Package net.imglib2.mesh.alg.zslicer

Class ZSlicer

java.lang.Object

net.imglib2.mesh.alg.zslicer.ZSlicer

public class ZSlicer
extends Object

Slice a mesh by a Z plane. Only works for meshes that are two-manifold (otherwise contours are not closed).

Round vertices positions and plane position to even and odd multiples of a small fraction of the mesh size, so that they don't intersect. Build contours by iterating from an intersecting edge to the adjacent one, with a determined orientation (CCW for interior contours). The contours returned "know" whether they limit the interior or exterior of the mesh.

Method Detail

slices

public static List<Slice> slices(Mesh mesh,
                                 double[] zs,
                                 double zScale)

slice

public static Slice slice(Mesh mesh,
                          double z,
                          double zScale)

Slice a mesh by a Z-plane.

Parameters:

mesh - the mesh to slice. Not modified.

z - The Z position of the XY plane to slice through.

zScale - some scale in Z (such as the pixel size in Z), used to shift the vertices and Z-plane position by a small fraction of this size.

Returns:

the section of the mesh at the specified Z position, returned as a collection of Contour objects.
