GEOTAR-Media is a Russian publishing group specialized in the medical literature. Being one of the largest medical publishing houses in Russia, GEOTAR-Media uses the latest digital technologies, uses audio and video materials, and interactive development for learning. The used systems have no analogs in Russia and fully comply with international medical standards.
The company has started cooperation with our team to develop a 3D model of a patient. By design, the virtual person should have specific height, weight, and symptoms that are to be represented in the model. Color of hair, eyes, and clothing details are to be chosen at the discretion of the developers. The code name of the virtual patient is Valera. He is 59 years old man with class I obesity. There also should be slight redness of the face and a scar after appendectomy. Though his face is extremely realistic, it is not a copy of any real person’s face.
As it was required, we created Valera’s clothes and hair different from the source model. We developed several types of animation depending on the physical position in space and clothing, which makes the model look like the person breathes, blinks, and has slight facial expressions. Thus, Valera has the same movements as a real person in a static position when examined by a doctor. Places of bending of the limbs are displayed correctly while moving.
The task required the work of a 3D modeler, 3D animator, and software engineer. The full term of the model creation was 35 days. The work that was done includes 3D modeling, texturing, rigging, animation, and setting up a demo scene to demonstrate the product. It also can be used as a base for software development. We created a demo scene basing on modified by client Three.js application. Our team has reached the set goal; the model functions correctly with Three.js. Yet, the client can improve textures and light by making a slight adjustment to the application code.
