Low-poly models are 3D representations that use a limited number of polygons, which are the flat shapes that make up the surface of a 3D object. This approach simplifies the design, making it easier to render and process, especially in real-time applications like video games. Low-poly models often have a stylized appearance, focusing on essential shapes rather than intricate details. These models are popular in various fields, including video game development, animation, and virtual reality. By reducing the complexity of the model, developers can improve performance and reduce loading times, making them ideal for mobile devices and online platforms.
