Making a realistic and lifelike human character is one of the hardest tasks in 3D graphics. For a long time it was known as the “Holy Grailâ€� among 3D artists in the community. The reason why this skill is so desired, is the possibilities it gives you in the movie or advertising industries. Imagine you could create fully artificial digital actors and make the audience believe they are real. So real that there would be no questioning it. We are all familiar with the best examples out there – Gollum in the Lord of the Rings Trilogy, Davy Jones in the Pirates of the Caribbean or the alien species in Avatar.
There are a vast amount of techniques and tools developed to aid this process. Geometry composed of millions of polygons can be easily molded like clay to form the shape of a character. The 3D model then is linked to skeletal systems that enable artists to animate the body. Complex rendering algorithms calculate how light spreads in the scene to simulate physically accurate shadows and illumination. Shading procedures are then used to compute how textures react when light hits the surface. Rendering engines imitate details of human skin to such an extent that even the scattering of the light under the skin is taken into account.
Above all that, the artist has to convey the personality and make the audience believe that it is a real person. That’s why some 3D characters look so strange – technically all the skin and shading details are correct, but something is lacking in the character. Sometimes the expression is unnatural, or the traits of the face are too perfect. When 3D characters look “almost â€� like actual human beings, it can cause repulsive thoughts, the experience often colloquially said as the uncanny valley.
Anyway, new software and ever growing computing power enables artists to create computer generated characters you would never guess it is not a real photo. Here are 40 of the most interesting and photorealistic 3D characters in the community to date.

All For Now
3D technology is evolving so fast that soon digital actors maybe replacing the real ones before too long. When it will be? Only time will tell. Tell us, how many of the images above could you not tell apart from a photo?
