Do you want to master the best 3D Animation Techniques? Moving objects that seem in three dimensions are a part of 3D animation. Artists may manipulate and spin 3D figures like real objects, in contrast to 2D representations. But did you know that there are also many 3D formats and production methods?
Continue reading to learn about the many styles of 3D animation and how they vary from one another.
Types of 3D Animation
Three-dimensional animation has advanced significantly since its inception. As technology advances, numerous sorts and 3D Animation Techniques follow. Its goal, regardless of the many approaches used, is to provide the audience with a genuine reality. Continue reading to learn more about the three popular 3D animation types used today.
3D Video and Film
The most popular form of 3D animation is a 3D video and film. It is a 3D visual aspect of moving pictures in the digital sphere. A 3D experience has a third dimension and more depth. In other words, it provides a more accurate visual representation of how we see things in the real world. To view this style of video, special 3D eyewear is typically needed.
This kind moves the subjects around a 3D environment using motion graphics. In contrast to other genres, 3D videos and movies are simply visual, necessitating no user input. It is also known as passive 3D animation for this reason.

Interactive 3D
This 3D animation was produced using 3D computer software and is entirely digital in nature. While the visual experience is important in 3D video and film animation, this type requires user participation. This enables users to travel through the 3D world on a computer screen while in first- or third-person perspectives, using a mouse and keyboard as external controllers.
Real-time rendering is the name of the technology that powers all of these experiences.
In a conventional 3D animation, the video you are watching is composed of a number of static images that have been computer-rendered. The process of rendering involves turning a 3D model into a 2D picture.
Rendering a full video can frequently take a computer, or a group of computers, days, weeks, or even months. To make matters even more challenging, the entire piece must be re-rendered if an artist wants to make even the smallest alteration.

Virtual Reality 3D
Virtual reality (VR) animation is the sort of 3D animation that has given users the most access to completely new experiences. This also uses purely digital space produced by 3D computer software, similar to interactive 3D. VR is used and enjoyed in a more immersive manner, though. This type needs a gadget, like Google Glass or Oculus, to let people interact with the real world.
Virtual reality 3D animation is the most immersive and difficult to make of the different styles of 3D animation.
The following are the three primary VR categories:
- Non-Immersive Virtual Reality: Non-immersive VR technology creates a virtual world on a computer, but the user is still aware of and in control of their physical surroundings. A good example of non-immersive VR in video gaming.
- Semi-Immersive Virtual Reality: This kind of VR offers an experience that is partially based in a virtual setting. When combined with graphics computing and big projector systems, such as flight simulators for aspiring pilots, this kind of VR makes sense for instruction and training.
- Fully Immersive Virtual Reality: At the moment, fully immersive VR technologies are not yet available, but because of how quickly technology is developing, they might be. With this kind of VR, the simulation experiences are the most lifelike in terms of sight, sound, and occasionally even smell. Games that simulate racing in a car are an example of immersive virtual reality since they give the player a sense of speed and dexterity. VR is increasingly being used in fields outside of entertainment and games.
Types of 3D Animation Techniques
3D animation has since advanced significantly over time. Since then, other 3D Animation Techniques have been developed for 3D animation with the purpose of expanding the possibilities.
Inverse Kinematics
This method, which is also known as rigging, entails animating a 3D figure with just a few controls such that it behaves and looks like the skeleton or structure of a puppet. According to anatomical regulations, each bone is connected to the one before it in such a way that when one bone moves, all the vertices that are connected to it also move.
Only having to adjust the position and rotation of the bones instead of all of the model’s vertices, drastically streamlines the animator’s job. In the end, the bones’ movements are used to determine the movements of the vertices. The surface representation of the model is referred to as a mesh or skin, while the skeleton itself is referred to as a rig.

Fluid Simulation
Finding a set of joint configurations that would move the provided points with the softest, quickest, and most precise motion is the main goal of this animation technique. It is applied to models of any characters or objects that are built using skeletal animation and is most frequently utilized to determine how the arms and legs of figures should move.
The last bone in the chain is moved to create movement, and the remaining bones in the chain move into place on their own. For instance, the wrist will automatically move in the desired direction if the grip on the object with the fingers is dynamic.
This is how it differs from forwarding kinematics: in its case, to move the character’s hand to the object and take it, one must first move the shoulder to give it a general position, then set the position for the forearm, and finally turn the hand in the appropriate direction to make sure the object is captured with fingers.
3D Skeletal Animation
In this technique, the digital sculpture’s skin, or mesh, and the supporting structure, or rig, or skeleton, are laid out before animating the object or character. Complex objects and human-like animations are frequently created using this technique.
The technique’s aim is obvious from the name: animated fluids like water, lava, or smoke. The key is to mimic fluid motion as closely as possible, which enables the creation of stunning images of thunderstorms and storms. If it is necessary to depict the behavior of fire or significant atmospheric effects, the same technique is employed.
As a result, it is used frequently in movies, ads, and even video games.
Conclusion
You are now aware of the most well-known forms of 3D Animation Techniques and their applications. The frontiers of realism are being pushed by 3D animation as it continues to permeate the most varied aspects of our lives. You can try your hand at the applications we’ve mentioned if you’re thinking about those as choices for making your animation.
