By Mike Turner

When you need to get face 3d modeling that is highly realistic and particular to want you or your clients want, it is a good idea to check out custom 3d models. Also, if you need to portray human emotions or will require further manipulation, then it is best to use the services of expert 3d modeling and rendering artists for the face 3d modeling. Aside from using custom 3d models, you can include features such as particular emotions, expressions, hair, eyebrow movement and particular features, especially birth marks that make the face look real.

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, if you want exclusive licensing rights for the face to use it for a character, you will probably need custom 3d models. Or you can get practical and get a quality one that is already made and may even include rigging or facial movements.

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 almost always involves further processing particularly when adding facial expressions such as happiness, anger, sadness, thoughtfulness, shyness, etc. In other words, you will regularly find that most custom 3d models of the body need some or lots of additional manipulation to meet your clients needs including; accurate facial expressions, body motions, rigging, low polygon version for game engines and virtual worlds, scene setup, post production like adding the audio and so on.

There are many techniques you may use to create custom 3d models of human faces. To initiate this process quickly, try to get a starting model that will have the basic outline of the human shape, without all of the details. The referenced 3d model can be referenced from a photograph, video, or even a stock 3d model. Face 3d modeling involves using these already referenced points and then using them to build and customize it to include all the necessary details.

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, one can use reference videos or photos. Then, you would use the placement of the eye corners, nose tip and mouth corners and 3d modeling software for face mapping and recognition to generate a highly realistic looking face 3d model. Then, you would use this output as the starting point of your face 3d modeling and then you would add the many poses, facial expressions and speaking. More facial dots or references translate to more accuracy.

Therefore, to realize that highly realistic look for any part of the human body, especially the face, it is best to get face 3d modeling services to manipulate custom 3d models until the face achieves the desired look.
