The medical industry enjoys its wide use of technology, especially when it comes to learning about the human anatomy. Using human anatomy models to teach the several portions of the body to young people is a very accepted practice with proven benefits.
It is possible to use a 2d model for the purpose of demonstrating the parts of the human body. However, 3ds human modeling often gives you a more effective platform for discussing the human anatomy and its various systems.
Ways To Use A 3ds Human Model
Perhaps one of the biggest reasons why 3ds human models work is because of the three-dimensional nature itself. These kind of models provide the ability to view the body or areas of it in all different angles. You can use 3d human figures with 360-degree rotations, which allows you to locate even the smallest part of the human body provided that you have a clear and accurate depiction. Typically, viewing figures in solid forms which are what 3d human models are contrary to flat ones enable you to clearly see what you are looking at.
In essence, you can view the human person from the front, rear, and even top and bottom. This 3ds human modeling makes working much easier no matter which type of audience you are presenting to. One specific way the 3ds human might be used would be in a classroom setting where students can use the anatomy 3d model to study the human nervous system.
Several surgeons may also use 3d human models during medical procedures. These 3d human models can be used in a research lab to diagnose certain human ailments.
Learning Becomes Enjoyable With 3D Models
Constructing presentations also becomes easier when using 3ds human models. Teachers can implement the use of 3d models to engage high school students in the learning process, which helps young people visually make associations between the learned features of the body and the actual visual part on the 3d human. Labeling parts of the anatomy is a cinch with 3d human models as you can rotate the model with specialty 3d or presentation software. These 3d human models can be integrated into different types of presentation applications.
Presenters who are discussing medical topics with other colleagues or who are giving community presentations can also benefit from the 3ds human models. Instead of trying to make your audience understand what you’re talking about, a detailed presentation showing anatomy 3d models can help. In this instance, the phrase “a picture is worth a thousand words” stands true as you can perform a variety of animations with your presentation to enhance your audience’s understanding of the topic. 3d models make it easier to demonstrate an action that is difficult to verbally make sense of.
Working with these types of 3ds human models requires you to use a variety of file types and applications as well. For example, the .3ds file format is perhaps the most popular of the 3d modeling formats. In addition, converting from one three-dimensional file format to another is quite easy as there is software available that can automatically convert your 3d files to a .3ds format.
As you can see, there exists a diversity of medical uses for 3ds human models. Maybe you want to display how the cardiovascular system operates through a 3d model, display the bone and joint system, or easily illustrate the major parts of the human body using a full-scale person, a digitized 3ds human is beneficial to anyone within the medical field.
Face 3d modeling is done using stock or custom 3d models that are created with smooth meshes and a lot of details. They can also be done using high end capturing devices and software to get a model that is then further processed using 3d modeling software. Here we discuss the first approach.
You can cut down time and production costs if you purchase a 3d model from a 3d marketplace to use in your face 3d modeling and animation. Using a ready made 3d model will help you a lot during your face 3d modeling process. However, remember that when you use one that has already been made, you will have to add your own features and you will have to change it so it can be unique.
To start, lets look at the help you get when using this approach to start the process. Custom 3d models allow for an easier way to obtain the right proportions for the 3d face and also the necessary details that are needed to ultimately meet your needs for the face 3d modeling project.
There are many advantages when you decide to use a customized 3d model especially when you start the face 3d modeling process. Essentially, by taking this step you can get the realistic location of the eyes, eyebrows, face, mouth and other proportions.
Let’s me illustrate this with an example. When you need the licensing rights for a character, you will most likely need to get custom 3d models of characters. You can opt for getting a high quality one that is already made that is also highly realistic and may even include the necessary rigging or facial movements.
Bear in mind that to use the face 3d model or add a feature you will need to have specialized 3d modeling and rendering talents throughout the process of face 3d modeling in order for you to mesh it again and make it look like a human face. After all, a stock 3d model is not exclusive meaning you don’t own the rights. Therefore, it is not uncommon for you to have to alter it to meet your requirements or to make it a truly original face.
In addition, most face 3d modeling almost always involves further work particularly adding facial movements and emotions. In other words, most custom 3d models that involve any part of body need lots of additional manipulation to look real.
There are several methods you may use to create custom 3d models of human faces. If you are not an expert 3d modeler then it is best to get the services of one that specializes in this area. If you are familiar with the 3d process, try to get a starting model which will have the basic outline of the face, without all of the details. This starting model can be referenced from a photo, video, clay, drawing or even a stock 3d model. Face 3d modeling involves using the outline to build and modify the face so that it includes all the necessary details.
Often, the desired face is of an existing human, such as celebrity or political figure. When this is the case pictures or video can be used to aid in the creation of the basic shape and proportion of the face. Also these same picture or video can be analyzed to tweak the shapes and proportions of the face and to add the facial expressions. These facial expressions give any custom 3d model of the face a look that can be very realistic and almost as accurate as the existing human face. Then, the 3d modeler can use this realistic looking custom 3d model of the face and create stills or use it in animations, saving time and money during the 3d face modeling process.
