The difference between 2D and also 3D animation

We can all tell the difference in between watching a 2D man movie (such as Aladdin or the little Mermaid) and also a 3D man movie (such together Toy Story or Minions). Most the us recognize that 3D computer animation is done on a computer, yet what is 3D computer animation REALLY?

In this video

I’ll explain the main point differences between the process of 3D and also 2D animation. I’ll cover worries like frame rates, relocating holds, functioning on a 3D software and more.

What walk it mean to make a 2D animation as opposed to make a 3D one? well, in reality the making process is really different.

For starters, come animate in 2D you need to be able to draw. Everything you check out in classic 2D computer animation had to it is in drawn. Usually framework by frame.

for a 3D animator, while gift able to draw well is defiantly one advantage, the is not mandatory. Once you’re animating in a 3D setting you relocate the character, kinda favor a puppet, right there on the computer.

Lets go into details:

In 2D animation, you attract the very first key pose, and also then the remainder of the vital poses. Girlfriend then draw every the frames in between them. Yet when we attract the character, we only attract what is seen in the shot. When a character’s eight is behind their back, we don’t draw that arm. If miscellaneous is not shown, i don’t have to draw it. If a character closes their eyes, the eyeball does no exist anymore until I attract it again.

This concept is one of the very first big differences between the two species of animation. That’s due to the fact that when you’re working in a 3D environment, every the parts of the personality are always there. And also you have to be mindful of them, if in 2D girlfriend just draw whatever is seen and the remainder does no exist.

This ide gives a tiny advantage come 3D animation, due to the fact that since the personality is in a 3D space, you can readjust the camera after you animated the scene. In 2D, if you change the shot angle you will have to redraw the whole sequence, because you drew the personality from a particular angle. When you animated in 3D you’re quiet considering the camera angle at all times, but its much much easier to later readjust it if you require to.

Animating in 3D

Ok, so us all know that animating in 2D way drawing a lot. However what does it mean to animate in 3D? just how does that look like? well, lets see.

In our scene, we will have actually a 3D model. The model is rigged, which means it is programed with all the appropriate virtual bones and also controls to do it as easy for animators as feasible to animate.

As you deserve to see, this model has actually controls in every crucial position in the body. I have the right to grab one of the controls and move the around. But that only describe how we can move the model, no actually animate.

There it gets a bit an ext complex. Watch at this window. This is called a graph editor.


3D computer animation is all about graphs and curves. Yeah, I understand math and formulas don’t belong in an imaginative thing like animation, yet there it is. Now, you can be a bit overwhelm when I display you this, yet these curve correlate to each controller. There’re actually multiple curves that correlate with each one controller, due to the fact that we’re moving in a 3 axis system. So yeah, one animator security a many time looking at graphs and curves.

It’s in reality a lot easier than the reads here, when you begin playing through it. We also have an entire course called Maya computer animation which teaches you whatever you require to know to be able to animate in 3D favor a pro.

Now us know about curves, yet we still didn’t covering the computer animation process.

Lets to speak we want this personality to raise their hand. We’ll walk to the very first frame in the timeline and create a keyframe. A vital frame is you telling the regime you desire the hand to it is in in a certain position at a certain time. Then we’ll go 10 frames forward while line and also move the hand up. The computer then interpolates the difference in between the very first and second keyframes we made and also generates the movement.

An animator will repeat this procedure for almost every body parts for every keyframe, and tweak them because that hours and hours. After ~ a many animating, the graph editor would look like in the photo above. This editor is what animators look at most of the time, as with 2D animators look in ~ their drawings.

Frame rate

Another difference in between 2D and also 3D animation is the structure rate, and also what wake up on moving holds. What do I average by that? Well, in film we usually occupational with 24 frames every second. In 2D animation That means that there is a drawing every frame, 24 times a second. That’s a lot, yet when there’s no large fast movement we can frequently settle for 1 illustration lasting because that 2 frames. For this reason there’re actually 12 illustrations per second. This is dubbed “working ~ above 2’s”, due to the fact that you’re do a change, or a new drawing, every 2 frames.

When the activity is really still, we might also work on 3’s and also 4’s. You see that a lot in Japanese animation and stop motion. At some time they would hold the same illustrations for many frames.

In 3D though, it doesn’t really job-related like that. When a 3D character doesn’t move at all, even for 1 frame, the seams wrong. It appears dead. This provides it challenging to execute a “moving hold” in 3D animation. A moving host is provided whenever you require a character to do nothing, however still feel prefer their alive.

While in 2D and stop activity you deserve to settle because that a drawing every 3-5 frames, or even not have it move at all for a couple of seconds, in 3D we constantly have to keep the character moving.
