Day 2: Practical Skills & Software

A 3D model is a digital representation of a three-dimensional object created using specialized computer software. Unlike 2D images that only have width and height, 3D models have depth, making them appear solid and realistic. Key characteristics of 3D models: • Mathematical representation of surfaces and volumes • Contains geometric data (vertices, edges, faces) • Can be viewed from any angle • Stores information about shape, size, and structure • Can include color, texture, and material properties 3D models serve as the blueprint for 3D printing, telling the printer exactly what shape to create layer by layer.
