LOW POLY ART
It is a polygon mesh in 3D computer graphics with a relatively small number of polygons. Low-poly meshes occur in real-time applications (video games) and contrast with high-poly meshes in animated movies and special effects of the same era. The term low poly is used in both a technical and a descriptive sense; the number of polygons in a mesh is an important factor to optimize for performance, but can give an undesirable appearance to the resulting graphics
