“…Moreover, there is another way to use both the advantages of grid and TIN, which combines the two structures together to create a hybrid terrain model [51,52]. It has the advantage of using finer resolution TINs to represent complex terrain regions or man-made constructions.…”

High-quality terrain rendering has been the focus of many visualization applications over recent decades. Many terrain rendering methods use the strategy of Level of Detail (LOD) to create adaptive terrain models, but the transition between different levels is usually not handled well, which may cause popping artefacts that seriously affect the reality of the terrain model. In recent years, many researchers have tried using modern Graphics Processing Unit (GPU) to complete heavy rendering tasks. By leveraging the great power of GPU, high quality terrain models with rich details can be rendered in real time, although the problem of popping artefacts still persists. In this study, we propose a real-time terrain rendering method with GPU tessellation that can effectively reduce the popping artefacts. Coupled with a view-dependent updating scheme, a multilevel terrain representation based on the flexible Dynamic Stitching Strip (DSS) is developed. During rendering, the main part of the terrain model is tessellated into appropriate levels using GPU tessellation. DSSs, generated in parallel, can seamlessly make the terrain transitions between different levels much smoother. Experiments demonstrate that the proposed method can meet the requirements of real-time rendering and achieve a better visual quality compared with other methods.

“…To visually deal with discontinuities at tile boundaries, vertical wall polygons are constructed between the tile edges. This work was then extended in [6] by associating at each block a precomputed fixed representation, which is chosen among uniform meshes, non-uniform grids, and TINs. This allows nodes that are deep in the tree to represent fine-grained features (such as river beds or roadways) using a TIN representation, while allowing a uniform mesh Survey on semi-regular multiresolution models for interactive terrain rendering 3 representation to be at shallower levels in the tree.…”

Rendering high quality digital terrains at interactive rates requires carefully crafted algorithms and data structures able to balance the competing requirements of realism and frame rates, while taking into account the memory and speed limitations of the underlying graphics platform.In this survey, we analyze multi-resolution approaches that exploit a certain semi-regularity of the data. These approaches have produced some of the most efficient systems to date. After providing a short background and motivation for the methods, we focus on illustrating models based on tiled blocks and nested regular grids, quadtrees and triangle bin-trees triangulations, as well as cluster based approaches. We then discuss LOD error metrics and system-level data management aspects of interactive terrain visualization, including dynamic scene management, out-of-core data organization and compression, as well as numerical accuracy.

“…Currently, a real-time geo-visualization system is being developed on top of VRS [9]. In this application, digital terrain models are represented by specialized shape classes that provide level-ofdetail modeling based on regular grids and TINs [2]. Specialized techniques implement multitexturing used to texture the terrain surface with multiple information layers [8] and a variety of visual effects typically used in flight simulation (including lens flares in the view plane and light reflection at the surfaces of the water bodies).…”

We describe the software architecture of a rendering system that follows a pragmatic approach to integrating and bundling the power of different lowlevel rendering systems within an object-oriented framework. The generic rendering system provides higher-level abstractions to existing rendering systems and serves as a framework for developing new rendering techniques. It wraps the functionality of several, widely used rendering systems, defines a unified, object-oriented application programming interface, and provides an extensible, customizable apparatus for evaluating and interpreting hierarchical scene information. As a fundamental property, individual features of a specific rendering system can be integrated into the generic rendering system in a transparent way. The system is based on a state machine, called engine, which operates on rendering components. Four major categories of rendering components constitute the generic rendering system: shapes represent geometries; attributes specify properties assigned to geometries and scenes; handlers encapsulate rendering algorithms, and techniques represent evaluation strategies for rendering components. As a proof of concept, we have implemented the described software architecture by the Virtual Rendering System which currently wraps OpenGL, Radiance, POV Ray, and RenderMan.
