“…Structural elements have been studied that provide material information for rendering, for example distribution of cortical and trabecular bone [DGBW09], and collagen fibre bundles in ligament [ECBH06]. Besides, in surgery simulation, the amount of blood and water on the bone surface has been used to generate wet surfaces as a means to enhance realism [KSS09].…”

The visual fidelity of realistic renderings in Computer Graphics depends fundamentally upon how we model the appearance of objects resulting from the interaction between light and matter reaching the eye. In this paper, we survey the research addressing appearance modelling of living human tissue. Among the many classes of natural materials already researched in Computer Graphics, living human tissues such as blood and skin have recently seen an increase in attention from graphics research. There is already an incipient but substantial body of literature on this topic, but we also lack a structured review as presented here. We introduce a classification for the approaches using the four types of human tissues as classifiers. We show a growing trend of solutions that use first principles from Physics and Biology as fundamental knowledge upon which the models are built. The organic quality of visual results provided by these Biophysical approaches is mainly determined by the optical properties of biophysical components interacting with light. Beyond just picture making, these models can be used in predictive simulations, with the potential for impact in many other areas.

“…Because PAH has many effects on passive vascular wall properties and composition [1–9], these effects should be captured within specific parameters of the constitutive model. The extracellular matrix protein elastin determines the low-stretch stiffness of the artery, and thus the pulmonary vascular input impedance [1].…”

“…These features are the J-shape stress-stretch curve, observed under the application of tensile loads, and the anisotropic nature, observed when loading in different directions [2, 5, 6]. The J-shape is due to the delayed engagement of the so-called collagen fiber bundles (CFB) [7–9]. CFB, common structures in fibrous tissue, such as tendon, artery, and skin, in the artery wall are tortuous [8] and lightly cross-linked [2].…”

A new constitutive model for elastic, proximal pulmonary artery tissue is presented here, called the Total Crimped Fiber Model. This model is based on the material and micro-structural properties of the two main, passive, load-bearing components of the artery wall, elastin and collagen. Elastin matrix proteins are modeled with an orthotropic neo-Hookean material. High stretch behavior is governed by an orthotropic crimped fiber material, modeled as a planar sinusoidal linear elastic beam, which represents collagen fiber deformations. Collagen-dependent artery orthotropy is defined by a structure tensor representing the effective orientation distribution of collagen fiber bundles. Therefore, every parameter of the total crimped fiber model is correlated with either a physiologic structure or geometry or is a mechanically-measured material property of the composite tissue. Further, by incorporating elastin orthotropy, this model better represents the mechanics of arterial tissue deformation. These advancements result in a micro-structural total crimped fiber model of pulmonary artery tissue mechanics which demonstrates good quality of fit and flexibility for modeling varied mechanical behaviors encountered in disease states.
