Class CreateTenons

java.lang.Object

de.mcp.cutcad.algorithm.CreateTenons

public class CreateTenons
extends java.lang.Object

Static class to calculate the outline (tenon structure) of an edge Can be used either for unconnected edges (one edge) or two connected edges so far. Uses the normal vectors of the shape, to whom these edges belong, from the edges themselves the 2D coordinates as well as their Array of Point2D, in which the outcome of the function (outline of the edge) is stored.

Method Detail

createOutlineOfEdge

public static void createOutlineOfEdge(Edge edge)

Calculates the outline of one (unconnected) edge Calculates the outline of one (unconnected) edge - which is basically just the line between the two points of this edge in the 2D view. It takes this two Point2D, and sets the internal Arraylist of Point2D (representing the outline of the edge) within edges to this two Point2D

Parameters:

edge - is the the edge which outline has to be modified

safeAngleBetween

private static float safeAngleBetween(Vector3D masterEdgeDirection,
                     Vector3D slaveEdgeDirection)

createOutlineOfEdge

public static void createOutlineOfEdge(Edge masterEdge,
                       Edge slaveEdge)

Calculates the outline of two (connected) edges Calculates the outline of two (connected) edges - using the addition of the thicknesses of both shapes times a factor for the length of a tenon, and then uses the angle between both shapes with these thicknesses to calculate how much each tenon of both edges have to be cut in or extruded to be able to assemble them on on side and have enough extrusion to be able to sandpaper these tenons for a smooth edge. Breaks down if either the material thickness is to big in relation to the size of a shape or the angle is far to sharp (both need to cut-ins which are bigger than possible). The resulting values are used to calculate an array of vectors which determine the outline of each edge with its tenons. These are then stored within the edge.

Parameters:

masterEdge - First Edge, which should be connected with

slaveEdge - , the second edge The order of these edges determines which edge starts with a cut in (the first one), while the other is extruded at the its ends.

getHeight

private static float getHeight(int thicknessMaster,
              int thicknessSlave,
              float angle)

createTenons

private static java.util.ArrayList<Vector2D> createTenons(Edge edge,
                                         float lengthOfATenon,
                                         float tenonHeight,
                                         float tenonDepth,
                                         int numberOfTenons,
