3D or three dimensional models are used for a variety of purposes. Surgeons and filmmakers are only two of the many professions that use 3D models on a regular basis. 3D models are created by mapping various coordinates in a 3D space.
Medical professionals use detailed 3D models of organs to teach medical students, outline and plan surgical intervention as well as demonstrate procedures to students and patients. Plastic surgeons use detailed software to create 3D models of the body to demonstrate a “before and after” to the potential patient.
There are two types of 3D models: Solid and Shell. Solid models define the volume of the 3D model are solid, such as piece of stone. Solid 3D models may be used in many engineering models. They are used for simulations that are non-visual. Shell 3D models are more diverse and contain the outer layer, and represent the surface of a 3D model. Shell 3D models are used within filmmaking and video game creation to allow the user to manipulate the model as needed.
3D models have many benefits over traditional 2D models, such as: the flexibility that is offered with the use of 3D models – we can change angles, or create animated imaged much quicker than using two dimensional models. 3D models combined with software enable us to make instant calculations. This is one of the reasons why 3D models are increasing in popularity with earth scientists and engineers. Lastly, 3D models allow us to have a concise picture of an object which allows for higher levels of accuracy when building, designing or figuring. Additionally, 3D models have the benefit of becoming easily animated to see all facets of a structure or object. It is this feature, the ability of 3D models to be turned on a sphere, from the middle point that has increased the functionality of the renderings.
3D Model use in Graphic Design
3D models are used widely in graphic designs that contain 3D animations. A graphic is created by a coordination of points on a chart. A model does not become a graphic until it has been visually displayed by animation and rendering.
There are three parts to creating a 3D model within a graphic design. First, 3D modeling occurs in which a shape is given to an object using the coordination points. These points are graphed onto a chart. In the case of graphic designs, the majority of models will be shell models which can be easily manipulated for size and shape.
Next, layout and animations occur which give can give movement to the object within its scene. Next comes the process of rendering, rendering the 3D object refers to creation of images from that particular object. This particular step gives the spacing between the image and the scene in which it is found it with by special measurements. Layout determines how the object is going to move over time, and if any change will occur within the object.
Rendering is the process in which the animation is taken from a 3d model to a graphic. It includes the visualization of an image that can be manipulated with style or light. Rendering has two basic processes: these are, scattering and transport. Scattering defines how the surface of the object will interact with the light and transport defines the process of how light will get to one place or another.
There are two ways that a 3D image can be implemented into a software program. It can be created by the program, or another design program, or the image can be scanned into the computer with scanning software.
After a model has been rendered, it is easily transformed to 2D to ease the editing process, but the process of creating a 3D model from a 2D means the three step creation process must occur; (modeling, layout and rendering).
3D Model Use in the Medical Field
More than likely, the most familiar 3D models in the medical field can be seen on a visit to the local Doctor’s office. Within that office there are 3D structures of organs, from the heart and lungs to the digestive or skeletal system. These models are used for teaching anatomy or medical students, or used to demonstrate abnormality, disease or procedures to patients. Although the organs lie inside the body, the 3D models give the patient an opportunity to visualize the organ in the correct manner.
Software has made it possible for surgeons to create surgical plans, and be assisted throughout the procedure. Specific software renders 3D images of the organs that are to be operated upon.
These medical 3D models are accurate in size and shape but some also in detail – even texture. The models are created as similar to organs as possible. This feature allows surgeons to learn, before assisting with a procedure on a human body, to know the feel of an organ. Specific textures and materials are used to create 3D heart models, as the heart is certainly not made from hard plastic.
Some specialists, such as plastic surgeons render 3D models to allow the patient to visualize the results of specific surgeries. In this process, a picture is taken of the patient, or, a personalized 3D model is created through the use of software based on specific measurements and coordinates to create the desired changes, and visualize these changes – instantly!
3D models have become valuable teaching tools. Many websites allow the user the opportunity to gain valuable insight into the inner working of organ through 3D models. These models are beneficial to students in a secondary school level, all the way to students in a Medical Doctor program. The accuracy is pristine and the renderings allow familiarity, and are easier to learn than a two dimensional image on a page.

How to Smooth the Edges of a Polygon Model
Polygon models which have surfaces that appear curves are actually created with tiny series of lines. These lines can be smoothed in the rendering process making the lines appear smoothed, and authentic. Many created 3D models are created from these series of tiny lines, but have the appearance of curved surfaces such as furniture, or vehicle 3D models.
Sharp angles and corners are the targets of these tools to create a lifelike image. In the making of a 3D model there are three main types of smoothing that can occur in the making of a 3D model; forced smoothing, super forced smoothing and beveled smoothing.
An image can be smoothed to the user’s satisfaction – but trial and error is the best way to determine when an image has received enough tweaking and smoothing. Over smoothing occurs within many novice 3D modelers, and can be avoided with practice. Many tutorials are available on the internet for modelers to take advantage of.
Forced smoothing includes the smoothing of the vertices. To get this smooth grouping on the surface of the mesh, vertices must be split away from the parent polygon creating the image of the smoothed surface. Over smoothing can lead to edges looking “too soft” or “mushy”.
Forced super smoothing consists of a smoothing process that removes the additional polygons from the mesh, separating them from the parent polygons. Forced super smoothing of a 3D model allows the user to move the polygons a fraction to create a smoothing effect on the 3D models.
Beveled Smoothing adds extra polygons to the 3D model to create the smoothing effect on the shell of the 3D model. This insertion of polygons creates extra space for light to be distributed over the 3D model and allow for shadows and shading occurring. These extra faces of the polygons create detail, creating a smoothed and lifelike 3D model.
How to Profit from 3D Model Creation
A single 3D model can demand thousands of dollars in profit when sold to graphics or design companies. For a 3D model to command such a high price it must be highly accurate and lifelike.
Creating polygonal models has shown to be more profitable than creating other types of 3D models such as b-spline or NURBs 3D models. This being said, many buyers of 3D models take into account that NURBs models can be transitioned into polygonal models, but it is not possible to create a NURB model from a polygonal 3D model.
There are high market values for models that are lifelike – whether they are human models, organ models or models of household items or furniture. These 3D models are necessary within video games and other animations.
These lifelike models can take extensive periods of time to complete and therefore it is important to focus on specific aspects of the model. For example, when making a model of a popular vehicle, create the exterior of the vehicle first, but overlook parts of the vehicle that are not going to be required – such as the engine, or trunk.
In order for the artist to reach high earnings levels they must have an eye for detail and the know-how, and skill to create these highly specialized 3D models. Detail and versatility are the keys to selling designs in the 3D model business. When companies purchase models for thousands of dollars, they expect the models to transition into different formats with ease. Creating models that can transition easily yields more income than a static 3D model.
For these reasons, details such as texture should be avoided as many companies employ individuals that can add on this texture. As well, when an artist adds texture to a 3D model it can make the model hard to transition into other forms.
