Class Path

constructor

• new Path(
      travelType: PathType,
      extrusionWidth?: number,
      lineHeight?: number,
      tool?: number,
  ): Path

  Creates a new Path instance

  Parameters

  • travelType: PathType

    Type of path movement

  • OptionalextrusionWidth: number

    Width of extruded material, when known

  • OptionallineHeight: number

    Height of extruded line, when known

  • tool: number = 0

    Tool number (default: 0)

  Returns Path

  Remarks

  A path's own dimensions come from slicer metadata and take precedence at render time; a path without them falls back to the renderer's global setting, then to the built-in defaults.

vertices

• get vertices(): number[]

  Gets the path's vertices as a flat array of numbers

  Returns number[]

  Array of vertex coordinates in [x,y,z] order

addPoint

• addPoint(x: number, y: number, z: number): void

  Adds a new point to the path

  Parameters

  • x: number

    X coordinate

  • y: number

    Y coordinate

  • z: number

    Z coordinate

  Returns void

checkLineContinuity

• checkLineContinuity(x: number, y: number, z: number): boolean

  Checks if a point continues the current line

  Parameters

  • x: number

    X coordinate to check

  • y: number

    Y coordinate to check

  • z: number

    Z coordinate to check

  Returns boolean

  True if the point matches the last point in the path

geometry

• geometry(
      opts?: { extrusionWidthFallback?: number; lineHeightFallback?: number },
  ): BufferGeometry

  Creates a 3D geometry from the path

  Parameters

  • opts: { extrusionWidthFallback?: number; lineHeightFallback?: number } = {}

    Geometry options

    • OptionalextrusionWidthFallback?: number

      Width for a path that carries none of its own

    • OptionallineHeightFallback?: number

      Height for a path that carries none of its own

  Returns BufferGeometry

  BufferGeometry representing the path

  Remarks

  Dimensions resolve per path: the path's own value (from slicer metadata) wins, then the caller's fallback (the renderer's global setting), then the built-in defaults.

line

• line(): LineSegmentsGeometry

  Creates a line geometry from the path

  Returns LineSegmentsGeometry

  LineSegmentsGeometry representing the path

path

• path(): Vector3[]

  Converts the path's vertices to an array of Vector3 points

  Returns Vector3[]

  Array of Vector3 points

splitLastSegment

• splitLastSegment(): { body: Path; segment: Path }

  Splits the path into its final segment and the body that precedes it.

  Returns { body: Path; segment: Path }

  The last two points as segment, and everything up to and including the segment's first point as body (null when the path is a single segment). Both carry this path's travel type, extrusion settings and tool.

  Remarks

  Requires at least two points; used to draw the final segment of a print in its own highlight color while the rest of the path keeps another one.
