Class LinePoints

java.lang.Object

frink.graphics.LinePoints

public class LinePoints
extends java.lang.Object

This class contains routines to find the points along a line in 3D. It can generate a tool path for drawing in a VoxelArray, specifically with the VoxelArray.paintAlongPath(Point3DIntList, VoxelArray, int, int, int) method.

public static Point3DIntList line3DInt(Point3DInt p1,
                                       Point3DInt p2)

Creates a vector of Point3DInt consisting of the integer points on a line between p1 and p2.

line3DInt

public static Point3DIntList line3DInt(LineSegment3DFloat line)

Creates a vector of Point3DInt consisting of the integer points on a line between p1 and p2.

line3DInt

public static Point3DIntList line3DInt(int x1,
                                       int y1,
                                       int z1,
                                       int x2,
                                       int y2,
                                       int z2)

Creates a vector of Point3DInt consisting of the integer points on a line between p1 and p2. This uses Bresenham's algorithm for a 3-D line. See Bresenham's Algorithm
