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.
