CGI, or Computer-Generated Imagery, is a technology that simulates images using computers. It is a technology that helps create visual elements that can be both static and dynamic, such as 3D character animations, environments, and other visual effects, through computer software. The technical methods have advanced to the extent that CGI is now virtually ubiquitous across various platforms.
Notably, CGI is widely used in the production of anime. Anime CGI refers to scenes that utilize computer-generated imagery to create characters, backgrounds, and transitions between them.
In practice, there are numerous advantages to choosing CGI over traditional animation. CGI is often regarded as a superior technology, particularly in terms of the cost of production. This is because it simplifies the process of creating complex models or elaborate character designs that would be labor-intensive in traditional animation.
Therefore, using CGI is a way to streamline the animation process (keeping in mind that it still requires artistic input, especially in today’s digital age). However, not everyone fully recognizes this method’s advantages. Some critiques focus on the fact that certain aspects of CGI-animated scenes in anime can detract from the overall experience.

Of course, 3DCG (three-dimensional computer-generated animation) often faces the most scrutiny. Generally speaking, 3DCG is utilized in ways that viewers may not even notice, especially in fast-paced action scenes, such as during battles. Instead of creating multiple frames with changes in the background, the focus can simply be on creating a 3D environment that allows for continuous action while directing attention to the movement of characters within that scene.
Despite some shortcomings that might leave viewers feeling unsatisfied, there are still remarkable 3DCG works that exceed expectations, such as Beastars, Houseki no Kuni, and Trigun Stampede. Unfortunately, the style of this animation often leads to more failures than successes. This is partly because 3DCG animation tends to evoke mixed feelings among audiences, who may find it awkward or visually jarring.
Some comments from netizens regarding this film:
– Wow, is this a 3D animated film? I can’t believe it!
– Amazing!
– Is this the right way to use 3D in anime? Fantastic!
– The quality of the final product is surprisingly high, much better than many works that cost millions of dollars today.
– I’m impressed because this film makes many people unaware that there is 3D animation in it. I always thought that using 3D correctly means it can be combined with 2D.
– More than ever, I hope they will remake Ranma 1/2!
