Mesh Post Processing

The algorithm allows to modify the mesh by sequentially applying basic processing steps: smoothing, decimation, etc.

Input

A single mesh.

Output

None. The input mesh will be modified by the algorithm.

Description

The following processing options are available to the user:

  • Smooth: Perform Laplacian smoothing of the mesh. Number of smoothing iterations should be specified in the field Iterations.
  • Decimate: Perform decimation of the mesh. The value in Max. edge length sets the constraint on the maximum allowed edge length. The checkboxes Preserve curvature and Preserve vertex colors specify whether corresponding properties of the mesh should be preserved during the decimation.
  • Color: Change the color appearance of the mesh. Sliders Brightness, Contrast and Gamma can be used to tune the color appearance of the mesh. Check the Use HSV color space checkbox if the HSV color space is preferred.
  • Clean: Clean the mesh by removing connected components with the specified area. Sliders Minimum surface area and Maximum surface area determine the range of areas [minArea, maxArea]. All connected components, which have the area outside of this range, will be deleted. The button Select largest component can be used to automatically select the area range such that only the largest component remains after the cleaning.
  • Crop: Crops the mesh by removing faces that are outside (or inside if Discard data inside box is ticked) of the cropping box. Use manipulators Translate, Rotate and Scale to adjust the cropping box. Cap hole can be used to close the holes which resulted from cropping.
  • Remove edges: Remove faces that are on the border of the mesh. Value in Layers is used to adjust the number of border layers to be removed.
  • Merge close vertices: Merge close vertices, the distance between which is below the Threshold, into one vertex. This option is useful for removing duplicated vertices.
  • Fill holes: Fill holes in the mesh by performing Poisson reconstruction.
  • Invert normals: Invert the direction of mesh vertex normals.
  • Automatic alignment: Attempt to automatically orient the mesh in such a way that its z-axis is perpendicular to the ground.

The buttons Undo and Redo can be used to undo and redo the changes made to the mesh. When pressed, the button Reset will reset the mesh to its initial state.
