1. A method comprising:
receiving positional measurements for a plurality of points of a physical object;
generating a 3D model of the physical object with a plurality of primitives that are defined in a 3D space based on the positional measurements;
receiving an image of the physical object that captures different intensities with which the plurality of points reflect a plurality of electromagnetic spectrum bands;
determining that the intensities with which a set of points from the plurality of points captured in the image reflect a set of the plurality of electromagnetic spectrum bands match a spectral signature of a particular material;
determining that the particular material absorbs a first electromagnetic spectrum band and reflects a second electromagnetic spectrum band of the plurality of electromagnetic spectrum bands;
adjusting colors that are represented for the set of points in the image by retaining effects that the intensities with which the set of points reflected the first electromagnetic spectrum band have on the colors and by removing effects that the intensities with which the set of points reflected the second electromagnetic spectrum band have on the colors; and
defining the 3D model to differ from the captured image of the physical object by removing lighting effects on colors of the physical object captured by the image from the 3D model, wherein defining the 3D model comprises mapping adjusted colors that are represented for the set of points in the image to a set of the plurality of primitives that are defined in the 3D space based on the positional measurements received for the set of points.
