Abstract
The tessellation shader stage of the OpenGL-4 pipeline is widely used for fast tessellations of triangular and quadrilateral shapes and finds applications in the modelling of surfaces with dynamic levels of detail, and real-time rendering of large terrain models. This chapter gives an overview of the tessellation control and evaluation shader stages, and presents algorithms for terrain rendering, procedural heightmap generation and Bezier surface modelling.
