1. A method comprising:
obtaining a 3D point cloud, at least one point of said 3D point cloud comprising at least one component relative to a haptic feature, wherein said haptic feature belongs to a set of haptic features comprising rate-hardness, contact area spread rate, dynamic stiffness, local surface orientation, local indentation, stroke spectral response, kinetic friction, static friction, stick-slip and thermal profile;
projecting a depth component and said at least one component relative to a haptic feature of points of the 3D point cloud onto patch pictures; and
packing said patch pictures in an atlas image.
