Algorithm for Visualizing Volumetric Pores and Wrinkles Based on a Displacement Map

Abstract

The article proposes an approach to developing an algorithm for visualizing realistic skin micro-relief, focusing on the creation of volumetric pores and wrinkles. Realistic skin representation is crucial in fields such as animation, video games, and cinematography, where close-up shots require accurate skin texture rendering. Traditionally, creating such detailed textures was a manual and time-consuming process. This paper proposes a procedural approach using displacement maps, which accelerates the process and enhances the scalability of pore and wrinkle texture generation while allowing flexible parameter adjustments.
The method presented in the article begins with initializing a high-resolution displacement map, on which pore and wrinkle textures are sequentially created using mathematical functions. Pores are visualized as circular depressions with smooth transitions from center to edge, while wrinkles are modeled as linear structures with parameters including depth and width. To achieve a natural appearance, Perlin noise is applied to the texture, introducing irregularities that make pores and wrinkles more lifelike. The article concludes with the results of an experiment with parameter adjustments.
The proposed algorithm allows precise control over pore and wrinkle parameters, such as depth, width, and falloff, enabling a high degree of realism. Its efficiency and scalability make this method suitable for generating realistic facial micro-relief textures.
