The classification of technologies is a systematic approach to organizing information, and the discussion of applications reflects current industry practices.
Think critically
How might the advancements in AI and machine learning further blur the lines between image-based and scanner-based 3D reconstruction, and what new opportunities or challenges might this present for design practice?
Design Principles
"Select the 3D modeling methodology that best aligns with the specific constraints and objectives of the design project."
Understanding the spectrum of 3D modeling technologies is crucial for designers and engineers selecting the most appropriate method for their design project. The choice between image-based and scanner-based approaches impacts accuracy, cost, workflow, and the types of objects that can be effectively reconstructed.
What This Means for Your Design
There are two main ways to make a 3D digital model of something real: using lots of photos (like how 3D movies are made) or using a special 3D scanner. Both work, but they are good for different things.

Paragraph starter
The selection of a 3D modeling technology is a critical early decision in a design project involving the digitization of physical objects. As highlighted by Verykokou and Ioannidis (2023), approaches can be broadly categorized into image-based methods, such as photogrammetry, which utilize computer vision algorithms to reconstruct 3D geometry from multiple photographs, and scanner-based methods, which employ dedicated devices like laser scanners or structured light scanners for direct data acquisition. The choice between these families of technologies depends on factors such as the required level of accuracy, the complexity and surface properties of the target object, and the available budget and equipment.
