Class SurfaceAttributeInterpolation

Allows to interpolate an attribute (scalar, vector3 or matrix33) from vertices to triangles, or from triangles to vertices

const s = new arch.Surface(...)
const displ = [...] // values at vertices

const I = new arch.SurfaceAttributeInterpolation(s)
const displAtT = I.fromVerticesToTriangles(displ)

const s = new arch.Surface(...)
const displ = s.displ(true, true) // displ at T

const I = new arch.SurfaceAttributeInterpolation(s)
const displAtV = I.fromTrianglesToVertices(displ)
