Representing the human anatomy with a 3d model can be daunting for many even expert 3d modelers. These 3d models are used to display the dynamics of breakthrough surgical procedures or to put together instructional diagrams to show health practitioners about how to use a medical device.
When looking to begin the 3d modeling and rendering process of the human anatomy, the first thing that a 3d modeler should do it get familiar with the basic human anatomy and also get a list of the organs of the body that can be obtained by using an existing stock 3d model.
Keep in mind that if you are not a doctors or have studied anatomy intensively some of the organs might not be known to you.
A typical human anatomy 3d model includes one or all of the important body systems, and if done properly will be organized accordingly, as follows:
Muscular and Skeletal. It provides us with great protection and structural support for other soft tissue and organs. These include organs such as the bones, muscles, cartilage, ligaments, and tendons. Also, if you plan to rig the character or 3D model of people, it is important that you are familiar with the motions and human locomotion especially the Musculo-skeletal system.
Nervous. The Nervous System 3D models can be quite complex because of the inherent complexity of our own Nervous system. It includes the network of nerves, the brain, and spinal cord. and they run throughout our whole body. They monitor electrical impulses back and forth from the brain which allows us to interact and respond to our environment.
Our own Digestive system has the role of processing food for energy and removing waste from our own bodies. The major organs that are involved in doing this include the stomach, esophagus, liver, gallbladder, pancreas, intestines, rectum and anus.
The Endocrine System Almost all of the 3D models that support the Endocrine system will be assembled by glands and can possibly include the hypothalamus, pituitary, pineal, thyroid, parathyroid, and adrenal glands, which allow important signals and communication within the body via hormones.
Lymphatic: Lymphatic organs include the spleen, appendix, tonsils, bone marrow, thymus, adenoids, lymph nodes, and Peyer’s patches. The Lymphatic system transfers lymph amongst tissues and the bloodstream. A Human Anatomy 3D Model will include some if not all of the organs that make up the lymphatic .
The Urinary System The urinary System includes all the organs, tubes, muscles, and nerves that interact to create the urine, store it, and move it out of our own bodies. The 3d model of the urinary system will include the both kidneys, the urethra, the penis (for males only) and both ureters..
Our own Immune System plays a very essential role in protecting us from disease. 3D Models help visualize this important function. This group includes 3d models of the spleen, thymus, the lymph noes and vessels. It performs this important function by identifying and killing pathogens that come in contact or enter the body or grow within our own body, like tumor cells.
Reproductive. Our own Reproductive system allows us to procreate. The male reproductive organs that will make up male 3d model will include the penis, seminal vesicles, prostate and the testes. A female anatomy 3D model will include all of the key female reproductive organs including the ovaries, vagina, uterus and the fallopian tubes.
The Respiratory System includes the lungs, larynx, bronchi, pharynx, diaphragm. Human anatomy 3d models often group these together or break them up by sections of the body, like upper body organs and lower body organs.
If you go with a very detailed and accurate 3d model of the human anatomy, then you can expect to have a complex but organised, because the human anatomy is studied and displayed as such. Most likely your animation or visualization will not need every single detail, but rather a lot of detail on a particular area and just the silhouette for the rest of the human body.
Remember that a ready made or even a custom human anatomy 3D model can greatly improve your 3D visualizations and animations while also saving you a lot of 3d modeling time and expense. For this reason, before going ahead with a particular 3D model it is best to always check the specs and its description and if possible download the video or previews.
Flat Pyramid 3D Marketplace focuses on distributing and customizing 3d. They have very good examples of realistic anatomy 3d models. Also, for a limited time only they are offering free download for some of their 3d models.
