A team of computer graphics researchers--Xianfeng Gu and Steven Gortler at Harvard and Hugues Hoppe at Microsoft--has devised a unique way to convert the geometry of irregular 3D surfaces that could lead to better image compression and rendering. Instead of representing surface geometry with triangles, the new approach remeshes the surface onto a square structure called a geometry image.
Unlike irregular meshes, these images can be encoded using traditional compression techniques. According ...
