Path3d

class Path3d(val points: List<Vector3>, val closed: Boolean)

A list of 3D points (Vector3). This class was first created, so that ExtrusionBuilder could extrude along an arbitrary 3D path.

To construct a Path, consider using Path3dBuilder, which supports straight lines and bezier curves.

Constructors

Path3d

constructor(points: List<Vector3>, closed: Boolean)

Properties

closed

val closed: Boolean

points

val points: List<Vector3>

size

val size: Int

Functions

extend

fun extend(by: Double): Path3d

Extends the ends of the path by the given amount. This only make sense for open paths. It can be useful when using an extrusion along a path with a hole through the middle. e.g.

get

operator fun get(i: Int): Vector3

Allows array-like access, where the index is rolled around, so that index -1 is the same as size-1 and also index size is the same as index 0 etc. This is particularly useful when you have an index, and want to find the next or previous. You can safely add or subtract without fear of IndexOutOfBoundsExceptions.

roundAllCorners

fun roundAllCorners(radius: Double): Path3d

fun roundAllCorners(radius: Double, sides: Int?): Path3d

Note, unlike Shape2d, a Path is not closed, i.e. it is NOT a ring of points

roundCorner

fun roundCorner(cornerIndex: Int, radius: Double): Path3d

fun roundCorner(cornerIndex: Int, radius: Double, sides: Int? = null): Path3d

toFace

fun toFace(): Polyhedron
