Polycount in 3D modeling refers to the total number of polygons that form a 3D model. It is a critical metric affecting the model’s detail, file size, and performance across applications.
Polygons—typically triangles or quads—are the basic geometric building blocks, so polycount directly reflects a model’s complexity.
For real-time use like video games, lower polycounts are prioritized to ensure smooth rendering and performance. In contrast, high-detail renders (e.g., movies) often use higher polycounts, as performance constraints are less strict here.
In short, polycount balances model complexity and practical performance needs in 3D workflows.
