public static CSG points(eu.mihosoft.vvecmath.Vector3d dir,
                         eu.mihosoft.vvecmath.Vector3d... points)

Extrudes the specified path (convex or concave polygon without holes or intersections, specified in CCW) into the specified direction.

Parameters:

dir - direction

points - path (convex or concave polygon without holes or intersections)

Returns:

a CSG object that consists of the extruded polygon

points

public static CSG points(eu.mihosoft.vvecmath.Vector3d dir,
                         java.util.List<eu.mihosoft.vvecmath.Vector3d> points)

Extrudes the specified path (convex or concave polygon without holes or intersections, specified in CCW) into the specified direction.

Parameters:

dir - direction

points - path (convex or concave polygon without holes or intersections)

Returns:

a CSG object that consists of the extruded polygon

points

public static java.util.List<Polygon> points(eu.mihosoft.vvecmath.Vector3d dir,
                                             boolean top,
                                             boolean bottom,
                                             eu.mihosoft.vvecmath.Vector3d... points)

Extrudes the specified path (convex or concave polygon without holes or intersections, specified in CCW) into the specified direction.

Parameters:

dir - direction

points - path (convex or concave polygon without holes or intersections)

Returns:

a list containing the extruded polygon

points

public static java.util.List<Polygon> points(eu.mihosoft.vvecmath.Vector3d dir,
                                             boolean top,
                                             boolean bottom,

Extrudes the specified path (convex or concave polygon without holes or intersections, specified in CCW) into the specified direction.

Parameters:

dir - direction

points1 - path (convex or concave polygon without holes or intersections)

combine

public static CSG combine(Polygon p1,
                          Polygon p2)

Combines two polygons into one CSG object. Polygons p1 and p2 are treated as top and bottom of a tube segment with p1 and p2 as the profile. Note: both polygons must have the same number of vertices. This method does not guarantee intersection-free CSGs. It is in the responsibility of the caller to ensure that the orientation of p1 and p2 allow for intersection-free combination of both.

Parameters:

p1 - first polygon

p2 - second polygon

Returns:

List of polygons

combine

public static java.util.List<Polygon> combine(Polygon p1,
                                              Polygon p2,
                                              boolean bottom,
                                              boolean top)

Combines two polygons into one CSG object. Polygons p1 and p2 are treated as top and bottom of a tube segment with p1 and p2 as the profile. Note: both polygons must have the same number of vertices. This method does not guarantee intersection-free CSGs. It is in the responsibility of the caller to ensure that the orientation of p1 and p2 allow for intersection-free combination of both.

Parameters:

p1 - first polygon

p2 - second polygon

bottom - defines whether to close the bottom of the tube

top - defines whether to close the top of the tube

Returns:

List of polygons

isCCW

public static boolean isCCW(Polygon polygon)

Indicates whether the specified polygon is defined counter-clockwise.

Parameters:

polygon - polygon

Returns:

true if the specified polygon is defined counter-clockwise; false otherwise
