pointsToStroke static method

])

Implementation

static BufferGeometry? pointsToStroke(List<Vector?> points, style, [int? arcDivisions, double? minDistance]) {
  // Generates a stroke with some witdh around the given path.
  // The path can be open or closed (last point equals to first point)
  // Param points: Array of Vector2D (the path). Minimum 2 points.
  // Param style: Object with SVG properties as returned by SVGLoader.getStrokeStyle(), or SVGLoader.parse() in the path.userData.style object
  // Params arcDivisions: Arc divisions for round joins and endcaps. (Optional)
  // Param minDistance: Points closer to this distance will be merged. (Optional)
  // Returns BufferGeometry with stroke triangles (In plane z = 0). UV coordinates are generated ('u' along path. 'v' across it, from left to right)
