Description: The representation of three-dimensional images, including depth, allows for a more realistic and detailed visualization of objects and scenes. Three-dimensional (3D) images are created by combining modeling, texturing, and rendering techniques, simulating human visual perception. Unlike two-dimensional images, which only represent height and width, 3D images add a third dimension: depth. This is achieved through different methods, such as stereoscopy, which uses two slightly different images to create an illusion of depth, or through computer graphics that generate three-dimensional models from mathematical data. 3D images are fundamental in various fields, from animation and video games to medical simulation and architectural visualization, providing an immersive and detailed experience that enhances understanding and interaction with visual content.
History: The concept of three-dimensional images dates back to stereoscopy experiments in the 19th century, where two images were used to create an illusion of depth. However, the development of computer graphics in the 1960s marked a significant milestone in the creation of 3D images. In 1972, Edwin Catmull and others developed the first animated 3D model, leading to the creation of computer-animated films in the 1990s, such as Pixar’s ‘Toy Story’ in 1995, which was the first fully computer-generated film.
Uses: Three-dimensional images are used in a variety of fields, including medicine, where they are employed to create accurate anatomical models that assist in surgical planning. In architecture, they allow for the visualization of projects before construction, facilitating decision-making. In entertainment, they are essential for creating video games and animated films, providing immersive experiences. Additionally, they are used in education to illustrate complex concepts in science and mathematics.
Examples: An example of the use of 3D images is the visualization of magnetic resonance imaging in medicine, where doctors can observe internal body structures in three dimensions. In the realm of video games, titles like ‘The Legend of Zelda: Breath of the Wild’ use 3D graphics to create an interactive open world. In architecture, programs like AutoCAD and others allow architects to design and present 3D models of buildings and urban spaces.
