the cells better shaped and the vertices more evenly distributed. If iterations is 0, then no smoothing is performed.

Decimating Algorithm

Decimating reduces the number of triangles in a triangle mesh, forming a good approximation to the original geometry.

Three algorithms are provided. The 2nd and 3rd algorithms uses a parameter "Decimating Target Reduction" which specifies how much the triangles are reduced.

Finish or Cancel

Click the "Finish" button to perform the operation (smooth and then decimate); click the "Cancel" button to cancel the operation.

Automatic Configuration

If "Automatic Configuration" is checked, the configuration dialog window will not be displayed and its current setting will be used directly for future decimating and smoothing operation. This can be changed using the Configuration menu.
