According to an aspect, there is provided a method comprising controlling a structural light source of a modelling arrangement to produce a diffraction pattern of a known geometry on a surface to be modeled, the diffraction pattern accurately complying with a mathematical-physical model and wherein beam output angles of the diffraction pattern are accurately known based on the mathematical-physical model; recording a first image of the surface comprising the diffraction pattern with a first camera and a second image of the surface comprising the diffraction pattern with a second camera substantially simultaneously; determining a point cloud comprising primary points from the diffraction pattern visible in the first image; identifying the corresponding primary points from the second image; and using each primary point of the point cloud in the first and second images as an initial point for search spaces for secondary points in the first and second images.
