This model includes detailed and anatomically correct close-up representation of the human lungs alveoli. The model includes intralobular bronchiole, respiratory bronchiole, pulmonary vein and artery, capillary network on surface of alveolus, alveoli and alveoli cross section.
The model is based on real images and anatomy books. The entire geometry is very clean. It is all poly and most quads with few triangles.
Most textures are 2k, some of them that are tiled are 1k or 512. There are total of 5 diffuse maps and 5 bump maps.
The lighting and render is done in maya 2011 using mental ray. All other formats include the geometry, standard materials and textures applied. Maya setup uses Sub Surface Scattering to get the flashy look. The render is rock solid and it takes from 2 to 5 minutes per frame on i5 machine (for the preview 1200x1200 image) which makes it VERY usable for Animations. No Global Illumination or Final Gathering used. The renders from the preview are not edited in any way in post, so what you see is what you get.
