Advanced View-dependent Techniques for Digital Terrains Visualization

This work presents some methods to improve visualization of a digital featured terrain. We used the wellknown billboard structure and applied approaches such as transparency technique and some view-dependent control like complex object culling and multi-resolution imaging. This work also builds a billboard hierarchy gathering into groups those ones with similar properties. In run-time, the application maps and identifies the correct billboards categories for each scene, getting the most from realism in digital terrains.
