Basics of 3D

Vertices, Edges, and Faces Explained

This section breaks down the three fundamental geometric elements that form the foundation of 3D models. It explains how vertices serve as points in 3D space, edges connect these points to form structure, and faces create the visible surfaces. The cube example is used throughout to make these abstract concepts concrete and relatable.

Understanding Polygons and Meshes

This section explores how polygons (particularly triangles and quads) are organized into meshes. It discusses the difference between high-poly and low-poly meshes, the importance of topology, and how these concepts apply to different industries from film production to video game development.

The Concept of 3D Space and Axes (X, Y, Z)

This final main section explains the three-dimensional coordinate system that provides the spatial framework for all 3D models. It details how the X, Y, and Z axes work, what the origin point represents, and why this coordinate system is essential for all 3D operations.
