Don’t be fooled by this seemingly simple question.
It was a very difficult topic and I felt tempted to not write it. You can answer it as complex or as brief as you like. It is important to communicate with clients how complex the process is but not to leave them confused. I will do my best to answer your question in a concise, but not complicated, manner.
Computer 3D animation is simply the creation of moving pictures in a three-dimensional digital environment. The 3D software allows us to manipulate objects (or 3D models) in order to create picture sequences that will appear as if they are moving.
Animation is where motion is simulated in such a way that the eye believes that there is actual motion. However, the illusion of motion is only due to the succession of images that are shown very quickly.
This theory is applicable to 3D, 2D and stop motion animations.
Traditional 2D animation uses hand-drawn pictures, with each one showing subtle differences from the last. It creates the illusion that motion is occurring when it’s played back in sequence. Stop motion animation uses real-life models that are slightly moved and filmed. The pictures will give the illusion of motion when they are played back. 3D animation is created within the computer. The computer can export the animation from the computer.
The three phases of 3D animation creation can be broken down into modeling, layout, animation, and rendering. This describes the final output of the computer graphics. This completes the 3D animation production process by combining the phases above with a few sub-phases.
There are many programs available for 3D animation creation. These software range from low-end to professional-level versions. Blender is a free 3D software that you can try if you’re curious about how it works. You can find the official website by simply searching for it.
