The paper presents an improved scheme for the visualization of 3D terrain in real-time using Digital Elevation Model (DEM). The method is primarily based on a modified version of R...
Abstract. While providing non-visual access to graphical user interfaces has been the topic of research for over 20 years, blind users still face many obstacles when using computer...
We address the problem of an efficient image-space reconstruction of adaptively sampled scenes in the context of point-based and line-based graphics. The imagespace reconstruction...

We present a method to efficiently construct and render a smooth surface for approximation of large functional scattered data. Using a subdivision surface framework and techniques...
We present a technique to perform occlusion culling for hierarchical terrains at run-time. The algorithm is simple to implement and requires minimal pre-processing and additional ...
