Modelling and Rendering of Human Skin

Ovaj rad obrađuje razne metode izrade 3D modela ljudskog lica, te komponente pri izradi sjenčara koji simulira realistično reagiranje kože na utjecaj svijetla. Prvi dio rada sadrži detaljan pregled postupaka korištenih pri izradi 3D modela unutar programskog alata Blender, uz izradu modela i sjenčara oka, neophodnog za realistično prikazivanje ljudskog lica. Također, prikazani su postupci izrade tekstura, kasnije korištenih pri izradi sjenčara, unutar programskog alata Blender i alata za uređivanje slika GIMP. Drugi dio rada objašnjava građu kože, te kako koža reagira na nadolazeću zraku svjetlosti. Završni dio rada obuhvaća izradu komponenata sjenčara koji simulira realistično reagiranje kože na utjecaj svjetlosti, te završni prikaz modela napravljenog unutar ovog rada.This paper processes various methods of making 3D model of human face, and components used to make shader that will, in a realistic way, simulate how the skin reacts upon the impact of light. First part of this paper contains detailed review of procedures used for making the 3D model inside programming tool Blender, as well as making model and shader of the eye, which is required for making realistic appearance of human face. Also, it was shown how to make textures, later used in developing shader, inside programming tool Blender and image editing tool GIMP. Second part of this paper explains the composition of the skin and how it reacts with incoming light ray. The final part of this paper encapsulates development of components used in shader that simulates realistic skin behaviour upon light impact, as well as final render of model made inside this paper
