How to make 3D models based on 2D Images?
Converting 2D images to 3D models refers to the process of transforming flat 2D images into virtual 3D objects that can be viewed and manipulated in a 3D environment. There are several methods for achieving this conversion, including photogrammetry, structured light scanning, and manual modeling. Photogrammetry is a technique that uses multiple images of an object taken from different angles to create a 3D model. The software then matches corresponding features in the images and calculates their positions in 3D space to create a 3D model. Structured light scanning is a similar process that projects a pattern of light onto the object and captures the deformation of the pattern caused by the object's surface geometry. This information is used to calculate the object's 3D shape. Manual modeling involves creating a 3D model from scratch, either by sculpting in 3D modeling software or by using 3D scanning to capture the object's shape. This method requires more manual labor, but provides greater control over the final result. Converting 2D images to 3D models can be useful in various fields, such as architecture, product design, and gaming. It allows designers and engineers to visualize their designs in a more interactive and immersive way, and to test their products in a virtual environment before moving to physical production.
