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 save time if you download a stock 3d model for your face 3d modeling and animation. Using this ready made 3d model can help you during your face 3d modeling process. However, keep in mind that when you utilize one that has that is already made you will more than likely have to modify it so that it can be ultimately look real and unique.
To start, lets look at the convenience of using this approach to start this highly specialized process. Custom 3d models allow for an easier way to get the right proportions for the 3d face model and also everything else that is needed to get what you need from your face 3d modeling project or for your clients.
Custom 3d models give an easier way to obtain the right proportions for the 3d face and also the level of quality and detail that are needed to satisfy the need.There are many advantages to using a custom 3d model to start the process including getting realistic location of the eyes, eyebrows, face, mouth and other proportions.
For instance, for a unique character, it is very likely that a custom 3d models is needed. Otherwise one that is already made that is also highly realistic and can even include facial movements can meet the need.
Keep in mind that to use this 3d face model character or change anything on it, you will need specialized rendering and 3d modeling skills in the course of the face 3d modeling in order for you to simply mesh it again, built it altogether or even display it so that it can be seen like a human face. The point is that regardless whether you start off with a stock or a custom 3d model, the reality is that a stock 3d model is not exclusive so you need to change it to suit your needs or the need to have an original face that nobody else is using in their projects.
In addition, most face 3d modeling nearly always involves further manipulation, particularly adding facial movements and emotions that bring any face or character to life. Put simply, you may often find that most custom 3d models of the human body need lots of the features that will be discussed below including; an accurate but lightweight version with very few polygons, human emotions, rigging, formats for game engines and virtual worlds, scene setup, post production processing, etc.
There are many techniques you can use to build custom 3d models of human faces. The 3d model can be referenced from a photo, video, clay, drawing or even a stock 3d model. Face 3d modeling involves using the points are used to create and customized to incorporate all of the facial details. Nowadays facial movements and expressions are mapped in connection with the structure and position of the eyes, nose, lips and eyebrows.
Facial expressions are achieved with the movements of the face muscles, such as the movement of the cheeks, nostrils, eyelids, upper and lower lips and also with small changes in the creases and wrinkles of the human face. These details that are added by the 3d modeler as visual cues are what convert a lifeless face into a human like face. Then, the 3d artist can use this custom 3d model and distill it to effectively create a look that is very realistic, saving time and money during the 3d face modeling process.
For instance in the face 3d modeling process, we discussed above that one can use reference videos or photos. It is important to note that these references that are used to pinpoint the location of the eye corners, nose tip and mouth corners are obtain by using specialized face recognition software. The output of the face recognition software is used as the kick off point of the face 3d modeling, so then you can add a range of poses, facial expressions and speaking.
However, to achieve this level of accuracy and ultimately a realistic a human-like appearance, you will need to use these specialized face recognition software to obtain the amount of facial points to go by and this can become costly. Often this high end capture devices and respective software are not available and can’t be purchased due to their cost. Therefore, another cheaper way to achieve a very human look is to manipulate the custom face 3d modeling until you achieve what your client specifically needs, without the added expense and overhead of getting capturing devices or specialized software.
