Continuity for Games
The mesh continuity for games is tied to the power of graphic pro-
cessors that draw the polygons in real time. Early game systems
such as Nintendo 64 used very rough quad shapes due to their low
processing capacity. With Doom 3, shape edge continuity has been
raised to a very acceptable quality. What is important to point out is
that games use two types of meshes: high poly for cinematics, teas-
ers, and so on, and low poly for real-time display inside the game.
Continuity for high-poly models is achieved with a subdivision
method, which is done automatically by the 3D application. Continu-
ity for low-poly models is done manually, which means that you
