1. A method of modeling a three-dimensional object, comprising:

  • generating a model of a three-dimensional surface of the object from a second plurality of points that define a coarse digital representation of the three-dimensional surface and a texture map containing information derived by mapping points within the texture map to a fine digital representation of the three-dimensional surface that is defined by a first plurality of three-dimensional colored points, by;

    generating a quadrangulation of the three-dimensional surface from the first plurality of three-dimensional colored points;

    converting the quadrangulation into the second plurality of points; and

    determining the texture map for the coarse digital representation of the three-dimensional surface by determining for a first texel in the texture map a respective texel coordinate that identifies a first spatial point on the coarse digital representation of the three-dimensional surface and projecting the first spatial point to a first object point on the fine digital representation of the three-dimensional surface.
