How to understand polygons 3D models for basics?

For basic understanding of polygon 3D models, they’re 3D shapes built by connecting 2D polygons (like triangles, squares) to form an object’s surface—this is the core concept. Each polygon has vertices (corners) and edges: More polygons mean smoother surfaces, like how a sphere uses tiny triangles to look round. Simple examples help: A cube uses 6 square polygons; a pyramid uses 4 triangles plus 1 square base. Try editing a basic cube in Blender (a free tool)—moving vertices or adding polygons lets you see how the structure works. To wrap up, start with this core idea, then explore parts, examples, and practice—this builds your basic understanding quickly.
