Class StretchPoint

Example

    // StretchPoint describes a single control point for a FaceStretchVisual feature.
    //   index  — vertex index into the face mesh the stretch is anchored to.
    //            See the face-mesh vertex layout in the Lens Scripting reference:
    //            https://developers.snap.com/lens-studio/api/lens-scripting/classes/Built-In.FaceStretchVisual
    //   delta  — displacement applied to that vertex (local-space vec3).
    //   weight — blend amount applied to this point (0..1).
    const point = new Editor.Components.StretchPoint();
    point.index = 3; // vertex #3 on the face mesh
    point.delta = new vec3(0.5, 1.0, 0.0);
    point.weight = 0.75;

    // Points are typically assembled into an array and handed to
    // FaceStretchVisual.updateFeaturePoints(featureName, points).
    const points: Editor.Components.StretchPoint[] = [point];
    console.log(`StretchPoint feature: ${points.length} point(s), first at vertex ${points[0].index}`);
