چکیده

This paper presents a novel dynamic terrain multiresolution rendering method by utilizing the capabilities of current generation GPUs. Firstly, the terrain depth offset map texture that represents the appropriate offset values is generated through rendering to texture, which is used to deform terrain in vertex shader. Then in order to accurately represent the fine terrain detail created by deformation, an adaptive geometry tessellation technique is implemented in geometry shader. Moreover, to update deformation area texture, we apply procedural texturing based on constraint conditions in fragment shader. In the end, the experiments prove that our method is feasible and

Reconstruction of Multiresolution Terrain Surfaces

Multiresolution surfaces are especially useful for fast rendering, real-time display and interactive manipulation of large and dense terrain surface models. This paper reviews major multiresolution terrain surface reconstruction techniques and analyses the corresponding data structures. We have proposed and implemented, based on Delaunay retriangulation, a greedy refinement algorithm with a str...

Geometry-based Mapping and Rendering of Vector Data over LOD Phototextured 3D Terrain Models

Interactive three-dimensional (3D) visualization of very large-scale grid digital elevation models coupled with corresponding high-resolution remote-sensing phototexture images is a hard problem. The graphics load must be controlled by an adaptive view-dependent surface triangulation and by taking advantage of different levels of detail (LODs) using multiresolution modeling of terrain geometry....

Irregular Morphing for Real-Time Rendering of Large Terrain

The following paper proposes an alternative approach to the real-time adaptive triangulation problem. A new region-based multiresolution approach for terrain rendering is described which improves on-the-fly the distribution of the density of triangles inside the tile after selecting appropriate Level-Of-Detail by an adaptive sampling. This proposed approach organizes the heightmap into a QuadTr...

Real-Time Extendible-Resolution Display of On-line Dynamic Terrain

We present a method for multiresolution view-dependent real-time display of terrain undergoing on-line modification. In other words, the method does not assume static terrain geometry, nor does it assume that the terrain update sequence is known ahead of time. The method is both fast and space efficient. It is fast because it relies on local updates to the multiresolution structure as terrain c...

JPEG2000–based Compressed Multiresolution Model for Real-time Large- scale Terrain Visualization

This paper presents an effective compressed multiresolution model for interactive large-scale terrain rendering. In contrast to previous approaches, our model enables construction of adaptive terrain triangulation that takes into account local surface features and, at the same time, supports compact representation of the elevation data. The model enables fast extraction of the certain terrain a...
