Rendering Vector Data over 3D Terrain with View-Dependent Perspective Texture-Mapping: Rendering Vector Data over 3D Terrain with View-Dependent Perspective Texture-Mapping
Article
  • May 2010
This paper presents a texture-based algorithm for vector data display that is able to precisely and efficiently overlay traditional 2D vector data on a 3D multi-resolution terrain model. By the algorithm, depending on the view to the scene first, a perspective projection is created, to match the currently visible range of the terrain. Then the proj...
Research on the Integration Techniques of Task-Oriented Geospatial Information Service for Battlefield
Conference Paper
  • Jul 2009
In order to make a military system more practicable, dynamic and scalable, task-oriented geospatial information service for battlefield (BGIS) need to be established. Information Integration is important means and essential precondition of BGIS construction, so BGIS was researched on from three aspects: service mode integration, service data integr...
MULTI-RANK METHOD: ACHIEVING PROJECTION TRANSFORMATION WITH ADJUSTABLE ACCURACY AND SPEED
Article
In the field of GIS, it is frequently required to carry out projection transformation of massive raster maps or remote sensing images. In this paper, a method named multi-rank method is presented. It is able to achieve projection transformation with adjustable accuracy and speed. All the points in a map or image are divided into four ranks. Rank-4...

... Hong et al. present an approach that renders vector data over 3D terrains using view-dependent perspective texturemapping [21]. Since it is based on texturing only, the major advantage of using TBD is its independent of LOD-Rendering algorithms for DTs. ...

... Different interpolation methods can be used for resampling this type of imagery. An attempt at accelerating raster projection has been presented by Xie et al. (2011). They compute exact analytical projection transformations for a subset of pixels, and apply polynomial interpolation to the remaining pixels using the first subset as control points. ...
