Building an integumentary system hyperspectral model for avatars

Abstract

In this paper we transform the results of a hyperspectral skin reflectance model into RGB values to simulate the color of skin under various biological circumstances. The amount of different chromophores in the skin can be adjusted within the model to simulate circumstances such as elevated blood levels in the cheeks caused by blushing, the draining of blood from the face caused by fear, or the bluish tint of the skin caused by a lack of oxygen. The melanosome level in the epidermis can also be adjusted to simulate different levels of skin darkness and show how increased levels of melanosomes reduce the influence of other chromophores in skin.