For instance, as you go through the face 3d modeling process, you can expedite the process by capturing the human face using video. Then, you would use the location of the eye corners, nose tip and mouth corners together with specialized face recognition software to generate a highly realistic looking 3d face model. Then, you would use this output as the kick off point of your face 3d modeling and then you would add a range of poses, facial expressions and even additional features like audio and talking ability.
To achieve higher accuracy and a realistic human like appearance, you’ll need more facial points to go by and stronger equipment, which can become expensive. However, if you don’t have this available another cheaper way to realize a very human look is to manipulate the custom 3d models yourself or get 3d modeling and rendering services, like the services from Flat Pyramid, to do this for you so that you can have input on how the finished face 3d model will looks throughout your face 3d modeling until you get the required look that you need.
Modeling of the 3d hand models takes great attention to detail as the hands are one of the most complex body parts. The hands can dramatically change shape with each posture and can perform a wide range of complex movements in a short time.
3d models that are used for still renders tend to be less complex than the ones used in animations or for virtual worlds. The 3d hand models used for animations typically need a specific range of motion.
However, the ones used for virtual worlds are used to interact with the 3D world and a wide range of motion is needed. Also, a more personalized and realistic look is often desired. Therefore, different approaches should be used for modeling for still renders, animations, and virtual worlds.
Using proportions can give you less complex models that can be used for still renders and presentations. However, this approach may not be desirable when looking for very realistic and personalized human hands. See examples of stock 3d hand models.
The first approach is to use the proportions of the human body to size the hand. The length of the hand (from the wrist to the middle finger) should be roughly the length of the inner forearm. The male hands should be longer and wider than female hands. The hand of an adult male is about 189mm long and about 84mm wide, while the female hand is 172mm long and about 74mm wide. Also, the fingers should not be perfectly straight, instead they should have a tendency to curve slightly towards the middle finger.
The second approach is to use approximation to establish the right proportions. When using approximation techniques, the proportions are estimated using the existing features of the hand anatomy. For example, the creases of the palm, hand contours, and the wrinkles on the back of the finger knuckles typically mark the areas where the skin is attached to the tendon beneath the skin.
Other techniques involve generating a series of hand postures from real human hands, which yield hand movements and gestures that are very realistic. For this technique the hand 3d models are made up of both a dynamic and a surface model. The dynamic model is used to generate the hand postures. The surface model is based on 3D shape of a real human hand. This surface model is used to generate the hand shape based on the posture obtained from the dynamic model.
Motion capture and analysis is used to capture and process the hand movements. This can yield very realistic and accurate movements of the human hand. For example, for an animation of a hand making a fist, the 3d hand model fingers would need to curl in a spiral and not a circle. To achieve this, the movement of the joints of a real human (and their relative position in space) would be captured and recorded. Then this recorded movement would be assigned to the fingers so that they curl in a spiral making a fist.
Regardless of the approach you use, modeling of the human hand is complex and requires great attention to the shape, gestures, and movement of the hand.
As you all know the greatest entertainer ever – Michael Jackson suddenly passed away at the young age of 50 years in his rented home in Los Angeles.
While we were shocked like everyone else on hearing the news, we took it a little harder since we had actually been working on a custom 3D model job for Michael Jackson’s upcoming show in the UK, when we learnt that he had passed.
While the world mourns the passing of this legendary artist – Michael Jackson the “King of Pop” we here at Flat Pyramid pay tribute to him and his legacy by offering a Michael Jackson 3D model in his memory through one of our top 3D modeler – Yasmeen Jahan.
Even though we are in the 3D modeling business and not in the music industry and a 3d model artist is different from a musical artist, we are all still artists and share a similar passion for creativity. Here at Flat Pyramid 3D marketplace, our motto and goal is to allow artist Spend More Time Being Creative while we take care of promoting and distributing your 3D models and 3d products for you.
We encourage all you 3D artists that are good with character modeling to create all sorts of 3D Michael Jackson models in his memory. We will feature all of them in our newsletter, on our blog and send them to his people to use however they choose in his memory.
Regardless of what kind of artists (3D artist, Musical artist, 2D artist, etc) you are, and no matter where you are located in the world, we know that our work always out lives us so spend more time being creative. Like Michael Jackson’s art, your 3D models might live forever.
From one type of artist to another,
we all wish that Michael Jackson rest in peace.
3D modeling and animation of people and characters requires specialized skills and knowledge. Below find some tips that can help you create and/or get human 3d models that look realistic and have right human proportion.
3d character models require great attention to detail to achieve the right proportions, locomotion, and facial expressions that will allow the human model to convey human emotions, speech, and movement.
