Visual Effects (VFX) have evolved tremendously since their introduction. Originally a simple technique, VFX has now become one of the most important aspects of modern entertainment, adding new dimensions and depth to films, video games and other digital media. In this article, we explore the long evolution of visual special effects (VFX), from the simple techniques of the early days of film to the advanced technology that amazes us in today’s digital age.
What are Visual Effects (VFX)?
Visual effect (VFX) is a term that refers to visual effects created or modified using computer technology in the production of films, video games, or other media. Refers to: These effects are intended to create elements that are impossible or difficult to achieve in the real world, such as explosions, digital monsters and fantasy landscapes.
But to fully understand the evolution of VFX, we need to look back at its history and see how the technique has changed as technology has advanced.
The Early Days of Visual Effects: Simple Practice
1. Practical Effects in the Era of Black and White Films
Initially, visual effects did not use digital technology at all. Instead, filmmakers create visual effects using a variety of practical techniques, known as practical effects. For example, various practical effects techniques such as image composition and the use of miniature models were introduced as early as 1902 in films by Georges Méliès A Trip to the Moon.
Today, visual effects rely heavily on manual skills and creativity, without the help of computers. Filmmakers use transparency to create multiple image compositions or to add an illusory background to a scene.
2. Use of Miniature Models and Screen Projections
In addition to practical effects, filmmakers also began using miniature models to create worlds larger than those that could be built in the real world. For example, in films King Kong (1933), miniature models are used to depict the giants and destruction of buildings. Although this technique was limited by the technical constraints of the time, it produced some extraordinary visual effects.
Technological Transformation: The Shift to Digital Effects
1. Developments in Computer Technology and CGI (Computer-Generated Imagery)
During the 1970s and 1980s, the advent of computer technology fundamentally changed the world of VFX. Film Tron 1982 was one of the first films to use fully computer-generated imagery (CGI) to create digital visual elements. CGI makes it possible to create objects and characters that were previously difficult or impossible to create with practical technology.
CGI now allows filmmakers to create worlds and characters using only computers. Film Star Wars: Episode IV: A New Hope (1977) is a classic example of the revolutionary use of visual effects at the time. Filmmakers like George Lucas and the team at Industrial Light & Magic (ILM) have taken VFX technology to the next level by using CGI to create fantastic space worlds.
2. Matte Painting and Blue/Green Screen Techniques
Furthermore, matte painting and blue/green screen techniques have developed rapidly. Matte painting allows you to digitally paint or create a background that cannot be created physically. This technique is often used in big films such as The Wizard of Oz (1939), creates a fantasy world with a digital backdrop.
In addition, the blue/green screen technique is very popular for separating objects and characters from the background and replacing them with a digital background using compositing techniques. With the introduction of increasingly sophisticated computer software, this technique has been further developed, allowing the achievement of more subtle and realistic effects.
The Digital Age: Impressive Innovation and Progress
1. The Emergence of 3D Effects and Virtual Reality
With the development of computer technology, the world of VFX has expanded with the emergence of 3D effects and virtual reality (VR). Film Terminator 2: Judgment Day 1991 was the first film to use CGI to create fully realistic digital characters, such as the T-1000, which was made of liquid metal.
Advances in computer technology have made 3D effects increasingly common in a wide variety of films, allowing filmmakers to create worlds and objects that appear real. One of the highlights is the film Avatar (2009), which uses advanced 3D technology to make the visual experience far more intense and immersive.
2. Advances in Particle Rendering and Simulation
In addition, rendering capabilities are also growing rapidly. The rendering process is the phase where the final image is created and enhanced with VFX. Thanks to advances in computer hardware and software, the rendering process has become faster and more realistic.
More advanced particle simulations to create effects such as smoke, fire, rain and explosions. This type of technology makes animations more dynamic and real. Movies like The Avengers And Transformers uses particle effects to create huge explosions, epic battles, and stunning natural scenes.
VFX in the Modern Entertainment Industry: Film, Games and TV
1. Influence of VFX in Blockbuster Films
In today’s modern era, almost every blockbuster film uses VFX technology to improve its visual quality. For example, the Marvel Cinematic Universe (MCU) uses VFX to create stunning visual effects with massive battles and elaborate special effects in films such as Avengers: Endgame. Without visual effects (VFX), many of these spectacular scenes would be difficult to achieve.
2. The Role of VFX in Video Games and Mobile Applications
Apart from films, VFX has also revolutionized the gaming industry. Modern games like The Witcher 3, Red Dead Redemption 2, dan Cyberpunk 2077 uses VFX technology to create a highly detailed and realistic world. Video game visual effects create a more immersive gaming experience with dynamic weather, huge explosions, and an exciting open world.
The Future of Visual Effects: Towards a More Advanced Technology
1. Artificial Intelligence and Machine Learning in VFX
Advancements in artificial intelligence (AI) ushered in a new chapter for the VFX industry. AI and machine learning are now being used to speed up production processes, improve image quality, and even automatically create more realistic animations. AI is also used to analyze images and create smoother visual effects.
2. VFX and Immersive Experiences with VR/AR
In the future, we will see more and more use of VFX in virtual reality (VR) and augmented reality (AR). The use of VFX in VR and AR offers a more immersive and interactive entertainment experience, allowing users to experience visual effects in a completely digital world.
Conclusion
From simple techniques in the early days of filmmaking to today’s advanced technology, visual effects (VFX) have developed rapidly and made extraordinary progress. Advances in computer technology, CGI, 3D effects, and artificial intelligence have changed the way entertainment is produced and enjoyed. With the rapid development of technology, VFX will continue to shape the world of entertainment, providing audiences and players with new, more realistic and intense experiences.
FAQ
1. What is meant by visual effects (VFX)?
VFX is a technique used to create visual effects through computer devices in the production of films, games or other digital media, which allows the creation of visual elements that would not be possible in the real world.
2. What is the difference between practical effects and VFX?
Practical effects are visual effects that are physically created, such as miniature models or the use of pyrotechnics for explosions. While VFX involves the use of computer technology to create or modify visual effects.
3. How has CGI technology changed the world of cinema?
CGI allows the creation of completely digital characters and worlds from computers, changing the way filmmakers create fantasy worlds and more realistic visual effects.
4. What is motion capture (MoCap) in VFX?
Motion capture is a technique that captures an actor’s physical movements to transfer them to a digital character in a film or game, creating more natural and realistic movements.
5. What can we expect from VFX in the future?
In the future, we can expect more use of artificial intelligence (AI), machine learning, as well as integration with VR and AR technologies to create more immersive and interactive entertainment experiences.
