In this paper,a terrain render algorithm is developed based on marco-triangle conception,which called Hyper real-time optimally adapting meshes algorithm(Hyper-ROAM).The algorithm can take full advantage of the hardware features of modern GPU,realizing large-scale terrain for real-time continuous level of detail rendering.By adjusting the complexity of macro-triangle,the traditional ROAM becomes a special case of Hyper-ROAM algorithm space.Our tests shown that the traditional ROAM is usually not the best case.It is more efficient to select a proper complexity of the marco-triangles.
