A wireframe is a visual representation of the skeletal structure of a 3D model. It consists of lines and vertices that outline the model’s form without displaying surface details or textures. Wireframes are fundamental in the early stages of 3D modeling, serving as a guide for defining the basic shape and proportions. They provide a clear view of the model’s structure, making it easier for artists and designers to refine and manipulate the geometry.

Imagine designing a car in a 3D modeling software – the wireframe view allows you to focus on the underlying structure, such as the frame and major components, before adding surface details. Wireframes are particularly useful in architectural design, product development, and character modeling, aiding in the visualization and planning of complex 3D shapes.
