Class Slice

java.lang.Object

net.imglib2.mesh.alg.zslicer.Slice

All Implemented Interfaces:

Iterable<Contour>, Collection<Contour>

public class Slice
extends Object
implements Collection<Contour>

Class that represents the intersection of a closed 3D mesh (manifold and two-manifold) with a plane. The slice is made of a collection of several closed Contours. They are sorted by decreasing area.

xRayCast

public void xRayCast(double y,
                     gnu.trove.list.array.TDoubleArrayList x,
                     gnu.trove.list.array.TDoubleArrayList nx,
                     double yScale)

Computes the position of the intersection of this slice (as a contour collection) with the ray parallel to the X axis and of ordinate y, and measure the projected normal value at these intersections.

Parameters:

y - the ordinate of the ray to cast.

x - an array in which to store the intersection position. Reset by this call. Is sorted by increasing X value.

nx - an array in which to store the projected normal value at the intersections. Reset by this call.

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

xRayCast

public void xRayCast(double y,
                     gnu.trove.list.array.TDoubleArrayList x,
                     double yScale)

Computes the position of the intersection of this slice (as a contour collection) with the ray parallel to the X axis and of ordinate y.

Parameters:

y - the ordinate of the ray to cast.

x - an array in which to store the intersection position. Reset by this call.

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