A detailed relief can be formed only if there are sufficient vertices in the base mesh to depict the new shape. To take the example of the marble carving-if the marble block were made up of eight vertices, no amount of relative displacement between them can produce the relief of a dragon. The reason is that for displacement mapping to be effective, the surface must be made up of a large number of vertices. Like tessellation, displacement mapping has been around for a long time, but until recently, it has never really caught on. Another popular technique is to apply displacement maps over terrain to carve out craters, canyons, and peaks. For example, the graphics artist can take a slab of marble and shift the vertices to form a carving. When applied to a surface, it allows vertices on the surface to be shifted up or down based on the height information. A displacement map is a texture that stores height information. The simplest and most popular way of putting the new triangles to use is a technique called displacement mapping. For example, in a game, it doesnвЂ™t really matter if a square is rendered as two triangles or two thousand triangles-tessellation only improves realism if the new triangles are put to use in depicting new information. By itself, tessellation does little to improve realism. For example, if you take a square and cut it across its diagonal, youвЂ™ve 'tessellated' this square into two triangles. In its most basic form, tessellation is a method of breaking down polygons into finer pieces.

But why is this a big deal? And how does it benefit games? In this article, weвЂ™ll take a look at why tessellation is bringing profound changes to 3D graphics on the PC, and how the NVIDIAВ® GeForceВ® GTX 400 series GPUs provide breakthrough tessellation performance. As a concept, tessellation is fairly straight forward-you take a polygon and dice it into smaller pieces. With the recent buzz around DirectX 11, youвЂ™ve probably heard a lot about one of its biggest new features: tessellation.
