The Evolution of Animation Technology: Perspectives for CG and AI Video Production

Computer Technology and the Evolution of Modern Animation

The first part covered the birth of animation and the development of cel animation. In this second part, we take a closer look at the revolution brought about by computer technology and the evolution of modern animation.

The Arrival of Computer Animation

Computer technology began entering animation production during the 1970s and 1980s. This made production more efficient and expanded the range of expression compared with traditional hand-drawn animation. Pixar's 1986 short Luxo Jr., in particular, was highly acclaimed as the first fully computer-generated animated work, demonstrating the potential of computer animation.

The Spread and Development of CG Animation

In 1995, Pixar released Toy Story, which achieved worldwide success as the first fully computer-generated animated feature film. Its success rapidly brought CG animation into the mainstream, leading to a succession of innovative productions. Studios such as Disney and DreamWorks also committed to CG animation, ushering in a new era of animated films.

The Digital Transition in Japanese Animation

In Japan, animation production also became increasingly digital during the 2000s. Digital painting and CG replaced traditional cels, improving production efficiency and quality. Productions using CG became more common, and works such as the Evangelion series and Knights of Sidonia attracted attention for fresh visual approaches that made extensive use of digital technology.

The Internet and the Evolution of Animation

The spread of the internet also transformed how people watch animation. Streaming services such as Netflix and Amazon Prime Video invested in animation distribution, allowing viewers to enjoy high-quality animated works from anywhere in the world. Production environments have also diversified, with independent animation projects being funded through crowdfunding, for example.

The Diversity and Future of Modern Animation

Technological advances continue to broaden animation's expressive range. Techniques such as 2D animation, 3D animation, and stop motion are being combined to produce a succession of distinctive and diverse works. In the future, animation using more advanced AI technology, VR, and AR is expected to offer viewers new experiences.

Conclusion

From its beginnings to the present, animation has evolved alongside technological innovation. The introduction of computer technology expanded its expressive range, and it remains a central part of entertainment today. Animation will undoubtedly continue evolving with further technological advances, bringing us new visual experiences.
