Posting some work from my upcoming smoking animation. I’ve been busy modeling out lungs and alveoli. Here is a still image rendered from my 3D scene, where the viewer is able to see the interior alveolar bundles.The 3D models have been modeled and textured in Maya. So far the textures have included surface shaders and bump mapping to give each alveolar bundle a nice cellular texture. The next step is to come up with textures emulating diseased and damaged alveoli caused by smoking.
