Automated Creation of Unique Editable Textures for Three-Dimensional Models of Archaeological Artefacts

Abstract

The article is devoted to the description of the algorithm for obtaining a complete model from a colourless model of a stone and its prototype image with a material that allows you to manually make changes for greater detalization. Since it is often necessary to make some manual changes in the tasks of modelling archaeological objects, which necessarily requires special skills in working with complex software, as well as considerable time costs, the task was to implement an algorithm that facilitates this process. First, using an image of the object, PBR maps are created. After that, the UV map of the object is formed, and at the end, a unique PBR texture of the object is created. The algorithm was tested on a number of colourless models of stones and various images. At the output, we get an object wrapped in a texture obtained from the original image. Also, an extension for professional free software was created, allowing to make any additional changes in its texture if needed and get the desired result for the minimum number of user actions.
