38 I Geometry Manipulation

2.9 Conclusion

The technique presented in this paper has a number of benefits. It exploits height-

map compression to substantially reduce the storage requirements and uses a

hardware-supported tessellation unit to construct adaptive triangulation. The

decompression is accelerated by the GPU, which improves performance. Pro-

cedural terrain texturing provides a high-quality surface texture with minimal

memory requirements. The technique supports dynamic terrain modifications

making the terrain fully deformable. It exploits a number of technical tricks such

as the use of a texture array and instanced draw calls to improve performance. ...
