GPU Terrain Subdivision

and Tessellation

Benjamin Mistal

This paper presents a GPU-based algorithm to perform real-time terrain subdi-

vision and rendering of vast detailed landscapes. This algorithm achieves smooth

level of detail (LOD) transitions from any viewpoint and does not require any

preprocessing of data structures on the CPU.

1.1 Introduction

There are a lot of existing terrain rendering and subdivision algorithms that

achieve fantastic results, and fast frame rates. Some of these algorithms, however,

are limited. They can require the preprocessing of large data sets, constant

transferring of large data sets from the CPU to the GPU, limited ...
