What is 3D animation?

Avatar SEOadmin | January 4, 2020

3D animation is the art of using motion to bring characters, vehicles, props, and more to life within TV shows, films, and games.

3D Artists are often involved in several early steps of the VFX pipeline in order to ensure they deliver an animation-ready model. For example, in order to give a character the right personality traits and movements, the Animator needs to make sure that whoever is rigging the model does it with those things in mind. During the rigging process, the character is given bones, skin weights, and constraints that allow it to move in specific ways. If this is not done with the Animator’s needs in mind, the model will be sent back.

Animators are responsible for giving objects weight and timing that result in the object feeling like it truly exists in the world we see it in. A great example of this would be baby Groot from Guardians of the Galaxy vol. 2. Though this movie takes place in a fantasy world, Groot’s body movements and facial expressions are so fluid and realistic, they cause viewers to laugh and feel sentimental. He truly fits seamlessly into the world around him. Animation is a huge part of bringing characters to this point.

A day in the life of a 3D animator

The daily responsibilities of an animator vary depending on the type of job you are working on. As with every other step in the pipeline, once you receive your assignment, research is key. For example, Disney artists working on the film Zootopia spent time at animal wildlife reserves studying the behavior and movements of the animals in person. Following research, the artist then decides what techniques to use and starts blocking out the main poses of the object they’re working on. Techniques include things like placing keyframes and choosing between IK and FK, which are different ways to have the bones move when animating. Main poses will include the starting pose, ending pose, and some poses in between. Once these poses are in place, the artist gets feedback from a supervisor and moves forward with perfecting the movements of their model.

An animator’s responsibilities vary due to company size. Smaller companies may be more likely to hire artists that also have the ability to rig models. The company saves time and money by having one person do both tasks. A larger company may hire specialized artists who focus on one specific task so that when more high profile projects come through, they are handled as efficiently as possible.

How to become a 3D Animator

Practice makes perfect. When you are first learning, it takes some time to get your animations as smooth and precise as you would like. Repetition will eventually make the tedious aspects quick and natural, which will then let you focus on the more in-depth nuances and personality of your animations.

As mentioned before, research is key. Prepare yourself for a career in this field by spending time gaining knowledge of:

  • The motion of humans, bipedal creatures, quadruped creatures, and animals
  • Facial movement and portraying different moods
  • Mechanical design
  • Mechanical operations
  • Weight and physics

As technology improves, artists are expected to understand how motion capture works. Once the motion capture data is imported, animators will often have to tweak the keyframes to perfect the facial and body movements of the character.

One recent example of the successful use of motion capture tools is the War of the Planet of the Apes. The actors who played the apes wore motion-capture suits, which were filmed by a series of cameras. The data was then sent to animators who made creative choices to enhance the personalities of the 3D modeled apes that would replace the actors. This process is becoming more commonplace by the day in both the film and games industries.
