Method Detail

smooth

public static java.util.List smooth(java.util.List orig,
                                    float K)

If the Content instance wraps a mesh, smooth it by the fraction K (0, 1).

Parameters:

orig -

K -

Returns:

smooth2

public static java.util.List smooth2(java.util.List<Point3f> orig,
                                     int iterations)

Implemented Blender-style vertex smoothing. See Blender's file editmesh_mods.c, at function "static int smooth_vertex(bContext *C, wmOperator *op)" What it does: 1. For each unique edge, compute the average of both vertices and store it in a Point3f. Also increment a counter for each vertex indicating that it has been part of an averaging operation. If the vertex is again part of an averaging operation, just add the new average to the existing one. 2. For each unique vertex, computer a factor as 0.5/count, where count is the number of times that the vertex has been part of an averaging operation. Then set the value of the vertex to 0.5 times the original coordinates, plus the factor times the cumulative average coordinates. The result is beautifully smoothed meshes that don't shrink noticeably. All kudos to Blender's authors. Thanks for sharing with GPL license. Taken from ImageJ 3D Viewer
