Access Lattice Points via Script about deform

[keenanwoodall]

LatticeDeformer exposes GetControlPoint and SetControlPoint helper methods as well as a flat float3[] ControlPoints array.

Here's an example script that generates game-objects for the control points.

public class SetControlPoints : MonoBehaviour
{
    public LatticeDeformer deformer;

    private Transform[] controlPointAnchors;
    
    private void Start()
    {
        controlPointAnchors = deformer.ControlPoints.Select(p =>
        {
            var newAnchor = GameObject.CreatePrimitive(PrimitiveType.Cube);
            newAnchor.name = "Control Point";
            newAnchor.transform.SetParent(deformer.transform);
            newAnchor.transform.localPosition = p;
            newAnchor.transform.localScale = Vector3.one * 0.1f;
            return newAnchor.transform;
        }).ToArray();
    }

    private void Update()
    {
        for (var i = 0; i < controlPointAnchors.Length; i++)
        {
            var anchor = controlPointAnchors[i];
            if (!anchor.hasChanged)
                continue;
            anchor.hasChanged = false;
            deformer.ControlPoints[i] = deformer.transform.InverseTransformPoint(anchor.position);
        }
    }
}

Thanks for that! It works very well. 👍

I was thinking if it would be possible to have a smoother Deformation. Currently everything is Linear, Point to Point.

Like a Bezier Curve from Point to Point so the Start and End are tangentially.

I just pushed simple hermite smoothing to the develop branch 9b2d716.
Here's what simple smooth-step smoothing looks like

I think the proper solution would be to do some sort of tricubic interpolation like catmull-rom, but that would be nontrivial :P
