3D Wireframe Graphics

Definition

3D wireframe graphics represent three-dimensional objects using a network of lines and vertices that define their shape. This graphical representation is fundamental in the development of both augmented and virtual reality technologies, serving as an essential step in visualizing complex structures before applying textures and colors. Wireframe models allow for easy manipulation of object geometry and facilitate a better understanding of spatial relationships within 3D environments.