3D Modelers that specialize in 3d human models analyze human proportion to create an accurate representation of the figure and movement of the human body. They also take into consideration the color of human hair and skin. Human skin has a wide range of hues including very dark brown up to very pale pink. Human hair color is typically blond, brown, red, black, and gray.
3D Modeling of the Human Body
3d modeling the human body requires attention to detail to achieve the right proportion. The average height of an adult human is 1.5 to 1.8 m (5 to 6 feet) tall. To achieve a very realistic looking and accurate model of the human male or female, 3d modelers use heads instead of meters or inches as follows:
- The human figure is an average of 7 to 7 1/2 heads high(including the head).
- Width from shoulder to shoulder: 3 heads wide
- Distance from top of head to the bottom of chest: 2 heads
- Distance from wrist to the end of fingers of the hand: 1 head
- Distance from elbow to the end of fingers: 2 heads
- Distance from hip to the toes: 4 heads
- Length from top to bottom of buttocks: 1 head
Human body types vary substantially and depending on the type of human 3d model, these proportions are adjusted by the 3d modelers and refined by animators.
For example, ideal 3d female models with long legs and arms are typically 8 heads tall. Male hero 3d models have big chests and long legs and are typically 8 1/2 heads tall.
3D Modelers and Animators also analyze human movement in order to prepare the 3d human model for further processing including rigging and animation.
3D Face Models
3D face models of humans are animated using the lips, brows, and frown lines to create human expressions that convey certain emotions. The audio is synchronized with the mouth, eyes and brows.
To convey the right emotions, animators analyze the human body’s structures and movements. They also study facial expressions and human emotions.
The human emotions are typically captured and reproduced using the expressive face of a 3d model.
3d modeling the human faces also requires great attention to detail to achieve the right proportion.
Below are some typical proportions that 3d modelers use to create 3d face models. When the 3d face model needs to be attractive, special characteristics common to beautiful people should be used, see how to make 3d face models beautiful and attractive.
- The eyes are halfway between the top of the head and chin.
- The bottom of the nose is halfway between the eyes and chin.
- The mouth is halfway between the nose and chin.
- The corners of the mouth line up with the centers of the eyes.
- The top of ears line up above the eyes, on the eyebrows.
- The bottom of ears line up with the bottom of the nose.
- Eyes are typically centered halfway between the top of the head and the chin.
Before starting the process of 3D Modeling of the human body, keep in mind that it requires the expertise of highly qualified artists that specialize in this area. A good alternative is to buy high quality 3d human models in stock which also cut downs your 3d modeling costs.
When looking to use human anatomy 3d models to create visualization, animations, or still renders or images it is important to know what organs and textures are included with the 3d model. Below is a quick quide of what is included in a typical human anatomy 3d model.
3D models of the human anatomy are often comprised and grouped according to the human anatomical systems, such as the Digestive, Endocrine, Integumentary, Lymphatic, Immune, Musculoskeletal, Nervous, Reproductive, Respiratory, and Urinary systems.
A 3d modeler will create stock or custom 3d models of each of the organs that comprise each of the human anatomical system as follows;
3D Models of the Musculoskeletal system include all of the organs that enable the movement of the human skeleton and provide structural support and protection, including the bones, muscles, cartilage, ligaments, and tendons.
The Nervous system 3d models include the brain, spinal cord, and nerves as these organs support collecting, transferring and processing information with the brain.
The Respiratory system 3d models include the organs used for breathing, the pharynx, larynx, trachea, bronchi, lungs, and diaphragm.
The Urinary system includes 3d models of the kidneys, ureters, bladder and urethra, which are involved in fluid balance, electrolyte balance, and excretion of urine.
The 3d model of the Digestive system includes the major organs involved in the digestion and processing food and waste. Major digestive organs include the salivary glands, esophagus, stomach, liver, gallbladder, pancreas, intestines, rectum, and the anus.
The Endocrine system 3d model includes the hypothalamus, pituitary, pineal, thyroid, parathyroids, and adrenal glands. The Endocrine system enables communication within the body via hormones. Hormones are made by endocrine glands.
The skin, hair, and nails are part of the Integumentary system.
The Lymphatic system 3d models include all of the structures that are involved in the transfer of lymph between tissues and the blood stream. These structures include the lymph and the nodes and vessels that transport it.
The Reproductive system 3d model includes the major female reproductive organs, such as the ovaries, fallopian tubes, uterus, vagina, mammary glands. The male reproductive organs include the testes, vas deferens, seminal vesicles, prostate, and penis.
From the list of organs above one can see that a human anatomy 3d model will indeed include a lot of organ 3d models that will often be categorized in groups according to the human anatomical system.
Depending on the 3d model used, the organs can have several “layers” of details (macro or micro level) so it is always wise to check the 3d model specifications.
