There is a vast difference between 3D animation and traditional and 2D animation. The technical skills required for 3D animation are also different from those required for traditional or 2D animation.
In traditional animation, one is required to have drawing skillsand these are not really necessary to be a 3D animator. However, all of them require a good understanding of the principles of composition and movement.
3D animation is also called CGI or computer generated images. The frames of the animation are a series of images that have been generated using computers.It is possible to create extremely realistic objects and scenes by using 3D animation.
Here is how it works:
The frame rate is another factor that sets 3D animation apart. Traditional animations work on 2's and would need a new drawing every 2 frames. On the other hand, 3D animations are smooth always.
