What is 3D reconstruction?

3D Reconstruction is a method by which the object is re -created in a virtual, three -dimensional (3D) space using a computer. This can be done in a number of different ways, but usually includes the use of input data, such as two -dimensional (2D) photographs or scanning a real object. Once this 3D reconstruction is created, it can be manipulated or used in a number of different ways, including medical uses, reconstruction of law enforcement, and even creating 3D graphics for a movie or television. To this type of reconstruction there are two basic approaches that can be used, based on how the participants collect input data for reconstruction. Active reconstruction includes a form of interference between the reconstructed object and the sensor such as the scanning object or its photography. Passive 3D reconstruction, on the other hand, uses sensors that receive data without disturbing the object at all, such as a device used to receive light from distant stars.

This input data can then be used to create a 3D reconstruction of the original object or objects. For example, a human body scan can be used to create a 3D model of this person in the computer system. Similarly, passive scanning from distant stars can be used to create a 3D model away from the galaxy or to create an animated sequence showing the movement of different stars in the virtual space.

3D reconstruction medical use is relatively extensive, especially when used with a magnetic resonance (MRI) device that allows doctors to see the 3D brain model without performing surgery. These reconstructions are also used for a number of various reasons in the area of ​​law enforcement. 2D photos can be used to create a 3D model of a person to see what it can look like, and even the skull can be used to perform such reconstructions.

3D computer graphics for film and television can also use this type 3D reconsTrrucification to create more realistic pictures. For example, the scanning of the actor can be used to create a highly realistic 3D model of this actor, which is then used to create a digital stuker that can perform stunts that could be impossible for humans. Reconstruction is often used to create realistic 3D models of environments or objects, such as cars, to create pictures for ads that are more perfect than reality.
