A Quantitative Analysis of Culling Techniques for Real-time Rendering of Digital Elevation Models
The paper is concerned with investigation of effects of culling techniques on quality and smoothness of terrain data visualization within a 3D interactive environment. We utilize the Real-Time aptimally Adapting Mesh (ROAM) approach, extended with a number of efficient techniques such as implicit co...
