Properties

Optional Algorithm

Algorithm?: "IG1" | "Blender1" | "Keys1"

The deformation algorithm. Allowed values are: "IG1" - The initial algorithm based on Lucas Majerowics' Mean Value Coordinates. http://hecodes.com/2016/07/mesh-manipulation-using-mean-values-coordinates-in-three-js/ This is default, if no (valid) algorithm is specified. "Blender1" - Blender's deformation algorithm, reference Blender 2.82 A, Linear "Keys1" - Shape-key based deformation using an external data file providing the keys.

Optional Maximum

Maximum?: number

Maximum value for missing coordinate in 2-dim deformations.

Optional Minimum

Minimum?: number

Minimum value for missing coordinate in 2-dim deformations.

Optional Parameters

Parameters?: Record<string, string>

Optional parameters that are by definition, algorithm-specific. Blender1: "X" | "Y" | "Z": "Linear" | "Cardinal" | "CatmullRom" | "BSpline"

Times

Times: number[]

Relative, strictly monotonic increasing time values. Must start with 0 and --if more than one entry--end with 1.

Optional Type

Type?: "XY" | "YZ" | "XZ" | "XYZ"

The lattice type. For efficiency reasons, there are subsets of XYZ. Legal values are: "XY" - x and z are provided "YZ" - y and z are provided "XZ" - x and z are provided "XYZ" - x, y and z are provided (default)

Values

Values: number[]

The lattice values: [t[Z[Y[X [x] [y] [z]]]]

Optional X

X?: number

Lattice size in x direction.

Optional Y

Y?: number

Lattice size in y direction.

Optional Z

Z?: number

Lattice size in z direction.
